Unable to start the Appdynamics server agent

[Poorvitha.P]

Hi,

The start-up script for the spring boot application is like this java -javaagent:/opt/jeppesen/crew-leave/Appagent/AppServerAgent-ibm-22.2.0.33545/javaagent.jar -jar /opt/app/app.jar.

The AppDynamics log shows that the app agent is created successfully. But nothing is getting captured.  Also, under agents, I see that the uptime is 0%. This is for a Linux server.

I get a few warnings at the end

Hi @Poorvitha.P,

Have you been able to check out the Java Agent Docs pages? If not, please check them out here - https://docs.appdynamics.com/22.2/en/application-monitoring/install-app-server-agents/java-agent

Do let me know if these helped you out.

Followed the steps but, it did not help much. In the logfile it says succesfully installed but i dont see anything getting captured. In the controller UI the agent uptime says 0%. It is a spring boot application in docker environment.

Was able to successfully configure appdynamics. 

- There was a small change in the startup file that was made. For spring boot application,

java -javaagent:/usr/local/Appagent/AppServerAgent-1.8-22.1.0.33445/ver22.1.0.33445/javaagent.jar -jar /opt/app.jar

- The version of JAVA_HOME was different from what the application was using. Appdynamics takes it from JAVA_HOME and so there was a mismatch. Changed the JAVA_HOME settings. 

- Got errors "saas.appdynamics.com:443 failed to respond". Updated the controller-ssl-enabled to true.

Is there a way to update the java path for appdynamics in config file?
