Configuring a Performance Statistics Task

This section describes how to configure a performance statistics task. After the performance statistics collection interval is set and an instance is bound to a performance statistics task, the system starts collecting the performance statistics.

Context

A performance statistics task enables the system to periodically collect performance statistics for a service. In a performance statistics task, basic performance statistics functions are implemented, and performance statistics files can be generated.

Perform the following steps on the device:

Procedure

Run system-view
The system view is displayed.
Run pm
The performance management (PM) view is displayed.
Run statistics enable
The performance statistics function is enabled.
Run statistics-task task-name
A performance statistics task is created, and the performance statistics task view is displayed.
Run statistics-cycle cycle
The performance statistics collection interval is set.
Run binding instance-type instance-type { all | instance { vpn-instance-name } & <1-8> }
An instance is bound to the performance statistics task.

After an instance is bound to a performance statistics task, the system collects the performance statistics about the instance and generates a statistics file.
(Optional) Run measure disable instance-type instance-type measure measure-name
Measurement is disabled for a statistics counter of the instance bound to the performance statistics task.

To view statistics counters of the instance bound to a performance statistics task, run the display pm measure-info instance-type instance-type-name command. To deactivate a specific statistics counter of the instance bound to a performance statistics task, run the measure disable instance-type instance-typemeasure measure-name command to disable the measurement for the statistics counter.
Run either of the following commands:
- Run the record-file disable command to disable the generation of a performance statistics file.
  
  Run this command when you do not want the system memory to be occupied by many performance statistics files.
- If the performance statistics file generation function is left enabled, you can run the record-interval interval command to set the number of intervals at which performance statistics are collected.
  
  After the command is run, the system generates performance statistics files every cycle x interval minutes and automatically saves the performance statistics in the files.
  
  Run the file-format { text | xml } command to set the format for performance statistics files.
Run commit
The configuration is committed.
