Scope
A Configuration Tuning is a structured review of the settings and performance, with the goal of optimizing the capability of various components of your APM solution. This Configuration Tuning is focused on the ABA component of the APM solution.
The processes discussed are appropriate for client practitioners, pre-sales and services consultants. You will want to have a good understanding of using the APM Workstation: navigation, searches and management module editing. You should also have good skills in keeping track of your work with NotePad and SpreadSheet.
Duration
A Configuration Tuning may be completed in a few hours or may take a week or more, depending on the frequency that you can introduce configuration changes to the production environment, after some allowance for the metric stream to be re-established. As the ABA component is a subscriber to the metrics stream, production changes should be straightforward as no application or agent configuration is being impacted. Earlier versions may require a restart of the CA APM MOM but this is no longer necessary from APM 9.6 as the Analytics.properties files, which contains the ABA configuration, is now a ‘hot’ property.
Benefits
Completing a Configuration Tuning is important to the long-term success of an APM initiative and to ensure the intended operation of the ABA component. Tuning of the APM configuration is often a significant gap which you can help the customer overcome.
