JavaAgent start failed on Docker-Container

[Raphael.Lekies]

Hello together,

I created a Docker container with the Java AppAgent (4.5.0.23604) inside. Also I uncomment the line "<appender-ref ref="AgentLogAppender"/>" in the file log4j-unknown.xml and the line "<AppenderRef ref="Console"/>" in the file log4j2-unknown.xml.

The container started in a kubernetes environment.

Logoutput:

Full Agent Registration Info Resolver using node name [unknown]
Install Directory resolved to[/opt/appdynamics]
ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.

What am I doing wrong here?

With kind regards

Hi Raphael,
Nodename seems to be missing in the above code.
-Dappdynamics.agent.nodeName=<node name> This property seems to be missing when starting the Java Agent.
Could you try adding this property and running the code again. May be this could help.

Regards,
Megha
