Evaluating and Modifying Thresholds
78 OMEGAMON II for DB2 User’s Guide: CUA Interface, Version 540
Evaluating and Modifying Thresholds
When you investigate a yellow or red status light from the System Status panel, you may
determine that the threshold values that caused the exception to trip did not really
indicate a problem in your DB2 subsystem. In this case, you need to change the current
threshold values for the exception to values that are appropriate for your site.
Displaying all exceptions
To display a list of exceptions and their threshold values for a monitored object on the
System Status panel:
■
Select a monitored object with the L (Control) action code, and press Enter.
Result: A pop-up window appears, which contains the exceptions and the threshold
values associated with the object. In this example, the Active Threads Thresholds
panel is shown.
Modifying thresholds
To modify any threshold or status setting on a thresholds panel:
■
Move the cursor to the field you want to change and type in the new value.
Result: The Save Profile Confirmation pop-up appears. You can choose to save the
new setting for this session only or you can save them to a profile.
