Hi, I am running multiple war files in single tomcat server. Had a doubt if we set the following property at tomcat level how will we differentiate at application level. set CATALINA\_OPTS=%CATALINA\_OPTS% -Delastic.apm.service\_name=my-cool-service Regards, Bryce Fernandes. ---

Thanks for the question. As described in the `service_name` config [documentation](https://www.elastic.co/guide/en/apm/agent/java/current/config-core.html#config-service-name), service names are auto-discovered by default (meaning - when the config option is not set). This should produce a service per war file. Please make sure you use the latest version, as the former had a bug that may affect this capability. Also notice the described caveat - the Metrics tab will not show metrics per service, instead you can view the JVM metrics under the default `tomcat-application` service. ---
