Activating DEBUG Logging for AppDynamics Machine Agent

[Abhi.Bajaj]

Step-by-Step Guide to Enabling DEBUG Logs in Machine Agent

Debug logs for Machine Agents are important to help you understand issues and help you fix them.

• To enable, edit <MA-Home>/conf/logging/log4j.xml file.
• As shared in the screenshot, set the level = "debug"
  

  <Logger name="com.singularity" level="debug" additivity="false">
                <AppenderRef ref="FileAppender"/>
    
  </Logger>
    
  <Logger name="com.appdynamics" level="debug" additivity="false">
    
                <AppenderRef ref="FileAppender"/>
    
  </Logger>

• Once done, save the file
• The Machine Agent reads this file every few minutes so DEBUG logging will automatically take effect
• Once complete, logs can be found in the <MA-Home>/logs folder

But if MA is down and not able to coming UP then during offline also Machine Agent reads this file?

Hi Rakesh,

If MA Service is running then yes this file will be read. If MA service is down, it won't

When you start the service for the first time with DEBUG set, It will log the startUp in DEBUG
