Configure File System Analytics (FSA) job settings 13

Configuration

Managing File System Analytics result sets

The File System Analytics feature allows you to view File System reports.

When File System Analytics (FSA) is enabled on a monitored cluster, a File System

Analytics job runs on the cluster and collects data that InsightIQ uses to populate file system reports. You can modify how much information is collected by the FSA job through OneFS. You can also configure the level of detail displayed in file system reports through InsightIQ.

Note

When enabled, the FSA job consumes computing resources on the monitored cluster and can affect cluster performance. If cluster performance is negatively affected, you can disable the FSA feature. Disabling the FSA job prevents the job from running.

File System Analytics (FSA) result sets overview

InsightIQ generates all File System reports from File System Analytics (FSA) result sets.

If File System Analytics (FSA) is enabled for a monitored cluster, InsightIQ generates

File System reports from FSA result sets. Each File System report is generated from a single FSA result set.

Unlike InsightIQ data sets, which are stored in the InsightIQ data store, result sets are stored on the monitored cluster in the /ifs/.ifsvar/modules/fsa directory. The monitored cluster routinely deletes result sets to save storage capacity. You can manage result sets by specifying the maximum number of result sets that are retained.

You can configure whether File System reports are visible on the InsightIQ web application and whether new File System reports are generated on the monitored cluster. You can view any existing File System reports, even when the cluster does not generate new reports.

Disabling the FSA job does not affect any of the existing result sets. Result set expiration occurs based on the maximum number of result sets configured. If a result set is marked to be saved, or pinned, it is not deleted. By default, the monitored cluster generates one result set per day.

Note

This note applies to versions of OneFS earlier than 8.0.

If NFS is disabled on the monitored cluster, and File System Analytics reports are viewable in the InsightIQ web application, the InsightIQ installation continues to generate FSA connection errors. These errors are generated even if new reports are not created on the monitored cluster.

File System Analytics result set attributes

The Manage FSA Result Sets section on the Manage FSA Result Sets tab of the

Configuration view displays information about all retained File System Analytics result sets.

The following list describes each column in the Manage FSA Result Sets table.

Configuring cluster monitoring

InsightIQ can monitor multiple clusters.

You can configure InsightIQ to monitor more than one EMC Isilon cluster. The maximum number of clusters that you can simultaneously monitor is based on the system resources available to the Linux computer or virtual machine. It is recommended that you monitor no more than 8 clusters or 150 nodes with a single installation of InsightIQ.

Monitor a cluster

Configure InsightIQ to monitor a cluster.

Before you begin l l

Verify that a valid InsightIQ license is enabled on the cluster that you want to monitor. For more information, contact an Isilon representative.

Verify that a local user account for InsightIQ is enabled and configured with a password on the cluster that you want to monitor.

16 InsightIQ 4.1.1 Administration Guide

Configuration

Note

It is recommended that you monitor clusters over a LAN connection. Monitoring clusters over a WAN connection can significantly degrade the performance of

InsightIQ.

Procedure

1. In the InsightIQ web application, click the Settings tab and then Monitored

Clusters on the Settings ribbon, and then click Add Cluster.

The Add Cluster dialog box appears.

Note

The first time that you configure InsightIQ, the Add Cluster dialog box might already be displayed.

2. In the Add Cluster dialog box, in the Isilon cluster address field, type the hostname or IP address of any node of the cluster that you want to monitor. If the monitored cluster is running OneFS 7.2.1 or later, you can specify an IPv4 or

IPv6 address. If the cluster is running an earlier version of OneFS, you can specify only an IPv4 address.

Alternatively, you can type the name of an Isilon SmartConnect zone.

Specify IPv6 addresses without surrounding brackets. You can connect to an

NFS data store over IPv6 only if IPv6 addresses are configured for both the

InsightIQ instance and the monitored cluster.

Note

In general, it is recommended that you specify a cluster by a SmartConnect zone name. If the cluster has high usage and you use InsightIQ file-heat data, it is recommended that you specify the cluster by the IP address or by the hostname of a specific node.

Avoid specifying an IP address that can be transferred from one node to another node. If you choose to identify the monitored cluster by a

SmartConnect zone, specify a SmartConnect zone that includes a CPU loadbalancing policy. By balancing connections to nodes with lower CPU usage, the monitored cluster can respond to InsightIQ data collection queries more quickly and efficiently.

A green icon indicates that communication between the monitored cluster and InsightIQ is normal with no errors.

Yellow

A yellow icon indicates that communication between the monitored cluster and InsightIQ has been temporarily interrupted. This error might be due to a brief timeout. This error condition typically resolves automatically.

Delete an InsightIQ data store 19

Configuration

Red

A red icon indicates that communication between the monitored cluster and InsightIQ has been interrupted indefinitely. This error might be due to an authorization issue, an unconfigured license, or a prolonged timeout. An administrator must resolve this error condition.

Gray

A gray icon indicates that InsightIQ monitoring is suspended and that there is no communication between the monitored cluster and InsightIQ. To resume InsightIQ monitoring, click Resume in the Actions column.

Configuring data stores

Manage the InsightIQ data store.

InsightIQ data is stored in either the local data store that is part of the InsightIQ installation or on any NFS-based server, including an Isilon cluster. You can move the

InsightIQ data store to a new location and migrate all information from the current data store to the new location. If InsightIQ monitors the cluster that contains the data store, the cluster appears as a client of itself in the InsightIQ web application.

InsightIQ data store size

Information on the size of InsightIQ data stores.

An adequate amount of disk space must be available for InsightIQ to store data. The amount of data that InsightIQ requires depends on the number of nodes that are monitored and the length of time that you want InsightIQ to retain data.

On average, InsightIQ creates 1 GB of data for each monitored node every 2 weeks. If you want to retain more than 2 weeks of data, it is recommended that you increase the size of the InsightIQ data store by 2 GB for each node each month. It is also recommended that the disk space always includes at least 10 GB of free space.

Use the following equations to calculate the minimum and maximum size of the data store:

<minimum_datastore_size> = <number_of_nodes>*1 + 10 GB

<larger_datastore_size> = <number_of_nodes>*<number_of_months>*2

+ 10 GB

There is no maximum size for an InsightIQ data store. The size of the InsightIQ data store does not significantly affect InsightIQ performance.

If InsightIQ is unable to free at least 5 GB of disk space, InsightIQ stops monitoring the cluster. If the data store has less than 3 GB of free space available, InsightIQ begins to delete older data to create space for new data. To resume monitoring, increase the amount of available disk space or manually delete data from the data store.

For example, if you monitor 12 nodes, it is recommended that you reserve at least 22

GB of disk space. If you want to retain the data for 3 months, it is recommended that you reserve 82 GB of disk space.

Note

To receive an email when the data store is reaching capacity. Set up an email alert from the InsightIQ web application Status view

InsightIQ 4.1.1 Administration Guide

Configuration

InsightIQ is unable to delete the following types of data from the data store:

Data store requirements for an Isilon cluster

InsightIQ requirements when using an Isilon cluster to store data.

This information is applicable only if you store data on an Isilon cluster.

l l l l l

Verify that the Isilon OneFS operating system supports the version of InsightIQ to be installed.

Verify that a valid InsightIQ license is activated on the cluster. If you store

InsightIQ data on an Isilon cluster that is not a monitored cluster, it is necessary to license InsightIQ for the monitored cluster.

Verify that the server includes a correctly configured NFS export rule. The export rule must export the data store path, and map the root user on the InsightIQ server to the user account that owns the export on the NFS server.

Enable read and write access to the export. Isilon OneFS ships with a default NFS export rule for the /ifs directory that you can use for InsightIQ. If that default

NFS export has been modified or deleted, create NFS export rule that allows write access for InsightIQ.

Do not apply a quota to the InsightIQ data store through the SmartQuotas module.

If you limit the size of the InsightIQ data store through a quota, InsightIQ cannot detect the available space. The data store might become full before InsightIQ can delete older data to make space available for newer data.

Data store requirements for NFS

InsightIQ data store requirements for NFS servers.

As an alternative to storing InsightIQ data on the local data store, you can store

InsightIQ data on any NFS-mounted server. If you store InsightIQ data on an NFS server, the NFS server must meet the following requirements.

l l l l

Enable read and write access to the export rule. This configuration allows InsightIQ to mount the server and create the necessary directories and files on the server.

InsightIQ might cache permissions for failed tries to mount the NFS-based server.

If InsightIQ continues to report insufficient rights to create the path on the NFS server, restart InsightIQ to clear the previous mount tries, and then try again.

You can connect to an NFS data store over IPv6 only if IPv6 addresses are configured for both InsightIQ and the NFS server.

Configuration

Move a data store

Move an InsightIQ data store to a new location.

Before you begin

It is recommended that you back up the data store before moving InsightIQ to a new location. If InsightIQ is unable to complete the migration process, InsightIQ data is permanently split between the old and the new data store locations. If you have a backup of the data store, you can import the backup to the new InsightIQ installation and recover the data. You back up the data store by exporting data store to a .tar file.

The new data store location cannot contain an existing InsightIQ data store.

Procedure

1. In the InsightIQ web application, click the Settings tab and then click

Datastore.

2. Specify the data store location.

l l

To migrate data to a local data store, click Local Datastore and then select the location for the export data.

If InsightIQ is installed on a virtual machine, the local data store is on a virtual hard drive that is configured on the virtual machine. If InsightIQ is installed on a Linux computer, the local data store is on the hard drive of the

Linux computer.

If you want to store the InsightIQ data as a local data store, verify that there is at least 70 GB of free disk space available.

To migrate data to an NFS data store, click NFS Mounted Datastore, and then specify the address of the NFS server and select the location for the export data.

The NFS data store can be stored on either an Isilon cluster or on another

NFS-mounted server. If you want to store InsightIQ data on an NFS server, verify that the data store meets the requirements for an NFS server. Refer

to the topic, Data store requirements for NFS on page 21, for more

information.

3. Click OK.

Automatic data pruning

InsightIQ deletes older data when a data store runs out of disk space.

When the InsightIQ data store fills the storage capacity of the disk, InsightIQ deletes the oldest data until storage capacity has increased.

If multiple clusters are monitored, InsightIQ favors deletion of the oldest data among all the clusters. For example, if ClusterA has data from January 2013, and ClusterB has data from January 2015, the data from ClusterA is deleted until the oldest data has the same date as the data on ClusterB.

InsightIQ suspends monitoring the cluster.

InsightIQ tries to delete the oldest data store summary data. If InsightIQ cannot delete data store data, it suspends monitoring.

Troubleshooting data store issues

If InsightIQ cannot write to the data store, check the following settings.

If the InsightIQ data store is on an Isilon cluster and an NFS data store permissions error message appears, verify that a valid NFS export is configured on that cluster.

The NFS export must be configured to grant write access to the root user. This configuration enables InsightIQ to mount the cluster or server and create the necessary directories and files on the cluster or server. InsightIQ connects to the NFS host as the root user. The configured NFS export must grant the root user write access for the specified InsightIQ virtual machine IP address.

If InsightIQ is configured to use a local data store and a permissions error message appears, connect to the virtual machine command-line interface. Then, verify that the parent directory of the data store is configured with a permission setting of 755 or higher.

If InsightIQ cannot write to the data store, review the permissions settings for the data store directory and for all the files contained in the directory. All the files in the data store directory must be configured with a permission setting of 744 or higher. If the issue persists, verify that the directory's owner and group settings are correctly configured. For an NFS data store, the owner:group setting must be

nobody:nobody

For a local data store, the owner:group setting must be

root:root

Troubleshooting data retrieval issues

Guidance on data retrieval problems.

If you experience Data Retrieval Delayed errors, consider disabling the retrieval of a specific data set. If InsightIQ is unable to retrieve a data set, disabling retrieval for delayed data sets removes the Data Retrieval Delayed errors caused by those data sets. Disabling retrieval can be useful if you are receiving Data Retrieval Delayed errors for data sets that you do not care about and want to reserve those errors for data sets that you do care about.

Troubleshooting data store move issues

If there is not enough free space on the target data store or if an NFS connection gets interrupted, the data store move operations can fail.

If InsightIQ is migrating data from or to an NFS data store, and the connection to the

NFS data store is interrupted, InsightIQ stops migrating data until the connection is restored. If the connection is permanently severed, you can recover the data only if you have created a backup of the data store by exporting it to a .tar file. If you have created a backup, you can import the backup data store to a new instance of InsightIQ to recover the data. For this reason, The recommendation is to back up the data store before moving an InsightIQ data store.

InsightIQ tries to calculate whether there is enough free space on the target location before migrating data. However, if a quota is applied to the target location and the quota is configured to report the size of the entire file system instead of the quota limit, there is less space on the target location than InsightIQ requires. The migration might fail. If this failure occurs, InsightIQ automatically transfers the data store back to the original data store.

Configuring LDAP for authentication

Enable InsightIQ to use an LDAP server for authentication.

You can configure Lightweight Directory Access Protocol (LDAP) as the authentication method for accessing InsightIQ. Once LDAP is enabled, InsightIQ checks the configured LDAP server's users and groups for authentication. The LDAP server, as well as its users and groups, must be configured on the LDAP server before

InsightIQ can use the information for authentication.

Troubleshooting InsightIQ

Troubleshooting overview

Overview of troubleshooting indicators.

In the upper-right corner of the InsightIQ web interface, the InsightIQ Status area displays at-a-glance information about the status of InsightIQ.

The status of InsightIQ is indicated by color:

Green

InsightIQ is operating normally.

Yellow

At least one transient, nonfatal error has occurred.

Red

InsightIQ could not save data to the data store. For example, InsightIQ could not save data to the data store because the data store is full or because InsightIQ could not contact the server hosting the data store. InsightIQ does not collect additional data until the issue is resolved.

Troubleshooting configuration issues

Troubleshoot InsightIQ configuration issues.

Troubleshooting InsightIQ configuration issues typically fall into one of two general categories: InsightIQ virtual machine configuration issues, and monitored cluster configuration issues.

Virtual machine configuration issues

If InsightIQ does not detect a virtual machine network adapter during the boot process, shut down the InsightIQ virtual machine. Then, check the settings for the network adapter, and ensure that the network type is correct for the virtualization environment. For example, if you reconfigure the network adapter to run in bridged mode. If this issue persists, delete the network interface in the virtualization environment, add network interface, and then restart the InsightIQ virtual machine.

If you cannot log in to the InsightIQ web application, open the InsightIQ virtual machine command-line interface and configure InsightIQ networking to run in DHCP networking mode. Then try accessing the InsightIQ web application through the

DHCP-generated IP address. The results can indicate whether the issue is related to the IP address.

Monitored-cluster configuration issues

If InsightIQ cannot connect to the monitored cluster, try to ping the IP address of any node in the cluster. If you cannot ping a cluster node, verify that the node at the specified IP address is operating correctly and that the IP address is valid. If the issue persists, try connecting to a different node in the monitored cluster by the node's hostname or IP address. If the issue persists, configure a SmartConnect zone on the monitored cluster, and then try to connect to that SmartConnect zone instead of a hostname or IP address.

If an Unlicensed error message appears, log in to the monitored cluster and verify that a valid InsightIQ license has been activated on the cluster.

If an Unauthorized error message appears, verify that the local InsightIQ or OneFS

Platform API user on the monitored cluster is enabled and is configured with a valid

38 InsightIQ 4.1.1 Administration Guide

Troubleshooting InsightIQ password. Verify that the corresponding InsightIQ user settings in the InsightIQ application match the settings that are configured on the monitored cluster.

Note

The local user on the monitored cluster is the InsightIQ user named InsightIQ.

Troubleshooting memory issues

Troubleshoot issues with memory and timeouts.

If many breakouts or data modules are applied to a single report, InsightIQ might run out of memory, causing data modules to timeout.

If a timeout occurs, restart InsightIQ by running the following command: iiq_restart

Troubleshooting InsightIQ web application issues

Troubleshoot issues with the InsightIQ web application.

If you are unable to access the InsightIQ web application through a web browser, the browser might be trying to access InsightIQ through an incorrect port or the InsightIQ web application might be unable to communicate with InsightIQ.

Some web browsers automatically store the port number through which a site is accessed the first time that the browser goes to the site. If you access InsightIQ before modifying the InsightIQ port, the web browser might later try to connect to

InsightIQ through the original port. To resolve this issue, clear the cache of the web browser and then connect to InsightIQ.

If the issue persists, verify that InsightIQ is running, and then try to ping InsightIQ or log in through another supported browser. If you are still unable to access the

InsightIQ web application, log in to the InsightIQ command-line interface and restart

InsightIQ by running the following command: iiq_restart
