Starting monitoring

When you start monitoring a storage system, all of its previous monitoring statistics are deleted. If you want to keep the previous monitoring statistics, first export the desired data using Export Tool and then restart monitoring.

After you have set the storing period for the monitoring data, you can start the monitoring function. While the statistics information is being collected, the server workload increases and the client process might slow down.

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.

Click Enable in the Monitoring Switch field.

Select the sampling interval in the Sample Interval. This option is activated when you specify Enable for Current Status.

Click Finish.

In the Confirm window enter your task name in Task Name, and click Apply to start monitoring.

Monitoring data cannot be displayed for the time within the first two sampling intervals after the monitoring starts because no monitoring data has accumulated. For instance, if the sampling interval is set to 15 minutes, monitoring data is not accumulated for up to 29 minutes after the start of monitoring.
