Viewing periodic exceptions

This topic describes how to view periodic exceptions.

When a periodic exception occurs that is outside of the specified warning or problem threshold, you are informed in the following ways:

  • An entry is added to the Event Exception Log pane of the Exception Processing window.
  • A warning icon (Warning icon) or a problem icon (Problem icon) appears:
    • Next to the affected counter in the window that contains this counter.
    • In the folders pane of the System Overview window, next to the DB2® subsystem that contains the affected counter and next to the folders that include this DB2 subsystem.

    A problem icon overrules a warning icon. No icon is shown for counters that are listed in a table.

    When you move your mouse pointer over the counter, hover help shows the timestamp of the exception. If this counter is on a KPIs page of the System Overview window, hover help also contains the defined warning and problem thresholds.

    The icon disappears after the counter value falls below or above the threshold or you stop periodic exception processing and after you refresh the data. In the System Overview window, you need not refresh the data.

  • An entry is added to the 100 Most Recent Exceptions pane of the System Overview window.
  • A message is displayed, a sound (beep) is played, or both, if you specify this kind of notification in the Exception Settings window.

You can get more information about a periodic exception from the Periodic Exception Log pane of the Exception Processing window and the 100 Most Recent Exceptions pane of the System Overview window. In the Periodic Exception Log pane, click the exception and then:

  • Click Selected > Current Statistics Details to see the corresponding Statistics values.
  • Click Selected > Field Exception History to see a log of the exception values for the counter.
  • Click Selected > Thread Identity to see information about the application causing the exception.
  • Click Selected > Current Thread Details to see thread information. (This is available only if your OMEGAMON® Collector supports this function.)

In the 100 Most Recent Exceptions pane, right-click the exception and select the information you want to see.
