Hi everyone, I am having issues in monitoring a java application inside a tomcat. I am monitoring the tomcat with a java agent and i see everything correctly. But when i install an application on it it seems that i can't monitor it correctly. I don't see business transactions (only the one related to the tomcat) i see only throughput. Is this normal? Am i missing something? Thanks in advance for your help! ---

Welcome to our community! 😃 It's not clear what this has to do with Kibana. What java agent are you using? ---

Hi, I am sorry if i put my question in the wrong topic. I am using the "observability -\> APM " that i found in Kibana so i thought it was a kibana question. I am using the Elastic Java agent, the one found here : [APM Java Agent Reference [1.x] | Elastic](https://www.elastic.co/guide/en/apm/agent/java/current/index.html) Hope i explained myselft better! Thanks for the answer! ---

Hi @Nigmur, did you see docs [Manual setup with -javaagent flag | APM Java Agent Reference [1.x] | Elastic](https://www.elastic.co/guide/en/apm/agent/java/current/setup-javaagent.html#setup-tomcat)? What version of tomcat do you use? Do you use supported technologies in your application? [Supported technologies | APM Java Agent Reference [1.x] | Elastic](https://www.elastic.co/guide/en/apm/agent/java/current/supported-technologies-details.html) And what version of elastic-java-agent do you use? ---

@Nigmur, Did you configure `export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.application_packages=org.example,org.another.example" ` ? ---

Hi, We installed the tomcat as a service and in the tomcat.service properties we have this line: ``````````````````````````````````````````````````````````auto Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC -javaagent:/opt/elastic-apm/elastic-apm-agent-1.22.0.jar -Delastic.apm.service_name=T omcat9 -Delastic.apm.application_packages=org.apache.catalina -Delastic.apm.server_url=http://10.1.0.27:8200' ````````````````````````````````````````````````````````` Thank you! `````````````````````````````````````````````````````````` ---
