Overview

The vFoglight module contains various tools to monitor schema and data objects as well as to monitor the vFoglight Management Server.

The vFoglight module contains the following dashboards and group of dashboards:

• Agents

• Diagnostic (Log Analyzer dashboard and Performance-related dashboards)

• Schema Browser

• Servers (vFoglight Management Server, MySQL database, Persistence Handler)

Viewing Logs

You can display multiple log files in vFoglight to view and analyze known events and error conditions such as verbose or informational type of messages. The Log Analyzer dashboard enables you to navigate, view, and download logs. The time, level, source, and description of log messages is displayed for logs you view in this dashboard.

To view logs:

1 On the navigation panel under Dashboards , click vFoglight > Diagnostic > Log

Analyzer > Overview .

Note You can also access the Log Analyzer dashboard through the Administration dashboard if you have access to the vFoglight Administration functions. On the navigation panel, under Dashboards, click Administration > Administration . In the

Navigation view, under Tooling and Diagnostics, click Server Log Overview .

The vFoglight Log overview dashboard appears.

Viewing Performance-related Dashboards

vFoglight includes a set of diagnostic dashboards which are useful for analyzing the performance of a vFoglight Management Server as well as diagnosing problems relating to the Management Server, agents, database, etc.

The following performance-related dashboards are available:

• Overview Tab

Displays database activity, data service performance, JVM performance and server load on one dashboard.

Inspecting Object Types

• Derivation and Query Tab

Shows activity in the derivation and query service such as the number of evaluations, rulettes, errors, and cache performance.

141

Inspecting Object Types

Use the Schema Browser dashboard located in vFoglight > Schema to view information about data object types such as check which types are available, search for specific types, understand the relationship between types, and view instances of a particular type.

Viewing a Data Object

The Schema Browser dashboard allows you to browse through the vFoglight

Management Server connections and view the structure of the database and the schema objects to understand the structure and dependencies of the objects.

To view an object:

1 On the navigation panel, under Dashboards, click vFoglight > Schema >

Schema Browser.

Find the data type in the list.

• To apply a filter to narrow down the search criteria, type a character in the

Filter box (for example, “Host”) and press Enter .

• To see the full list of data types, clear the Filter and press Enter .

When you select an object type, you can sort by various constituents of the object by using the View by options: Properties , Ancestors , Decendants , and

Instances .

Cleaning up Data Objects

143

Cleaning up Data Objects

The vFoglight Data Management dashboard is useful for inspecting and deleting data objects, and particularly for cleaning up objects that are no longer needed. For instance, if a set of agents is no longer required, the objects created by those agents will still be visible in the user interface. Removing these objects can have a positive impact on the performance of vFoglight and ensure that only necessary information is maintained in the database.

As an example, deleting agent instances from the Services dashboard removes the agent definitions. However, you can still view the agent entries in other dashboards such as the dashboard for Oracle. To remove the agent entries from these dashboards, you need to delete the agents using the vFoglight Data Management dashboard to remove the services and OracleModel Instances that was created for the Oracle dashboard.

Deleting a Data Object

The Delete option removes an object and all of its children. If you delete an object that is still active, it will be re-created.

Note Metrics are always preserved and deleted as part of this topology maintenance operation.

Figure 2

To delete a data object:

1

On the navigation panel, under Dashboards , click vFoglight > Servers > Data

Management .

Drill-down to the data object you want to delete.

Click Delete beside the object to remove the object and all of its children.

Click Yes to the “Are you sure you want to delete this object” confirmation message.
