You can test impact analysis rules when you are creating or modifying a rule
and want to make sure that the rule works as intended. For example, you might have run the impact
analysis engine, and it did not identify a known impact that is based on your CMDB settings. You can
create a rule to ensure that the impact is identified, or modify the rule that is used for this
relationship. Testing the rule ensures that the impact is correctly identified.
About this task
Perform the following steps to test a new rule:
Procedure
- In the Test Impact Analysis Rules section, click Arrow icon at the
CINUM ID field, and select a CI for which you want to calculate
impacts when the CI goes offline.
- Click Test Rules. The impact analysis engine runs the rules to determine where the
matches are, so that you can see whether the specified aspect of the rule matched as intended. The
Relationships section displays a list of all of the relationships that contain the specified CI.
After you run the test, the following information is displayed:
- The Relationships section displays a list of all of the relationships that contain
the test CI. For each relationship in the list, the source CI, the relationship name, and the target
CI are displayed.
- When you select a relationship in the Relationship section, the Impact Details
section displays a row for each rule that applies to the relationship. For an impact to be
identified, all of the data values in a rule, including the SOURCE value, the TARGET value, and any
conditions that are defined for the rule, must match. An impact might or might not have been
identified.
