Chapter 3 Operations of Performance Monitoring Function
Figure 3-17 Set Threshold Dialog (When displayed by selecting a line)
When you specify a threshold value in the [Set Threshold] area and click the [OK] button, the value is set as a
threshold and the dialog box closes. If the value of the item for which the threshold has been changed is
exceeding the threshold, the threshold exceeding state is cleared and the monitoring of the threshold resumes with
the new threshold. On the other hand, when you click the [Cancel] button, the values specified in the [Set
Threshold] area are ignored, and the dialog box closes without changing the thresholds which had been registered
when the dialog box opened.
Furthermore, when you specify multiple cells in the list and select [Set Threshold], the Set Threshold dialog box
appears. If the component type on the original screen is disk array, the thresholds of the selected monitored
items for the selected disk array can be changed simultaneously. If the component type on the original screen is
port, logical disk or physical disk, the thresholds of the selected monitored items for the selected monitoring
targets (all the logical disks, etc.) in the disk array specified in the combo box of the original screen can be
changed simultaneously.
Thresholds are centrally controlled by the iSM server. If different thresholds are set for the same monitoring
target from multiple clients, the threshold most recently specified becomes effective. Therefore, pay careful
attention to the settings.
