Changing the expiry time for related events groups

Edit online

You can modify the expiry time for Active related events groups. When the expiry time is reached, the expired groups and related events display in the View Related Events portlet, within the Expired tab.

About this task

Groups that contain an expired group or pattern continue to correlate. The system administrator should review the group and expired group or event.

By default the related events expiry time is 6 months. Complete the following steps to change the related events expiry time.
Note: Watched related events groups do not expire.

Procedure

  1. Log in to the Netcool®/Impact UI.
  2. Select the Related Events project.
  3. Select the Policies tab.
  4. Within the Policies tab, select to edit the RE_CONSTANTS policy.
  5. Within the RE_CONSTANTS policy, change the value for the RE_EXPIRE_TIME constant. Enter your new value in months.
  6. Save the policy.

Results

This change takes effect only with newly discovered related event groups in the Active tabs.

What to do next

If you want to configure the expiry time so that deployed groups never expire, change the value for the RE_EXPIRE_TIME constant to 0 and save the policy for this change to take effect. You do not need to restart the Impact Server.

If you want to enable the expiry time at any stage, set this variable back to a value greater than 0.
