Sampling interval for monitoring

The sampling interval is the length of time between data collection events for monitoring. The number of CUs to be monitored determines the options for setting the sampling interval:

• Up to 32 CUs. If there are 32 or fewer CUs to be monitored, you can set the sampling interval from 1 to 15 minutes in increments of 1 minute. For example, when the sampling interval is set to 3 minutes, Performance Monitor collects statistics once every 3 minutes.

• Performance Monitor collects statistics for 1 day when data is collected at 1-minute intervals.

• Performance Monitor collects statistics for up to 15 days when data is collected at 15-minute intervals.
