Commands for monitoring cluster performance

You can use the statistics commands to display performance data and specify the settings for displaying the data. For more information about these commands, see the man pages.

Collecting data for objects by using performance presets

You can use the following commands to collect and view data samples for objects. Each of the following commands is associated with a performance preset that defines what counters collect data for the object. It is noted when one of the following commands requires advanced privilege.

If you want to... Use this command...
Collect and view data samples for aggregates statistics aggregate show
Collect and view data samples for caches statistics cache flash-pool show
Collect and view data samples for disks statistics disk show

This command is available at the advanced privilege level.

Collect and view data samples for logical interfaces (LIFs) statistics lif show
Collect and view data samples for LUNs statistics lun show
Collect and view data samples for each node in the cluster statistics node show
Collect and view data samples for FC ports statistics port fcp show
Collect and view data samples for a cluster statistics system show
Collect and view data samples for volumes statistics volume show
Collect and view data samples for Storage Virtual Machines (SVMs) statistics vserver show
Collect and view data samples for QoS workloads statistics workload show

This command is available at the advanced privilege level.

Viewing performance presets

You can use the following commands to view performance presets. The following commands require advanced privilege.

If you want to... Use this command...
View all performance presets statistics preset show
View details of each performance preset statistics preset detail show

Creating, modifying, and deleting performance presets

You can use the following commands to create, modify, and delete performance presets. The following commands require advanced privilege.

Note: You cannot modify or delete read-only performance presets. You can only modify and delete performance presets that have the read-only parameter set to false.
If you want to... Use this command...
Modify properties of a performance preset, such as the name or comment statistics preset modify
Create or modify a performance preset by importing an XML file of definitions statistics preset import

Contact technical support for help with creating the XML file of definitions.

Delete a performance preset statistics preset delete

Collecting data for a sample time period by using advanced methods

You can use the following commands to collect data samples and to manage the samples that you collect. You must collect a data sample before you can use the statistics show command. The following commands require advanced privilege.

If you want to... Use this command...
Start data collection for a sample statistics start

You can use a performance preset to collect data by using the -preset parameter.

Stop data collection for a sample statistics stop
View all samples statistics samples show
Delete a sample statistics samples delete

Viewing performance data by using advanced methods

You can use the following commands to view performance data. You must collect a data sample before you can use the statistics show command. The following commands require advanced privilege.

If you want to... Use this command...
View performance data for a sample time period statistics show

You should limit the scope of this command to only a few objects at a time to avoid a potentially significant impact on system performance.

View continuously updated performance data statistics show-periodic

This command is deprecated, but you can still use it to view performance data.

Viewing all objects, instances, and counters

You can use the statistics catalog commands to view information about objects, instances, and counters. The following commands require advanced privilege.

If you want to... Use this command...
View descriptions of objects statistics catalog object show
View all instances of an object statistics catalog instance show
View descriptions of counters in an object statistics catalog counter show

Managing settings for the statistics commands

You can use the statistics settings commands to modify settings for the statistics commands. The following commands require advanced privilege.

If you want to... Use this command...
View the settings for the statistics commands statistics settings show
Modify whether the commands display rate statistics in rates per second. statistics settings modify

Viewing advanced performance data

Although the following commands are deprecated, you can currently still use them to view advanced performance data about your cluster. The following commands require advanced privilege.

If you want to... Use this command...
View information about SecD RPC usage statistics for the nodes in the cluster statistics secd show

Use this command only as directed by support personnel to help analyze performance and diagnose problems.
