Usage guidelines

To configure performance statistics tasks, you must enter performance management view.

Examples

# Enter performance management view.

sample interval

Use sample interval to set the performance sampling interval.

Use undo sample interval to restore the default.

Syntax

sample interval interval

undo sample interval

Default

The default sampling interval varies by the statistics interval, as shown in Table 4.

Predefined user roles

Parameters

interval: Specifies the performance sampling interval in seconds. The available sampling interval values vary by statistics interval, as shown in Table 4.

Usage guidelines

A shorter sampling interval produces more precise statistics but consumes more resources.

When you change the statistics interval, the system automatically changes the sampling interval to the corresponding default.

The default sampling interval and the possible sampling interval values vary by statistics interval, as shown in Table 4.

Table 4 Sampling interval defaults and available sampling interval values

Statistics interval (minutes)	Default sampling interval (seconds)	Available sampling interval values (seconds)
5	5	5, 10, 15, and 30
10	5	5, 10, 15, 30, and 60
15	5	5, 10, 15, 30, and 60
30	60	5, 10, 15, 30, and 60
60	300	5, 10, 15, 30, 60, and 300
1440	900	300, 600, 900, 1800, and 3600

 

When the sampling interval changes for a performance statistics task, the system automatically deletes all performance statistics for the task and recollects the performance statistics.

Examples

# Set the sampling interval to 300 seconds for performance statistics task task1.

<Sysname> system-view

[Sysname] performance-management

[Sysname-pm] statistics task task1

[Sysname-pm-task-task1] statistics interval 60

[Sysname-pm-task-task1] sample interval 300

statistics interval

Use statistics interval to set the performance statistics interval.

Use undo statistics interval to restore the default.

Syntax

statistics interval interval

undo statistics interval

Default

The performance statistics interval is 15 minutes.

Parameters

interval: Specifies the performance statistics interval in minutes. Values include 5, 10, 15, 30, 60, or 1440.

Usage guidelines

A performance statistics task can have only one statistics interval. A statistics interval change takes effect immediately on all instances in the performance statistics task.

A shorter statistics interval produces more precise statistics but consumes more resources.

After you set the statistics interval for a performance statistics task and enable performance statistics, the device uses the following rules to determine the start time for the task:

·     If the interval is less than or equal to 60 minutes, the start time is the beginning of the next complete period. For example, if you set the performance statistics interval to 15 minutes and enable performance statistics at 8:40, the start time is 8:45.

·     If the interval is greater than 60 minutes, the start time is 00:00 in the morning on the next day.

When you change the statistics interval for a performance statistics task, the system automatically performs the following operations:

·     Changes the sampling interval to the corresponding default shown in Table 4.

·     Deletes all performance statistics for the task and recollects the performance statistics.

Examples

# Set the performance statistics interval to 5 minutes for performance statistics task task1.

<Sysname> system-view

[Sysname] performance-management

[Sysname-pm] statistics task task1

[Sysname-pm-task-task1] statistics interval 5

statistics enable

Parameters

task-name: Specifies a performance statistics task name, a case-insensitive string of 1 to 31 characters. The name must start with a letter or digit and can contain only letters, digits, and underscores (_).

Usage guidelines

	IMPORTANT: Deleting a performance statistics task terminates the task and deletes all performance statistics for the task.

 

Performance sampling and statistics collection are performed on a statistics task basis.

The device supports a maximum of 16 statistics tasks.

Execute the undo statistics task command with caution. The command terminates the specified performance statistics task and deletes all performance statistics for the task.

Examples

# Create a performance statistics task named task1.

<Sysname> system-view

[Sysname] performance-management

[Sysname-pm] statistics task task1

[Sysname-pm-task-task1]
