3 Performance Monitor data
This chapter provides detailed descriptions of the monitoring data collected and displayed by
Performance Monitor.
Monitoring data
The following table lists the objects that can be monitored and specifies the data that is collected
for each monitoring object. The monitoring data for each sampling interval is the average value
of the data over the data sampling interval. For instructions on viewing the monitoring data, see
“Using the Performance Monitor data graphs” (page 21) .
The monitoring data shows the average value of the sampling interval. The sampling interval is 1
to 15 minutes for Short Range and 15 minutes for Long Range. The monitoring data shows the
information by each resource ID even when the volume is in a virtual storage machine (not by
virtual ID).
