You can use Root Cause Analysis (RCA) to filter a set of events to determine the cause of a higher level system, service, or application problem. RCA can help you to eliminate apparent performance problems that may otherwise appear to be root causes but which are only side effects or symptoms of the actual root cause of the problem, allowing you to more quickly identify problem areas. You can view the RCA results on the home page or topology page of any service that is currently down. The topology page allows you to see a graphical representation of the service, system and component dependencies with the target(s) highlighted that RCA has implicated as causing the service failure.
Use the Root Cause Analysis Configuration page to define how RCA is run. By default, RCA is run automatically whenever a service fails. You can disable RCA by changing the default Analysis Mode to Manual.
Root Cause Analysis can be performed automatically or manually each time a service fails. If performed automatically, the system will analyze the critical components of the service for causes and then update this analysis as the state of the service and its components changes. You can disable RCA by setting the analysis mode to Manual. If you choose to perform the analysis manually, you can perform the analysis from the Service Home page at anytime by choosing Perform Analysis if the service is down.
Note: When you initiate RCA manually, RCA does not store the results for you, thus providing no history for later reference.
The Configuration page lists the component tests defined for the service. By default, Root Cause Analysis considers a key component's availability status to determine whether or not it is a cause of service failure. If the key component is unavailable, or if any of your component tests conditions are not met, then this component will be considered a cause of the service failure.
Click the link in the Component Tests column of the table for the key component you want to test. You can manage component tests for the service by using the Component Tests page and adding, removing, or editing tests.
