Changing the sampling interval

You can change the sampling interval for monitoring. For example, if you want to collect statistics over a longer period of time, you can lengthen the sampling interval to increase the storing period (for details see Maximum storing period for monitoring).

Prerequisites

Required role: Storage Administrator (Performance Management)

Procedure

Display the Performance Monitor window.

In Device Manager - Storage Navigator:

Select Analytics in Explorer.

Select Performance Monitor in the tree to open the Performance Monitor window.

In Command Suite:

Select the Resources tab, and expand the Storage Systems tree.

Right-click the target storage system and then select Performance Monitor.

In the Performance Monitor window click Edit Monitoring Switch to open the Edit Monitoring Switch window.

Select the desired sampling interval in the Sample Interval. This option is available only when the current monitoring status is Enable.

Click Finish.

In the Confirm window enter your task name in Task Name, and click Apply to change the sampling interval.

Monitoring data cannot be displayed immediately after the sampling interval is changed, because no monitoring data with the new sampling interval has accumulated. “Immediately after” here means the time within the first two sampling intervals after the interval was changed. For instance, if the sampling interval is changed to 15 minutes, monitoring data is not accumulated for up to 29 minutes after the interval was changed.
