Course: Elastic Observability Engineer On-Demand  
Version: 8.8.2  
Question:

Hello there!

I'm currently doing the Elastic Observability Engineer On-Demand course and I'm having some issues in Lab 3.2.

After setting up the Java agent for the Petclinic application core I do see the petclinic-java service in the list of APM services but no data is received.

This is what I added to the `/root/start-scripts/50-petclinic-server.sh` file of the docker image.

The PetClinic application is working fine and the docker image containing the server is running correctly.

After a while the petclinic-java service disappears.

Another thing I noticed is that the Service map is not what I was expecting it to be.

Am I missing something?

Best regards,

Francesco

Hi @cesco ,

have you restarted `petclinic-server` after adding the configurations?

You can restart it running: `docker restart petclinic-server`.

Best,  
Andre

Hi @Andre_Murbach_Maidl, thanks for the reply!

Yes, I did restart it after adding the configuration, and that's when the service appeared in the list, but no data was being received from it.

Best,  
Francesco
