sample-interval

Function

The sample-interval command configures the sampling interval for a performance statistics task.

The undo sample-interval command restores the default setting.

By default, the sampling interval varies with the performance statistics interval as follows:

If the interval at which the performance statistics are collected is 5 minutes, the default sampling interval is 1 minute.
If the interval at which the performance statistics are collected is 10 minutes, the default sampling interval is 2 minutes.
If the interval at which the performance statistics are collected is 15 minutes, the default sampling interval is 3 minutes.
If the interval at which the performance statistics are collected is 30 minutes, the default sampling interval is 5 minutes.
If the interval at which the performance statistics are collected is 60 minutes, the default sampling interval is 5 minutes.
If the interval at which the performance statistics are collected is 1440 minutes, the default sampling interval is 15 minutes.

Usage Guidelines

After the statistics task is configured, the system collects statistics at a specified sampling interval. The shorter the sampling interval, the more accurate the statistics. However, more system resources are consumed.

Example

# Set the sampling interval to 5 minutes.
