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.
By default, Root Cause Analysis considers the availability of key components to determine whether or not they are causes of service failure. You can specify additional conditions, or component tests, for Root Cause Analysis to consider. 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.
Use the Component Hosts Test page to also define tests on the host(s) where any key component resides as well as on the components themselves.
To create a test for the host of this key component, click Add to select a metric and set the threshold conditions for failure.
