Monitor Performance window

Use this window to specify the monitoring period and monitoring objects that will be displayed in graphs. You can set a maximum of eight monitoring objects per graph panel. You can set a maximum of four graph panels with up to 16 monitoring objects.

Data Range

Specify a range of statistics. Short-Range is default when there is monitor data collected with short range. However, Long-Range is default when there is no monitor data collected with short range.

  • Short-Range: Graphs are displayed according to the value specified in the Sample Interval field in the Edit Monitoring Switch window. You can specify the sampling interval from 1 to 15 minutes. The interval for measuring or storing the information depends on the number of CUs to be monitored.
  • Long-Range: Graphs are displayed 0, 15, 30, or 45 minutes on every hour.

Time Range

Specify the storing period of statistics

  • Set Range: Select this option to specify start and ending times to set a time range for which monitoring statistics will be collected.
  • Use Real Time: Select this option to view statistics in real time mode, where statistics are updated at the value of the Sample Interval you specify on the Edit Monitoring Switch window. This option is available when the Short-Range mode is selected. When this option is selected, you cannot change the date field in the Set Range option.
