Getting started - agent not responding

CommunityUser — Tue, 20 Jun 2017 15:06:16 GMT

I went through the setup instructions for Tomcat and added the relevant lines to the setenv.sh script, and (hoorah!) I got the following when restarting Tomcat;

but "Waiting for Connection..." never actually ends, and I can't see anything else related in the Tomcat logs. Help?

We hope you have followed the suggestions as per docs link here

https://docs.appdynamics.com/display/PRO43/Apache+Tomcat+Startup+Settings

If yes, and still you face the problem, please send us details as listed here

1)Please let us know the exact problem you experience(Is application not starting or Is agent not reporting to controller or any other)

2)tomcat startup scripts wherever you have added java agent settings

3) Tomcat version

4) Zipped agent logs located under <agent-install-dir>/logs folder

Thanks

Rajesh

Hi Matt,

did you got chance to follow our agent SME suggestions, if yes, please share logs if this is still an issue?

Re: Getting started - agent not responding

CommunityUser — Thu, 22 Jun 2017 11:47:48 GMT

Instructions followed, you'll be glad to hear.

1) the agent is reporting to the controller - the getting started stays at "Waiting for connection", and doesn't go any further.

2) CATALINA_OPTS="$CATALINA_OPTS -javaagent:/home/ubuntu/appagent/javaagent.jar"

3) Tomcat version is

8.0.32-1ubuntu1.4

4) there is no logs directory, so no logs to send - the only thing I can send is the catalina.out containing the app agent information, which I included in the original, but here it is again (there is nothing else in the logs associated):

Please pass application, tier and node name as it looks like they were not configured. Please pass them in controller-info.xml file located under <agent-install-dir>/conf folder

Thanks for the reply! Can I suggest you add this to the getting started wizard as a tip? It might save you some extra questions in the forums 🙂 I'll try it and get back to you.
