Monitoring data
The following table lists the objects that can be monitored and specifies the data that is collected for each monitoring object. You can specify the objects that are displayed in the graphs in the Performance Objects in the Monitor Performance window. When the resource group feature is installed, you can specify the objects to be displayed in the graphs only when the resources that are shown in the necessary resources in the following table are allocated.
The monitoring data for each sampling interval is the average value of the data over the data sampling interval. The sampling interval is 1 to 15 minutes. The monitoring data shows the information by each resource ID even when the volume is in a virtual storage machine (not by virtual ID). For instructions on viewing the monitoring data, see Using the Performance Monitor data graphs.
