According to the Data Collectors document1, a data collector is a configuration that captures application data from a method invocation or an HTTP request. A data collector is associated with a specific method signature or an HTTP parameter name. Therefore, if a new class and method have been deployed to the application, or a new method parameter has been added to an instrumented class, the existing data collector may not match the new code and may need to be updated. However, if the business transaction has been deprecated, or a new HTTP parameter has been added to an existing business transaction, the existing data collector may still work as expected, unless the data collector is specifically configured to filter by the business transaction name or the HTTP parameter value. References:

According to the Java Memory Leaks document1, one of the ways to detect and troubleshoot Java memory leaks is to use the Automatic Leak Detection feature on the Memory tab of the Node Dashboard. This feature captures and analyzes the collections that are actively used and growing in size over time, indicating a potential memory leak. You can also drill down into the leaking collections to see the content summary and the access traces that show the code path and the business transactions that access the collection. Therefore, the correct answer is D. Examining the values on the Server tab, configuring Object Instance Tracking, or verifying and adjusting the Memory Monitoring configuration may not directly reveal the source of the memory leak, but they may provide some useful information or metrics to support the diagnosis. References:

To confirm that the agent is communicating properly to the controller, you can use the following methods:

• Check if data is being written to the agent log in /logs. This indicates that the agent is able to send metrics and events to the controller. You can also look for any errors or warnings in the log file that might indicate a connection issue1
• Select Application > Tiers and Nodes > Look for the Node. This shows you the list of nodes that are registered with the controller and their status. You can see if the node is up or down, the agent version, the last reported time, and the machine name2
