Introducing a Time Delay
As mentioned previously, Incident Manager RCA is an iterative process whereby incoming target down events are continually being evaluated, resulting in updates to causal analysis states. Over a period of time (minutes), a root cause may or may not remain a root cause depending on incoming target down events. The original target down event may later be classified as a symptom. To allow time for target down events to be reported, analyzed, and then acted upon (such as creating an incident), you can define an event evaluation time delay when creating a rule set.
In the previous example, where incidents are created for non-symptom events, without a time delay in the rule, there could potentially be an incident created for a non-symptom event that eventually becomes a symptom.
To add a time delay to the rule:
- From the Create Rule Set wizard Add Actions page, click Add or Edit (modify an existing rule). The Add Conditional Actions page displays.
- In the Conditions for Actions region, choose Only execute the actions if specified conditions match. A list of conditions displays.
- Choose Event has been open for specified duration.
- Specify the desired time delay.
- Click Continue and complete the remaining steps in the wizard.
