Introducing the virtual infrastructure
VMware® vSphere® provides an innovative mechanism for organizing and viewing any virtual infrastructure built
on its platform. Using a unique combination of physical and logical components, this mechanism effectively and
efficiently fulfills the VMware vision of the modern virtual infrastructure.
Foglight™ for VMware accommodates customers of all sizes that leverage the VMware virtualization platform by
examining and enhancing eminently knowledgeable VMware view of the virtual world.
The following figure highlights the components or objects that make up a typical vSphere implementation. The
figure makes a clear distinction between objects that exist in the physical world and those that are considered to
be virtual.

Figure 1. VMware vCenter Server infrastructure
VMware vCenter® allows for the configuration of a hierarchical organizational structure that resides primarily within
the virtual domain. This enables an organization to easily configure physical VMware ESX® Servers and virtual
machines to reside in logical groups that dictate the various aspects of the virtual infrastructure (like physical
object location, resource allocations and limitations for virtual machines, and high availability settings for physical
and virtual components).
Object roles
Before we get too far into discussing the layout and capabilities of Foglight™ for VMware, we must understand the
different roles the various physical and virtual objects play within the overall virtual infrastructure.
The vCenter® Server and VMware® ESX® Servers provide the physical foundation for the vSphere® infrastructure.
Virtual machines on the other hand are classified as virtual components for the purpose of management and
monitoring, even though they have many of the same characteristics (like direct network and storage access) as
physical systems. At any given time, a virtual machine must be contained within a single VMware ESX Server. The
particular ESX Server in which a given virtual machine is contained may change of course over the lifetime of the
virtual machine through the use of unique VMware technologies such as VMware vSphere® vMotion® or VMware
vSphere® High Availability (VMware HA).
Physical objects
The physical objects within the VMware® virtual infrastructure are those with which you can physically interact.
The virtual components or objects that make up the virtual environment cannot exist without the presence of
underlying physical components.
A VMware ESX® Server is an example of a physical component.
To have Foglight™ for VMware monitor a virtual infrastructure, the virtual infrastructure must consist of at least one
vCenter Server that is used to manage the virtual infrastructure and at least one ESX Server that is used to run
virtual machines.
Foglight for VMware 5.7.3 User and Reference Guide
Using Foglight for VMware
7
NOTE: Each ESX Server that is used to run virtual machines must have its own managing vCenter Agent
installed on it.
ESX Server Hosts
An ESX Server Host is the single physical component required to begin building a virtual infrastructure. An ESX
Server provides a hypervisor based architecture for controlling and managing resources for the virtual machines
that run on it. The virtual machines running on the host share the resources it provides. Should resources become
over-committed, the ESX Server hypervisor determines which virtual machines have priority access to the shared
resources (based on manual virtual machine configurations) and distributes the available resources accordingly.
Each ESX Server is managed by a single vCenter Server instance, and can be configured to exist logically within
either a datacenter or cluster virtual object within the overall virtual infrastructure.
VMware vCenter Server
Although a vCenter Server can technically exist as a virtual machine, it is considered a physical component within
the VMware virtual infrastructure.
VMware vCenter is the software tool used to manage virtual environments that are built on the VMware
virtualization platform. vCenter creates a hierarchical structure of virtual objects that enables a system
administrator to logically lay out his virtual infrastructure configuration. vCenter also introduces other advanced
VMware functionality such as Distributed Resource Scheduling (DRS), VMotion, and High Availability (HA) that
can be used to enhance the benefits of a virtual infrastructure.
vCenter provides a robust WSDL that Foglight for VMware leverages to capture and manipulate key
characteristics and performance metrics of the various object types and objects found within the virtual
infrastructure configuration. Each vCenter instance that is to be monitored using this product must have a VMware
Performance Agent configured for it that points to the Web service interface. As mentioned in the Foglight for
VMware Installation Guide, this agent can be installed on the vCenter Server itself because all of the required
components for the proper operation of the agent come pre-configured.
A single vCenter Server can monitor approximately 100 VMware ESX Servers and 1500 virtual machines before
performance and scalability challenges demand the introduction of a second vCenter Server. Multiple vCenter
instances can be disbursed geographically to localize the management of large, distributed vSphere
implementations.
Virtual objects
Virtual objects can exist only within the confines of the virtual infrastructure. With the exception of virtual machines,
virtual objects are logical and are used for organizing VMware ESX Servers and virtual machines, either
geographically or by function. In addition, virtual objects allow for the advanced configuration of resource
management and of high availability settings.
Virtual machines
The creation and subsequent use of virtual machines is the primary purpose for building and maintaining a virtual
infrastructure. Virtual machines share many of the characteristics of physical systems (like storage and network
interaction), but they do not have direct access to the hardware that is used to process their information and they
are considered virtual components within the virtual infrastructure.
A virtual machine encompasses more than just a guest operating system like Microsoft Windows. A virtual
machine also contains specific configurations that help to define it, such as the number of processors and the
amount of memory it can leverage.
All of the resource utilization for a particular virtual machine on a VMware ESX Server is scheduled through that
Server's hypervisor. The efficient tracking and analysis of this scheduling of resources at both the virtual machine
and the ESX Server Host level is a key function provided by Foglight for VMware.
At any given time a virtual machine must reside on a single VMware ESX Server, but it can be moved across
physical ESX Servers, typically without downtime, through the use of key vCenter functionality called VMotion.
VMotion provides a method for proactively moving a virtual machine from one ESX Server to another while
Foglight for VMware 5.7.3 User and Reference Guide
Using Foglight for VMware

avoiding the downtime that can arise from having to perform actions like patching a physical host server. VMotion
also provides a manual method a system administrator can use to better balance virtual machine workloads based
on resource utilization trends.
A feature called Migration Modeler provides a method for analyzing the impact of using vMotion to move a virtual
machine between two VMware ESX Servers in a cluster. Migration Modeler provides this functionality without you
actually having to move the virtual machine.
Foglight for VMware also provides a mechanism that tracks the life cycle of the virtual machines within the virtual
infrastructure. This enables you to quickly and easily view a history of a virtual machine's performance metrics and
a history of its logical location within the virtual infrastructure.
VMware vCenter offers some additional valuable features that customers may wish to use including the VMware
Distributed Resource Scheduling (DRS) feature for automating the process of balancing VMware ESX Server
utilization and the VMware High Availability (HA) feature for recovering from host failure within a cluster.
Datacenters
A datacenter is the topmost virtual object within a vCenter Server implementation and is required before any
VMware ESX Server Hosts can be added to a vCenter. A datacenter is most commonly used to identify the
physical boundaries within which an ESX Server Host can exist. In most implementations these boundaries
constitute a single physical location that contains a large number of ESX Server Hosts. There is no hard and fast
rule stating that a datacenter must exist entirely at just one physical location, but other datacenter implementations
are atypical of most virtual infrastructures.
Within the boundaries of a datacenter, objects of the same type cannot have the same name. For example, it is not
possible to configure two ESX Server Hosts with the same name to reside within the same datacenter. The same
goes for virtual machines, clusters, resource pools and any other objects that can be created and configured to
reside within a datacenter. Objects of the same type can have identical names as long as they are located in
different datacenters.
Datastores
The management of datastores is carried out at the both the datacenter and the ESX Server levels.
Each datastore is contained within a datacenter and must be uniquely named within its containing datacenter.
A datastore represents a storage location for virtual machine files. The storage location can be a local file system
path, a Virtual Machine File System Storage (VMFS) volume, or a Network Attached Storage directory.
ESX Server Hosts can be configured to mount a set of network drives (or datastores). For each storage location
within a datacenter there is only one datastore, so multiple hosts may be configured to point to the same datastore.
Whenever an ESX Server Host accesses a virtual machine or file within a datacenter it must use the appropriate
datastore path.
Each datastore object keeps a record of ESX Server Hosts that have mounted it, and a datastore object can be
removed only if no hosts are currently mounting that datastore.
Datastores are host-independent and platform-independent. Therefore, they do not change in any way when the
virtual machines contained within them are moved from one ESX Server to another.
VSAN datastores
Virtual SAN (VSAN) is a software component running on the ESXi hypervisor. It collects storage resources
associated with a cluster and creates a storage pool that is accessible to all hosts on the cluster. When Virtual SAN
is enabled on a cluster, a VSAN datastore is created in your environment. VSAN datastores are collections of
storage elements that are available to the hosts.
Clusters
A cluster object is a group of VMware ESX Servers that share common storage resources and network
configurations. A cluster represents a pool of the combined resources of all of the ESX Server Hosts assigned to
the cluster. For example, if four ESX Servers are added to a cluster and each ESX Server has 2x2 GHz
processors with 4 GB of memory, the cluster represents a pool of 16 GHz of CPU processing power and 16 GB of
memory that is available for use by virtual machines.

A cluster also serves as the boundary for virtual machine migration activity through the VMware vMotion or
VMware HA features. When using either of these technologies for virtual machine migration it is critical that the
participating ESX Server Hosts have identical storage resource and network configurations, and this is guaranteed
within a cluster by the very definition of a cluster.
Resource pools
Resource pools enable an administrator to fine tune resource allocations within a cluster. A resource pool can be
configured to leverage a portion of the overall available resources within a cluster and then virtual machines can
be assigned to that resource pool. This enables an administrator to prioritize virtual machines—to either limit or
guarantee certain resources to a particular virtual machine or group of virtual machines.
Resource pools can be configured in many ways, from simple to complex. For a simple example, two resource
pools are configured within a cluster; one is named Production Virtual Machines and the other is named
Development Virtual Machines. The Production resource pool is configured with a “High” share priority and the
Development resource pool is configured with the default “Normal” share priority. In this case any virtual machine
residing in the Production resource pool is automatically given twice the priority, in terms of access to system
resources during periods of contention, of any virtual machine residing in the Development resource pool.
To better demonstrates the true potential of using resource pools, the following is an advanced example. Four ESX
Servers are added to a cluster and each ESX Server has 2x2 GHz processors with 4 GB of memory. The cluster
therefore represents a pool of 16 GHz of CPU processing power and 16 GB of memory that is available for use by
virtual machines. The figure below illustrates that the Production Cluster resource that resides in the Chicago
datacenter has 16 GHz of processing power and 16 GB of memory. A resource pool is created for a CRM
Application that has access to 8 GHz of the cluster’s total CPU resources and 6 GB of the cluster’s total memory.
By drilling down further from there you see that within the CRM Application resource pool there are two more
resource pools (Database and Web). The existence of the Database resource pool ensures that key database
virtual machines have access to the resources necessary to perform their highly transactional operations. The web
servers have access to a smaller portion of the overall resources—just enough to provide the necessary end-user
responsiveness from a web transaction perspective without impacting the key backend database infrastructure.
Figure 2. Resource pool example
To assist with the understanding of these nested relationships of virtualized objects, Foglight for VMware provides
both a Topological and a Hierarchical view of the entire virtual infrastructure as well as resource pool mapping
functionality for maximum flexibility in tracking advanced virtual infrastructure configurations.
Virtual switches
Your VMware environment uses virtual switches to distribute network traffic. A stand-alone ESX host typically uses
a standard virtual switch to manage network traffic to and from virtual machines running on that host. Distributed
Foglight for VMware 5.7.3 User and Reference Guide
Using Foglight for VMware
10
virtual switches manage configuration of proxy switches, enabling communication between a virtual machine using
the distributed switch and any of these components:
•
any other virtual machines on any ESX hosts that use the same distributed switch
•
virtual machines that use a standard virtual switch
•
remote systems on a physical network connected to the same ESX host
In addition to standard and distributed virtual switches, your monitored environment may also include one or more
Cisco virtual switches. A Cisco virtual switch is a third-party distributed virtual switch that manages network traffic
between virtual machines and other components in your integrated virtual infrastructure. For more information
about virtual switches, see your VMware documentation.
Folders
Folders are hierarchical components that exist within a vCenter and they enable an administrator to more easily
organize the virtual environment for manageability. There are three different types of folders that can exist within
the various layers of the virtual infrastructure hierarchy.
The following table lists the available types of folders, and explains the levels at which they can exist and the
objects they can contain.
Table 1. Folder Types
Folder Type
Level at Which It Can Exist
Objects It Can Contain
Datacenter
vCenter Root
Datacenters
Virtual Machine
Datacenter
Virtual Machines and Templates
Compute Resources
Datacenter
Hosts and Clusters
Folders may contain nested folders of the same type, but not of other types. It is not possible, for example, to
create a virtual machine folder within a datacenter folder.
Folders are provided strictly for organizational and management purposes. They offer a way for an administrator to
classify objects that is not tied to (and therefore bound by) the virtual/physical relationship framework. For
example, two datacenter folders are created at a vCenter root; one folder is labelled Primary Datacenters and the
other is labelled Disaster Recovery Datacenters. An administrator can configure multiple primary datacenters
containing production ESX Servers, place those datacenters in the Primary Datacenters folder, and then assign
the necessary permissions to that folder to allow standard users to perform management tasks for the entire
primary virtual infrastructure. The administrator can then configure multiple disaster recovery datacenters
containing disaster recovery ESX Servers, place those datacenters in the Disaster Recovery Datacenters folder,
and assign a different set of permissions to that folder. This prevents standard users from building virtual machines
that may take over resources that are necessarily dedicated to HA-configured disaster failover virtual infrastructure
components.
Using Foglight for VMware, you can observe either a Topology view that does not use folders and presents a
logical breakdown of the virtual infrastructure by component, or a Hierarchy view that uses folders and presents
the familiar interface that is found within the vCenter management server.
Navigation basics
This section describes the basic Foglight™ for VMware navigation techniques necessary for using Foglight for
VMware.
For information about navigation in the browser interface, see Interacting with Foglight for VMware on page 14.
Foglight for VMware 5.7.3 User and Reference Guide
Using Foglight for VMware
11
Foglight for VMware browser interface
elements
Depending on your user roles, you may see either the contents of the first bookmark (the Welcome page is the
default) listed under Bookmarks, or a home page. For further details, see the Foglight User Guide.
Typically, the browser interface is divided into three panels: the navigation panel on the left, the display area in the
middle, and the action panel on the right.
Figure 3. Foglight for VMware Browser Interface
Navigation panel
The navigation panel operates like a drawer. Its default state is open. To close the navigation panel, click the arrow
at the far left of the Foglight for VMware browser interface. Click that arrow again to open the navigation panel.
The navigation panel lists all of the dashboards that are available to the current user for viewing. You can use the
navigation panel to select a dashboard to view in the display area. To access a specific dashboard, open the
appropriate module (the Virtual module, for example).
The navigation panel also provides access to the Foglight for VMware Administration and Configuration areas, and
may provide access to some product-specific navigational views (for example, the Virtual Infrastructure view for
the VMware Explorer dashboard).
If you do not see any dashboards in the navigation panel, the user id with which you signed in may not have been
assigned to a group. For details, see the Foglight for VMware User Help.
Display area
The display area is used to view current dashboards and reports, as well as to create new dashboards and
reports. You can increase the size of this area by resizing the navigation panel, or, if the action panel is open, by
closing the action panel.
Foglight for VMware 5.7.3 User and Reference Guide
Using Foglight for VMware
12
Action panel
The action panel operates like a drawer. Its default state is closed. To open the action panel, click the arrow at the
far right of the Foglight for VMware browser interface. Click that arrow again to close the action panel.
The action panel contains the various actions and tasks you can perform with the current dashboard. It also
contains views and data that you can add to a dashboard or report you are creating and provides access to the
online help files.
Breadcrumbs
If you drill down into various levels across dashboards within Foglight™ for VMware, a trail of breadcrumbs is left at
the top of the current dashboard. This trail provides you with context. It also provides you with the name of the
level you are currently viewing and with a simple mechanism for returning to any of its related parent levels.
The following breadcrumb trail was created while drilling down from the Virtual Environment Summary dashboard
into the VMware Explorer dashboard. Each item within a breadcrumb trail is a hyper link to a previously viewed
parent level.
Figure 4. Breadcrumb trail
For more specific information about the Virtual Environment Summary dashboard or the VMware Explorer
dashboard, see Interacting with Foglight for VMware on page 14.
Time Range
The default behavior of Foglight™ for VMware is to display metrics, alerts, and messages that have occurred
within the last four hours. This time range, however, is configurable.
To configure the Time Range, use the Time Range popup, which you can access from the upper right corner of the
Foglight for VMware browser interface.
Figure 5. Time Range popup
Using the Time Range popup, you can select from predefined time ranges or you can specify a custom range
using either a sliding time bar or calendar precision controls to specify dates and times. When you modify the time
range for a dashboard or view, it adjusts the range for all of the views contained within and drill-downs accessed
from that dashboard or view. It does not adjust the time range for any parent views.
For more information about modifying the time range, see the Foglight User Guide.
Sortable lists
In certain Foglight™ for VMware dashboards, some levels of views contain sortable lists. An example of this is the
VMware Explorer dashboard Related Objects view displayed below.
Foglight for VMware 5.7.3 User and Reference Guide
Using Foglight for VMware
13
Figure 6. Sortable lists
It is possible to sort this list by column using any of the column headings. Click a column heading once to sort the
list in ascending order. The list is redrawn according to your specification. Click the column heading again to resort the list in descending order.
This is handy when you want to have an organized view of virtual machines or host objects sorted by name,
status, or some other criterion.
Alarms and their status indicators
Foglight™ for VMware uses status indicators to show the alarm states of the objects within the virtual
infrastructure. Four status indicators (fatal, critical, warning, and normal), similar to those displayed in the following
image, are used throughout the Foglight for VMware dashboards.
Figure 7. Alarm indicators
The Foglight for VMware alarm types respond to thresholds that are defined within the Foglight for VMware rules.
As metrics change and move through thresholds, alarms are raised. As a metric moves through thresholds, the
severity of an alarm changes, which causes the associated status indicator to change.
For detailed information about the rules included with the product, see Rules on page 264.
It is important to note that any events that trigger an alarm for an object do not trigger an alarm for any of the
object’s parents. For example, a single virtual machine running at a high CPU utilization does not trigger an alarm
for its parent ESX® Server. An alarm would only be triggered for the parent ESX Server if the server itself was
running at a high CPU utilization.
Mouse-over actions
Many items within the Foglight™ for VMware dashboards display additional information when you hover the cursor
over them. For example, when you hover the cursor over a graph you are likely to see a specific value or values
that correspond) to the position of the cursor. When you hover the cursor over an individual metric, you are likely to
see a small descriptive popup.
Interacting with Foglight for VMware
When you deploy Foglight™ for VMware, a set of predefined dashboards enables you to view the performance of
your virtual system at a glance. They allow you to ensure consistent application performance by drilling down for
details from higher-level components such as clusters, hosts, and virtual machines, to viewing detailed specifics
about each component, such as CPU utilization and network I/O.
First, familiarize yourself with roles needed to access different parts of the browser interface included with the
product (see About VMware roles). Then, ensure your monitored agents are configured for data collection. You do
that by navigating to the Administration tab of the VMware Environment dashboard. This tab lists the available
Foglight for VMware 5.7.3 User and Reference Guide

agents and shows their status, and provides access to other administrative tasks. For more information, see
Exploring administrative tasks on page 16 and Configuring monitoring agents for data collection on page 17.
Start by looking at the status of your integrated system by navigating to the VMware VirtualCenters dashboard.
This dashboard shows the status of each of the Virtual Centers within the infrastructure and the related elements
such as datacenters, clusters, hosts, resource pools, and virtual machines. For more information, see Viewing the
overall system status on page 22.
From there, navigate to the Monitoring tab of the VMware Environment dashboard. Select a specific object or
group of objects, such as monitored clusters, servers, and virtual machines, and look at the detailed metrics about
the CPU load, network I/O, total memory, or disk space consumed by that specific component or group of
components. To see more details about the selected server or virtual machine, use the VMware Explorer. For more
information about these dashboards, see Exploring your VMware environment on page 22 and Investigating
performance metrics on page 26.
Next, review the alarms that are generated against your environment and, if required, set their sensitivity level.
The Administration tab on the VMware Environment dashboard enables you to configure the level of alarm
sensitivity. The alarm sensitivity reflects the level of alarms the system stores and displays. For more information,
see Exploring VMware alarms on page 37.
The VMware Explorer’s Administration tab provides access to common administrative tasks that you can use to
manage monitored servers and virtual machines directly from the Foglight for VMware browser interface. For
example, use this tab to shut down or reboot monitored servers, create virtual machines, and grant them access to
system resources, create virtual machine snapshots or automate system workflows. For more information, see
Administering monitored ESX hosts and virtual machines on page 39.
To read about additional features, such as planning for virtual machine migrations, creating OS mapping rules, or
reviewing topology object instances and expired data, see Additional features on page 52.
About VMware roles
The Management Server relies on roles to control user access. Each user can have one or more roles. The roles
granted to a user determine the set of actions that the user can perform. The Management Server includes a set of
built-in roles that control access to dashboards and reports included with the Management Server. The following
roles are included with Foglight™ for VMware to control access to the dashboards and reports:
•
VMware Administrator: This role provides full access to all product components, views and reports.
•
VMware Automation User: Users with this role can access the VMware Explorer Administration tab. This
tab provides quick access to common administrative tasks that include server shutdown, virtual machine
creation, resource allocation, and others.
IMPORTANT: Executing VMware administration tasks, such as rebooting an ESX® host or a VM,
require specific VMware® permissions.
•
VMware Operator User: This role restricts the user to the VMware Environment and VMware Explorer
dashboards only, except the Administration tab, and NetFlow Setting and Cisco Setting dialog boxes.
Attempts to navigate to these elements result in the following message: Sorry. The view is not
authorized.
•
VMware QuickView User: This role restricts the user to the VMware Environment dashboard only. Attempts
to navigate to the VMware Explorer result in the following message: You are not authorized to
access view “VMware Explorer”.
•
VMware Report User: This role grants access to the Foglight for VMware reports only. None of the VMware
views are accessible if this is the user’s only role. To work with reports, the user additionally requires the
Reports Manager role.
For more information about roles, users, and security, see the Administration and Configuration Help.

Configuring monitoring agents for data
collection
Foglight™ for VMware uses the VMware Performance Agent to collect information from monitored environments.
Creating a VMware Performance Agent instance creates the agent process on the Agent Manager host. Activating
the VMware Performance Agent starts that agent process while starting an agent instance’s data collection
enables the agent to start collecting data from the monitored vCenter® and to send it to Foglight for VMware.
When the VMware Performance Agent package is successfully deployed, create one or more agent instances,
activate them, and start their data collection. To perform these steps in a single operation for one or more
monitored hosts, use the Agents view on the Administration tab.
Foglight for VMware 5.7.3 User and Reference Guide
Using Foglight for VMware

Each VMware Performance Agent monitors a single Virtual Center. When you create a VMware Performance
Agent instance and the Agent Setup wizard determines that the Virtual Center was not previously monitored by
this Foglight instance, it starts importing historical data into Foglight. This data is not immediately available as it
takes some time to collect it. This process can import data collected over 30 days or less, depending on the
amount of data available in the Virtual Center. This allows you to explore VMware metrics as soon as the data is
imported, instead for waiting for the agent to collect some data from the Virtual Center. The Metric History column
in the Agents table indicates the progress of the historical data import. Historical data is intended for charting,
trending, and general presentation purposes. It does not cause any alarms to fire.
To import vCenter historical data, the minimum recommended vCenter Statistics Levels must be at least 2 in the
samples that are collected for one month for the agent to populate 30 days of historic collections. The following
table lists the minimum Statistics Levels for all collection frequencies. For more information about vCenter
Statistics levels, see your VMware® documentation.

Viewing the overall system status
The VMware VirtualCenters dashboard has just one view that displays a Status view for each vCenter that exist
within the virtual infrastructure. This dashboard and its embedded status views can be used to take a quick look at
the status of each of the vCenters within the infrastructure.
Figure 18. VMware VirtualCenters dashboard
Each vCenter Status view provides an alarm summary for the objects contained within the vCenter. If you click any
of the alarm indicators in the alarm summary, an Alarms popup appears showing a list of alarms for the object type
that is associated with the alarm indicator.
To access this dashboard, from the navigation panel, under Dashboards, choose VMware > VMware
VirtualCenters.
For reference information about the data appearing on this dashboard, see .
Exploring your VMware environment
A typical virtual environment contains a set of ESX® host and virtual machines. An ESX host can be a part of a
cluster, and can have one or more virtual machines associated with it. Other components of a Virtual Center
include datacenters, resource pools, and data stores. You can view the overall state of these components on the
VMware Environment dashboard.
Selecting an object or group of objects, such as clusters, servers, or virtual machines, shows additional
information about your selection. For example, selecting all ESX hosts identifies the top three consumers of CPU,
memory, network, and disk resources and shows the related alarm states. Selecting a specific ESX host shows the
CPU, memory, network, and disk usage for the selected ESX host, along with high-level hardware and software
configuration.

The list shows a list of services. Each service can contain a different combination of monitored components.
NOTE: The VMware Environment dashboard is service-based. The VMware service created by Foglight for
VMware for a particular vCenter does not contain template virtual machines (VMs). The VMware Explorer
dashboard is inventory-based. The VMware Explorer dashboard counts all VMs, including template VMs, for
each vCenter. Therefore, the number of VMs for a particular vCenter is different when you view it through the
VMware Environment dashboard than the number that appears when you view it through the VMware
Explorer dashboard.
The VMware Environment dashboard is made up of the following views: the Virtual Environment Overview and
Quick-View. Selecting an object type and its alarm state in the Virtual Environment Overview shows the summary
information for your selection in the Quick-View. For reference information about the data appearing on this
dashboard, see VMware Environment views on page 162.
For example, when you select the Normal state on the ESX Hosts tile, the ESX Hosts that are in the Normal state
are listed in the ESX Hosts view, and summary information for those ESX Hosts appears in the ESX Hosts
Summary view.
In the example below, the ESX Hosts tile is selected. The ESX Hosts view is populated with all monitored ESX
Hosts regardless of their alarm state. Summary information for those ESX Hosts appears in the ESX Host
Summary view.
From there, clicking a specific object instance on the left shows additional summary information about the selected
object. The Inventory view, for example, shows all of the objects related to the selected object, along with their
respective alarm state counts. All objects in the object relationship hierarchy, including the selected object, are
shown in the Inventory view, so that you see the entire relationship hierarchy for the selected object. Each level in
the hierarchy is labelled with the corresponding object type name. When there is only one object at a particular
level in the hierarchy, the object name is displayed instead of the object type name.
The next example shows a number of virtual machines that are associated with a selected Virtual Center. Clicking
that number shows a popup with the list of virtual machines. You can click any object in the popup list to quickly
navigate to the VMware Explorer dashboard, and review detailed information about that particular object.

NOTE: The VMware Explorer dashboard is inventory-based. The VMware Explorer dashboard counts all
virtual machines (VMs), including template VMs, for each vCenter. The Virtual Environment Summary
dashboard is service-based. The VMware service created by Foglight™ for VMware for a particular vCenter
does not contain template VMs. Therefore, the number of VMs for a particular vCenter is different when you

Virtual Environment Summary dashboard.
To access this dashboard, from the navigation panel, under Dashboards, click VMware > VMware Explorer. For
complete reference about the data appearing on this dashboard, see VMware Explorer views on page 76.
The VMware Explorer dashboard contains the following views: the Virtual Infrastructure view and VMware
Explorer Primary view.
The Virtual Infrastructure view contains a navigation tree on the Topology tab that represents the various virtual
infrastructure objects: Virtual Centers, Datacenters, Clusters, ESX Hosts, Resource Pools, and Virtual Machines.
For each individual object or group of objects, a status indicator appears, showing the alarm of highest severity
that is outstanding for the that object or objects. For example, there are 25 virtual machines configured for a
vCenter. Twenty of the virtual machines have a normal status, three have a warning status, and two have a critical

who leverage Foglight for VMware to monitor their virtual infrastructure.
Figure 27. VMware Explorer
The alarm summary in the top-right shows the number of alarms at each severity level that are outstanding for the
selected object. Clicking an alarm count lists the active alarms for the object.
A set of tiles displayed along the top indicate the type of the selected object or objects, and the related alarm
counts.
Additionally, a collection of navigation tabs appears in this view. These navigation tabs vary from object to object,
but generally contain a tab to an object summary (typically the default view), a tab to an object performance
overview, and one or more tabs to other relevant information.
The display area changes in appearance and content, depending on the selected object or group of objects. For
example, if you select an object type container from the Topology view, the Summary tab displays a consumption
graph and a table that are representative of the group of objects within that container.

However, selecting a Resource Pool container from the Topology tab displays a Resource Pools Relationship Tree
on the Summary tab. This tree contains every resource pool that belongs to the clusters within the associated
vCenter. This is useful if you want to see how those resource pools are laid out, or if you want to take a look at the
utilization statistics for each configured resource pool on the vCenter.
Figure 29. Resource Pool tree
If you select an individual resource pool from the Virtual Infrastructure view, the Summary displays summary and
utilization information for that resource pool. This is typically the type of information you see on the Summary tab
when you select any individual object from the Virtual Infrastructure view.

Figure 30. Resource Pool Summary
The metrics and the amount of detail displayed in the display area vary depending on the type of the selected
object. For example, in the image below, the tiles indicate that the selected object is the STL DEV datacenter, and
that it is connected to one vCenter, one cluster, four ESX® Hosts, and so on.
Figure 31. Datacenter Summary
The Utilizations view, typically located across the center of the display area tab, provides numerical and graphical
representations of utilization metrics associated with the selected object or group of objects. For example,
selecting a single resource pool from the Virtual Infrastructure view and opening the Performance tab in the
Foglight for VMware 5.7.3 User and Reference Guide
Using Foglight for VMware
31
display area, displays four graphs in the Utilizations view, showing CPU, memory, disk, and network resource
utilizations for the selected resource pool.
Figure 32. Resource Utilization views
From there, clicking a graph or a spinner shows a larger view of the graph with descriptive text about each metric
appearing in the graph.
Figure 33. Resource Pools, CPU Utilization drilldown
If you open the VMs tab for that same resource pool, the Utilizations view displays one graph illustrating the
percent-used and percent-ready CPU utilization for the virtual machines of the resource pool.
Foglight for VMware 5.7.3 User and Reference Guide
Using Foglight for VMware
32
Figure 34. Resource Pools, VM CPU Utilization drilldown
If, however, you select a collection of ESX Hosts from the Virtual Infrastructure view and you open the Summary
tab, an informative graph appears in place of a Utilizations view. Selecting a collection of objects in the Virtual
Infrastructure view always shows a composite view displaying information about all object instances contained in
that collection.
Figure 35. Combined CPU Consumption
In addition to the Utilizations view, one or more Related Objects views may appear at the bottom of the display
area. These views take the form of tables and list either the parent or child objects or both (whichever are
applicable) of the object being viewed, and provide pertinent details about each one. Their appearance depends
on the type and range of objects selected in the Virtual Infrastructure view.
For example, if you select a single cluster, two Related Objects views appear: one displaying the ESX hosts that
belong to their cluster, and another listing the virtual machines running on those hosts. The views also display the
performance metrics associated with each list item.

specific information on the vmAlarms dashboard, see Exploring VMware alarms on page 37.
View Object IDs
Under the Actions heading, the View Object IDs link takes you to the Object IDs dialog box. The Object IDs dialog
box lists all of the objects in the virtual infrastructure with their type and object ID. The object IDs are the true
names of the objects. To produce component-specific thresholds, context is required in the form of the relevant
object ID.
To narrow down the list of objects, type a relevant text string in the search field provided and click Search. You can
type things like a portion of the object type name (for example, server), a portion of the object name (for example,
part of the IP address), or a portion of the object ID. To clear the Search box, click Clear.
For more advanced search options, click Advanced. To narrow down the list to objects of a particular type, type
the object type name in the Type box. To find the object by name, type the object name in the Name box. To find
the object by ID, type the object ID in the Object ID field.
Viewing baseline ranges
Foglight can estimate system performance by comparing metric values against a baseline range. A baseline
establishes expected data patterns during a given time period. This feature is only available when your Foglight
system includes a baseline cartridge with applicable metric definitions. Foglight for VMware uses the capabilities of
the IntelliProfile cartridge, which enables the appearance of baseline data for ESX hosts and virtual machines on
the VMware Environment and VMware Explorer dashboards.

Administering monitored ESX hosts and virtual
machines
A VMware® environment typically includes one or more Virtual Centers. A Virtual Center includes a collection of
datacenters, clusters, ESX® hosts, resource pools, and virtual machines. Data centers are typically used to define
physical boundaries within which ESX hosts exist, while resource pools enable an administrator to fine-tune
resource allocations within a cluster. A cluster can have one or more ESX hosts associated with it, and one or
more virtual machines can run on each ESX hosts. Each virtual machine is allocated a portion of the ESX host’s
resources, including disk, CPU, memory, and network resources. A virtual machine has its own machine name and
IP address, and it runs a guest OS (for example, MS Windows XP), along with other applications.
Additionally, VMware implements the concepts of virtual machine snapshots and ESX host workflows. A virtual
machine snapshot is a virtual machine image that you can return to at any point in time. A workflow, on another
hand, is a way to automate ESX host tasks, and re-run them using a different set of parameters. For example, you
can use an existing virtual machine creation task, change some of its resource allocation parameters, and run it
again.
These actions require that you set up credentials for the virtual center on the Automation Configuration dashboard.
To do that, on the navigation panel, under Dashboards, choose VMware > Automation Configuration. On the
Automation Configuration dashboard that appears, in the Virtual Infrastructure view, select a virtual center, click
Assign Credential, and provide host credentials in the Assign Host Credentials Dialog box. Failing to configure
host credentials results prevents the automated tasks from being executed.

allocation. This tab also provides quick access to creating and editing virtual machine snapshots and ESX host
workflows.

Figure 80. Migration Modeler
The VMware Modeler dashboard provides four graphs that show current and projected numbers, for CPU and
memory utilization and network and disk activity, on the target ESX Host over the time range specified in the
VMware Explorer dashboard.
The blue area on the graphs represents current consumption or activity on the target ESX Host. The orange area
specifies projected worst case consumption or activity. The red dotted line specifies the target ESX Host capacity
with respect to the corresponding metric. For reference information about the data appearing on this dashboard,
see VMware Modeler views on page 160.
To run the Migration Modeler:
1
From the VirtualCenter list, select the vCenter within which the migration will take place.
2
From the Virtual Machine list, select the virtual machine that is to be migrated.
3
From the Target Host list, select the ESX Host that will be the target for the migration.
When using the VMware Modeler dashboard, you should extend the time range in order to better assess the long
term impact of the potential migration. For specific information about adjusting dashboard time ranges, refer to the
Foglight for VMware User Guide.
Creating OS mapping rules
OS mapping involves associating various versions and editions of a particular operating system with a common
OS name. You configure OS mapping rules using the Administration tab on the VMware Environment
dashboard. This helps Foglight for VMware map the OS names reported by Foglight for VMware to those reported
by physical OS monitoring, so that you can view all Windows machines, all Linux machines, and so on.
For reference information about this view, see OS Mapping view on page 213.
To configure OS mapping rules:
•
On the VMware Environment dashboard, open the Administration tab and click Configure OS Mapping.

environment can have a unique set of object types. Foglight for VMware includes a set of topology object types
and their definitions. When Foglight collects data from your VMware environment, it builds the topology model that
consists of the instances of the object types defined by Foglight for VMware. By default, a monitored environment
can result in up to 50,000 object instances being created by a single object type. This value is controlled by the
foglight.limit.instances registry variable.
Registry variables have a global default value and type-specific scoped values. This means that different object
types can have different instance limits.
Explore the Instances and Limits view to see the existing VMware object types. To access this view, on the
VMware Environment dashboard, open the Administration tab, and click Review Instances and Limits.
Figure 83. Instances and Limits
The Instances and Limits view displays the list of the existing VMware object types, and for each type it shows
the type name, instance limit, instance count, instance limit utilization, and the current status given as a highest
severity level associated with an instance of that type. This information can give you insight into the size of your
database and whether additional adjustments are required to improve your system performance. For example, if
an object type results in a high number of object instances, this may result in performance bottlenecks. To prevent
them, check if any of these are updated recently and, if not, delete them from the database.
To view the list of existing registry variables or to edit them, click Edit Registry Variable in the top-left corner. For
complete information about registry variables, see the Administration and Configuration Help.
For reference information about this view, see Instances and Limits view on page 212.

VMware Performance Agent
configuration
The VMware Performance Agent collects data from the virtual infrastructure and sends it to the <Product
Name>™ Management Server. The agent keeps track of resource utilization metrics and alerts you when certain
pre-defined thresholds are reached.
VMware Performance Agent and Agent
Manager configuration
On 64-bit hosts meeting the minimum system requirements, the embedded Agent Manager can be used to run
VMware Performance Agents to monitor up to 500 virtual machines. If the total number of virtual machines to be
monitored from a single agent host is greater than 500, an Agent Manager should be installed on a separate host.
IMPORTANT: Foglight for Virtualization, Enterprise Edition Virtual Appliance comes pre-configured to
support up to 4,000 virtual machines. If you are using this product, there is no need to follow the
configuration procedure described in this section.
If additional cartridges and agents are added to the environment, product performance should be monitored and
agents moved off of the embedded Agent Manager to reduce the load.

Monitoring more than 4000 virtual machines from a single
agent host
The Agent Manager JVM usually requires additional memory to monitor more than 4000 virtual machines. The
total number of virtual machines is the total from all vCenters that will be monitored from all VMware Performance
agents running on the Agent Manager.
The following calculations are guidelines, not hard and fast rules. Memory requirements can vary greatly from
installation to installation with similar VM counts. If insufficient memory is configured, the failure mode is easily
recognizable: all agents on the Agent Manager host will go into a broken state after the agent(s) were activated for
a short period of time, usually within 24 hours. In addition, the Agent Manager log will contain a line similar to the
following:
Caused by: java.lang.OutOfMemoryError: Java heap space
If this is the case, add memory greater than what is shown in the calculations below, in increments of 512 MB until
the agents stabilize.
JVM memory requirements for VMware Performance agents are calculated using the following formula:
512 MB + 0.5 MB/VM
According to the above formula, monitoring 4000 virtual machines requires 2560 MB of memory:
512 MB + 2048 MB = 2560 MB
This is the default setting for agents deployed on 64-bit systems.
Similarly, monitoring 8000 virtual machines requires 4608 MB of memory:
512 MB + 4096 MB = 4608 MB
This requires a change in the default Agent Manager settings.
To change the JVM memory settings:
1
Determine the amount of additional memory required. This will be the total from the last step above minus
the default value of 2560 MB. In the example above, this is 4608 MB – 2560 MB = 2048 MB.
2
On the agent machine, open the baseline.jvmargs.config file for editing. The file is located in the
<Agent_Manager_home>/state/default/config directory.
3
Add the following lines to the memory settings section:
vmparameter.0 = "-Xms2048m";
vmparameter.1 = "-Xmx2048m";
NOTE: If this file has been previously edited have been made to this file, increment the numeric
parameters accordingly.
4
Delete the existing deployed negotiation configuration settings directory:
<Agent_Manager_home>/state/default/config/deployments
5
Restart the Agent Manager for these settings to take effect.
Host system recommendations
Dedication
When monitoring larger vCenters, the Agent Manager machine hosting the VMware Performance agents should
be dedicated to this task. No other Foglight agent types should run on the host and the host should not run any
other applications.
Foglight for VMware 5.7.3 User and Reference Guide
Using Foglight for VMware
63
Memory
Regardless of the values set for JVM memory above, Agent Manager never allocates more than 80% of system
memory. So the machine hosting the Agent Manager and VMware Performance Agents must have sufficient
memory. Beyond the memory requirements of the Agent Manager, a minimum of 2 GB should be free for the
operating system. In the example above for 8000 VMs and an Agent Manager memory requirement of 4608 MB,
the host should have a minimum of 6656 MB - the greater of:
1.25 x 4608 MB = 5760 MB
Or:
2048 + 4608 MB = 6656 MB
If the Agent Manager is configured on a virtual machine, it is recommended that the VM use a memory reservation
to ensure maximum performance.
CPU
CPU usage on the Agent Manager host is relatively low most of the time. However, usage peaks dramatically
during the performance metric collection. This is normal and expected. CPU utilization consistently over 50% is an
indication that additional processing power is required. As with memory, usage can vary between different
installations with similar numbers of virtual machines. The following guidelines should be followed.
Table 6. CPU usage guidelines
Up to 1000 VMs
2 CPUs
1000 – 4000 VMs
4 CPUs
4000+ VMs
add 1 CPU per 1000 VMs – round up when necessary
When the Agent Manager and VMware Performance agents are running on a virtual machine, the VM should be
configured with CPU reservation whenever possible to ensure best performance. Lack of processing power on the
Agent Manager manifests in missed collections and gaps in the data usually noticeable in various graphs
throughout the Foglight for VMware dashboards.
Configuring agent properties
When an agent connects to <Product Name>™, it is provided with sets of properties that it uses to configure its
correct running state. Each agent is provided with a combination of two types of properties: agent properties and
shareable properties.
Default versions of these properties are installed with Foglight for VMware. However, you can edit the default
shareable and agent properties, configure agent properties that apply only to a specific agent instance, and create
edited clones of shareable properties that are used by a subset of agents of a certain type.
There are two ways to access the VMware Performance Agent properties:
•
On the VMware Environment dashboard, on the Administration tab, select an agent instance and click
Edit Properties (see Configuring monitoring agents for data collection on page 17). This method only
provides access to the Configuration properties, but not the Black List and Data Collection Scheduler
properties.
•
On the Agent Status dashboard, select an agent instance and click Edit Properties. This method provides
access to the full set of VMware Performance Agent properties, and is described in this topic.
For more information about working with agent properties, see the Administration and Configuration Guide.
To modify agent properties:
1
Log in to the Foglight browser interface.
2
Ensure that the navigation panel is open.
To open the navigation panel, click the right-facing arrow
on the left.

global and private properties. Global properties apply to all instances of the agent type, while private
properties apply only to specific agent instances.
a
On the navigation panel, under Dashboards, choose Administration > Agents > Agent Status.
IMPORTANT: Another way of editing the VMware Performance Agent properties is through
the Agent Properties dashboard. The properties you specify on this dashboard apply to all
instances of the VMware Performance Agent type. To be certain that you are editing
properties for a particular agent instance, without overwriting any properties of other VMware
Performance instances, use the Agent Status dashboard instead of the Agent Properties
dashboard.
b
On the Agent Status dashboard, select the instance of the VMware Performance Agent whose
properties you want to modify and click Edit > Edit Properties.
c
Click Modify the private properties for this agent to indicate that you want to edit the properties
of the selected VMware Performance Agent instance.

To set the Duplicate VM List properties:
1
Locate the VMware Performance Agent’s Duplicate VM List properties.
2
Set the Duplicate VM List properties as follows:
▪
Duplicate VM List MOR: Select a list in which you want to specify the duplicated virtual machines.
You can select or clone an existing list, and edit it, as required. The default list is
duplicateVMListList. Lists can be shared between multiple agent instances. For more
information about list properties, see the Administration and Configuration Help.
For each directory entry in the list, set its Duplicate VM Item property to contain the managed

Setting the Black List properties
In some rare cases, the VMware Performance Agent can encounter ESX® hosts and virtual machines for which it
cannot collect data. To prevent these problems, the VMware Performance Agent detects these entities, excludes
them from data collection, and adds them to the agent black list.
Any metrics associated with these objects are not included in roll up performance metrics. When an entity is added
to the agent black list, an agent message and alarm are generated makes you aware of the problem so that you
can investigate it further in the monitored VMware® environment. When the issue with the entity is resolved, it can
be removed from the agent black list. The next available performance collection includes this entity in the data
collection request.
In addition to the list that is populated by the agent, there is a user-populated black list. You populate this list by
adding ESX hosts and virtual machines that you want to exclude from data collection. This feature enables
Foglight administrators to disable data collection for certain ESX hosts and virtual machines, which also prevents
their performance metrics from being submitted to Foglight.
Foglight for VMware 5.7.3 User and Reference Guide
Using Foglight for VMware
68
CAUTION: Black listing an ESX host disables data collection for that ESX host, including the
collection of virtual machine, storage, and network metrics for that host.
Any metrics associated with these objects are submitted as part of roll up metrics. For example, if a virtual
machine that appears on the user-populated black list is part of a resource pool, the virtual machine performance
metrics are included with the performance metrics of other virtual machines from the same resource pool. This
resource pool performance data is collected and submitted to Foglight. At the same time, the black-listed virtual
machine object will not appear to have any performance metrics stored for this object. ESX hosts are handled the
same way in terms of rolling up performance data for clusters, datacenters, or the Virtual Center.
Each ESX host or virtual machine entry in the user black list should include the Managed Object Reference (MOR)
value. The MOR value is assigned to monitored objects in the monitored VMware environment and is collected by
Foglight for VMware. This value is stored in the Managed Object Reference property of ESX host and virtual
machine objects. You can use the Data Browser to find out the MOR values for those ESX hosts or virtual
machines that you want to exclude from data collection.
The agent checks both lists during data collection. You can remove entities from either list, as required. For
example, if you resolve an issue with a virtual machine that causes data collection problems, you can remove the
virtual machine from the black list.
For any ESX hosts or virtual machines that you want to exclude from data collection an entry should exist in the
agent or user black lists. While you can add entries to the user lists, agent black lists should only be populated by
the VMware Performance Agent. Any ESX hosts or virtual machines for which you want to enable data collection
must have their entries removed from either black lists.
Every VMware Performance Agent instance is associated with an agent and a user black list. Each agent instance
should maintain a unique pair of these lists. Because list properties in Foglight (also known as secondary
properties) are shareable properties, meaning that they are accessible to all agent instances of the type in which
they are defined, you should clone an agent and a user black list for each agent instance and give them unique
names.
Entities included in these lists are not included in the collection of performance metrics. Other collections are not
affected by their contents.
To set the black list properties:
1
Locate the VMware Performance Agent’s BlackList properties.
2
Associate this agent instance with a user black list.
a
Choose the user black list that you want to use for this agent instance. Click the User BlackListed
MORs list, and select the black list. The default list is userBlackList.
b
Clone the selected list to create a unique user black list for this agent instance. Click Clone on the
right.
The Clone userBlackList dialog box appears.
Figure 89. Clone userBlackList dialog box
c
In the Clone userBlackList dialog box, type the name of the user black list. It is recommended to
use a syntax that makes the list name unique and easily associated with this agent instance. For
example: <list_name>_<agent_name>
d
Click OK to close the Clone userBlackList dialog box.
The newly cloned user black list is now associated with this agent instance.

IMPORTANT: For any ESX hosts or virtual machines that you want to exclude from data collection,
an entry should exist in the agent or user black lists. While you can add entries to the user lists, agent
black lists should only be populated by the VMware Performance Agent. Any ESX hosts or virtual
machines for which you want to enable data collection must have their entries removed from either
black lists.

Virtual Infrastructure view
Purpose
The Virtual Infrastructure view provides an organized view of the various virtual infrastructure objects that are
monitored by Foglight for VMware. It serves as a navigation tool, and it also presents pertinent alarm information.
When you select an object from the Virtual Infrastructure view, all of the views in the VMware Explorer dashboard
are updated with information pertaining to that object.
How to Get Here
•
Open the VMware Explorer.
The Virtual Infrastructure view appears on the navigation panel.
Description of Embedded Views
The Virtual Infrastructure view is made up of the following embedded views:
•
Topology Tab
•
Hierarchy Tab
•
Mouse-over Status Popups
Topology Tab
The Topology view is organized into a tree using object type (or topology type) containers for branches.
Foglight for VMware 5.7.3 User and Reference Guide
Reference
154
Within the Topology view, all of the virtual infrastructure objects are organized into a tree using object type (or
topology type) containers for branches. The top-level objects in the Topology view are always the vCenters.
The top-level objects in the Topology view are always the VirtualCenters.
Each VirtualCenter in the Topology view contains several object type containers, and each object type container
contains every object of that particular type that is managed by the parent VirtualCenter.
Each object type container, as well as each object, has a representative icon that is displayed to the left, as shown
in the following table.

At the right, the Topology view displays status indicators. For an individual object, the status indicator represents
the alarm of highest severity that is outstanding for that object. For an object type container, the status indicator
represents the alarm of highest severity that is outstanding for all objects of that type.
NOTE: A single virtual machine running at a high CPU utilization does not trigger an alarm for its parent ESX
Server. An alarm is only triggered for the parent ESX Server if the server itself is running at a high CPU
utilization.
Hierarchy Tab
The Hierarchy view represents the logical layout of VirtualCenter management servers, so it is not organized into
groups of common objects.
Within the Hierarchy view, each VirtualCenter object is organized into a tree that has the same hierarchical
structure as the VirtualCenter and displays the objects (datacenters, clusters, resource pools, virtual machines,
folders, etc.) within the VirtualCenter as branches.
In the Hierarchy view, each VirtualCenter object is organized into a tree that has the same hierarchical structure as
the corresponding VirtualCenter, displaying the objects (for example, datacenters, clusters, resource pools, virtual
machines, and folders) within the VirtualCenter as branches.
Each object in the Hierarchy view has a representative icon that is displayed at the left of the object’s name. These
icons are shown in the table in Topology Tab on page 154.
At the right, the Hierarchy view displays status indicators. Each status indicator represents the alarm of highest
severity that is outstanding for the corresponding object.
Mouse-over Status Popups
When you hover the cursor over an object in the Virtual Infrastructure view, you see a popup that provides a
summary of the present state of that object.
Foglight for VMware 5.7.3 User and Reference Guide

The following image shows the popup you see when you hover the cursor over a VirtualCenter object in the Virtual
Infrastructure view.
VMware Explorer Primary view
The VMware Explorer dashboard has a Primary view that takes up the entire display area of the Foglight for
VMware browser interface. For more information about the VMware Explorer dashboard, see Investigating
performance metrics on page 26.
Purpose
The VMware Explorer Primary view is the most content-intensive view in Foglight for VMware. It provides access
to summary (of alarm, resource, and other) information for the object being viewed in the VMware Explorer
dashboard, as well as detailed information on performance with respect to the four core ESX infrastructure
resources: CPU, memory, disk, and network usage. This view provides a great deal of value to administrators who
leverage Foglight for VMware to monitor their virtual infrastructure.
Foglight for VMware 5.7.3 User and Reference Guide
Reference

Figure 221. VMware Explorer Primary view
It provides navigation tabs that can be used to view a variety of valuable information pertaining to the object being
viewed.
Content and Embedded Views
The metrics and the amount of detail displayed in the Primary view vary depending on the type of object you
select.
The Primary view changes in appearance and content, depending on which navigation tab and embedded view
you have selected.
The VMware Explorer Primary view heading, located at the top of the VMware Explorer Primary view, consists of
three main components: an icon and text that specify the type of selected object or object container (from this point
on, these two are referred to simply as object, unless otherwise specified), an alarm summary for the selected
object, and navigation tabs.
The alarm summary at the right of the Primary view heading shows you the number of alarms at each severity
level that are outstanding for the selected object. When you click an alarm count, you get a popup that lists the
active alarms for the object.
The navigation tabs are located immediately below the selected object’s name. These navigation tabs vary from
object to object, but generally contain a tab to an object summary (typically the default view), a tab to an object
performance overview, and one or more tabs to other relevant information.
The Primary view changes in appearance and content, depending on which navigation tab and embedded view
you have selected. For example, if you select an object type container from the Topology view, the Summary tab in
the Primary view displays a consumption graph and a table that are representative of the group of objects within
that container. However, if you select a Resource Pools container from the Topology view, the Summary tab in the
Primary view displays a Resource Pools Relationship Tree that contains every resource pool that belongs to the
clusters within the associated VirtualCenter.
If you select an individual resource pool from the Virtual Infrastructure view, the Summary tab in the Primary view
displays summary and utilization information for that resource pool. This is typically the type of information you see
for the Summary tab when you select any individual object from the Virtual Infrastructure view.

historical data into Foglight. This data is not immediately available as it takes some
time to collect it. This process can import data collected over 30 days or less,
depending on the amount of data available in the Virtual Center. This allows you to
explore VMware metrics as soon as the data is imported, instead for waiting for the
agent to collect some data from the Virtual Center. Historical data is intended for
charting, trending, and general presentation purposes. It does not cause any alarms
to fire.
Click this column to start a metric history import, or to see its progress. When the
import is in progress, you have an option to cancel it, if needed.

Topology views
Purpose
A typical VMware environment consists of many interrelated components. Understanding the dependencies
between specific components in your monitored environment and the levels of resources they consume allows you
to better understand resource-related issues, potentially affecting the stability of your system. This can help you
predict the impact a potential outage may have on your environment, and to prevent such events, by reallocating
resources where they are most needed.
The VMware Environment dashboard includes several topology views that visualize the relationships between the
objects in your environment through an interactive dependency map. The map illustrates how different
components relate to each other, and the levels of the available resources available to them.
Figure 410. Topology view
The complexity of the information appearing in a dependency map depends on the selected object and the
dependencies that object has with other objects within your integrated infrastructure.
In a large multi-component environment, dependency maps are likely complex and may not fit your screen. The
NAVIGATOR in the top-right corner allows you to easily set the zoom level by dragging the slider into the
appropriate position.
Figure 411. Navigator view
In a dependency map, some objects are represented with container tiles, others with single-object tiles or just
icons. Every object in the map includes an indicator of its health.
Figure 412. Object health indicators
Dependencies between the objects in a map are illustrated with single-directional arrows. The color of the arrow
reflects the alarm state of the target object: gray for Normal, yellow for Warning, orange for Critical, and red for the
Fatal state.

To find out more about an object appearing in the dependency map, click the object icon. A dwell appears,
displaying more details about that object. The type and range of information appearing in the dialog box depends
on the selected object’s type. For example, drilling down on a virtual switch shows the switch name, alarm counts
top virtual machine consumers, levels of traffic utilization, percentage of packet loss, current traffic types, available
bandwidth, the numbers of available and all ports, and the number of active versus standby NICs.

Rules
Foglight™ for VMware allows you to create flexible rules that can be applied to complex, interrelated data from
multiple sources within your distributed system. You can associate several different actions with a rule, configure a
rule so that it does not fire repeatedly, and associate a rule with schedules to define when it should and should not
be evaluated.
Different types of data can be used in rules, including registry variables, raw metrics, derived metrics, and topology
object properties.
There are two types of rules in Foglight for VMware: simple rules and multiple-severity rules. A simple rule has a
single condition, and can be in one of three states: Fire, Undefined, or Normal. A multiple-severity rule can have up
to five severity levels: Undefined, Fatal, Critical, Warning, and Normal.
Rule conditions are regularly evaluated against monitoring data (metrics and topology object properties collected
from your monitored environment and transformed into a standard format). Therefore, the state of the rule can
change if the data changes. For example, if a set of monitoring data matches a simple rule’s condition, the rule
enters the Fire state. If the next set does not match the condition, the rule exits the Fire state and enters the
Normal state.
A rule condition is a type of expression that can be true or false. When it evaluates to true, the rule is said to fire,
causing any actions that are associated with the rule or severity level to be performed. You can configure a rule to
perform one or more actions upon entering or exiting each state. When a multiple-severity rule fires, an alarm also
appears in Foglight for VMware.
For more information see the Foglight for VMware Administration and Configuration Help.
Foglight for VMware provides an effective monitoring solution for the VMware infrastructure. The rules included in
Foglight for VMware alert you to virtual infrastructure problems.
When service degradations are detected, Foglight for VMware sends alerts to the event console. Optionally,
Foglight for VMware can be configured to send emails, pager messages, or perform other actions you define.
Performance data can be viewed, analyzed and reported using Foglight for VMware.
Foglight for VMware includes a number of predefined rules that capture the expert knowledge of our virtualization
specialists and are used to monitor the health of your virtual infrastructure. Foglight for VMware allows you to
modify these rules or create your own flexible rules that can be applied to complex, interrelated data from multiple
sources within your distributed system.
In this chapter, rule descriptions are organized into logical groupings. To see a rule description, select the
appropriate grouping from the sections listed below.
Many of the rules listed and described in this chapter have thresholds (standard deviations, utilization
percentages, etc.) defined within them. Those thresholds are default values predefined in the registry.

Collecting performance data for one or more specific
entities has caused the performance data request to the
vCenter to fail. No further performance data will be
collected for these entities. Please review the status of
these entities in the VMware Environment and address any
serious issues that may have occurred. Once the entities
are operating normally, they can be removed from the
Agent-Managed Blacklisted Entities list and performance
data collections will resume for the entities. Consult the
Foglight for VMware documentation for the procedure for
removing an entity from the Agent-Managed Blacklisted
Entities list.
Possible solutions:
•
Resolve any errors with these entities in the virtual environment.
Collecting performance data for 25 or more specific entities
has caused the performance data request to the vCenter to
fail. Due to the size of this number it is likely that an issue
with the virtual environment is the root cause and these
entities are not specifically at fault. Please resolve any
known environment issues. If the situation continues,
please contact Quest Support.
Possible solutions:
•
Resolve any known environment issues.
An unexpected issue occurred during data collection from
the vCenter. Please review your environment to ensure that
data collection has resumed in a normal fashion. If there is
