Additional Information

1. Specify the fully qualified class name, method name, and/or method arguments in the agent configuration profile to define a method. 2. Make a backup of default agent profile before editing. 3. Restart the instrumented application servers after editing the instrumentation configuration (agent/instrumentation.config) in order for the changes to take effect. 4. These settings are valid only for FullDetail and ComponentDetail Instrumentation Levels. Changing the values will have no effect if the Instrumentation Level is BasicDetail or NoDetail. The instrumentation level can be still set on the General page of the Configuration Category Editor for the agent instrumentation profile.
