Set the Correlation Auto-Extend Time

In this task, you learn how to set event correlation to automatically extend the correlation time window whenever an additional symptom is correlated to the same cause. Each time that an event is correlated with a problem, the time period set in the correlation time window is restarted to help enable the correlation of a greater proportion of symptoms associated with the original event.

Note For information on button actions, see Correlation Rules User Interface.

To set Auto-Extend for correlation rules:

Open the Infrastructure Settings manager:

Administration > Setup and Maintenance > Infrastructure Settings

Alternatively, click Infrastructure Settings.
In the Applications list, set the context to Operations Management.
In the Topology-Based Event Correlation Settings section, click the Edit Setting button for the entry: Auto-Extend Time Window Mode.
In the Edit Setting dialog box, set the Value to true.
Select Save to apply the new time setting immediately.
