I found this in the tomcat startup log

How to provide the service name with JAR?

23

See the configuration documentation. You can, for example, add an elasticsearch.properties file in the same folder as elastic-apm-agent.jar.

24

The issue is resolved now I can read both .JAR and Tomcat data in kibana. Below is the snapshot from Kibana. The reason Tomcat was not reading the data was because service_name was not defined. Thus elasticapm.propertiesfile You can place aelasticapm.properties` in the same directory the agent jar resides in, is mandatory configuration.
