Discuss Cisco 500-420 Exam Topic 3 Question 53

Developers and operations personnel complain the Controller tracks many irrelevant Java classes and methods. How does a Performance Analyst exclude this unhelpful information?

AConfiguration > Baselines and create a new dynamic baseline

BEdit the mbeans-server.xml file to delete the irrelevant methods

CConfiguration > Instrumentation > Call Graph Settings and exclude irrelevant packages

DEdit the controller-info.xml file to exclude irrelevant methods

Suggested Answer: C

To streamline the monitoring process and enhance the relevance of collected data, AppDynamics allows Performance Analysts to exclude certain Java classes and methods from instrumentation. This is done through the 'Configuration > Instrumentation > Call Graph Settings' menu, where irrelevant packages and classes can be specified for exclusion. This approach prevents the AppDynamics agent from tracking unnecessary or irrelevant methods, thus reducing overhead and focusing on the most critical aspects of application performance.

AppDynamics documentation on Call Graph Settings: This section details how to configure call graph settings, including the exclusion of specific classes and methods from instrumentation, to optimize performance monitoring.

Wait, can you really edit mbeans-server.xml? Sounds risky!

I'm leaning towards A, but I wonder if creating a new dynamic baseline is really the right approach for excluding irrelevant methods.

I feel like I've seen a similar question where we had to exclude certain classes, and I think it was related to instrumentation settings.

I remember something about editing configuration files, but I can't recall if it's mbeans-server.xml or controller-info.xml.

I think the answer might be C, but I'm not entirely sure how the Call Graph Settings work in that context.
