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:

To examine the Java App agent logs on a host without login access, you can use the Controller UI to request the agent logs. This feature allows you to download the agent logs from the Controller UI without having to access the host machine. You can specify the log level, the time range, and the file size limit for the logs12 References: 1: Request Agent Logs 2: Java Agent Logging

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
