&gt; will i need to pass the signoz backend hosted url and app-name in each of tomcat server’s setenv.sh file in all instances
The default URL is `localhost:4317` . You should make sure to configure the env `OTEL_EXPORTER_OTLP_ENDPOINT` to the SigNoz backend.

&gt; another way to inject otel agent without intervention of runtime environment
If you referring to they byte code injection, then no. that is how the auto instrumentation works.

okay srikanth , thanks for the clearification

Hi srikanth , i setted up signoz on ec2 instance , succesfully installed all docker images and continers are properly running but signoz portal is partially working as i m only able to see the ui components but no data in any of the component like services , traces , logs all sections are empty and always pop up comes with "something went wrong" , i enabled the required ports for all services that are running over docker but still no data is coming , can there be any possible other reason ??

Suddenly started getting "something went wrong " in my localhost too , unable to debug the issue !

What does docker ps show? Do you see query-service running?
