Simple setup, I need to see how I can monitor tomcat application server using APM
My elasticsearch server, kibana, apm server works fine, did the necessary changes in catalina.sh
CATALINA_OPTS="$JPDA_OPTS $CATALINA_OPTS"
export CATALINA_OPTS="$CATALINA_OPTS -javaagent:/home/itsupport/elastic-apm-agent-1.9.0.jar"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.service_name=my-tomcat"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.application_packages=org.example,org.another.example"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.server_urls=http://localhost:8200"

I have kept the "elastic-apm-agent-1.9.0.jar" , in the correct location as specified
My Issue
my APM client not connecting to the APM server, or I am not aware on which logs to check for APM client .
On the kibana server I am getting message
No data has been received from agents yet, while checking for agent status

Request guidance on trouble shooting the apm client part for tomcat,
Thanks

Hi Joseph,

If you are not seeing anything in your application logs, your script configurations are probably not applied. Validate your startup routine.

BTW, using -Delastic.apm.application_packages=org.example,org.another.example is wrong, unless your application packages are indeed org.example and org.another.example...

Good luck,
Eyal.

Thanks Eyal
You are right, my script configuration are not applied, I tried the same with JBoss in another instance and I am getting status back at Kibana.
So I have not done the correct settings for tomcat
About

-Delastic.apm.application_packages=

I will get rectify it and update in the forum
Thanks
Joseph John
