4.4 Support methodology for root cause investigation when an error or warning is displayed for a monitored service
When an event, such as an overage of a threshold or a trend leading to an overage of a threshold, is detected in a monitored service, you can use ITSLM to investigate the cause.
This section discusses what you can do when you use ITSLM for root cause investigation and explains the procedures.
ITSLM enables you to do the following to determine the cause of an error or warning:
-
Check the timing of the event that caused the error or warning
-
Check past service performance
After you have handled the error or warning, you can check whether the monitored service's status has returned to normal.
If you link ITSLM with Performance Management, you can check not only the performance of the monitored services, but you can also check the systems that are providing the monitored services, such as hosts and middleware, for the causes of errors and warnings.
