Can you get the simple petclinc work in tomcat?

the reason I asked if you looked at this thread at the very end they finally figure it out they weren't using a supported framework. Are you using some other framework with your spring boot?

See [https://www.elastic.co/guide/en/kibana/6.6/apm-getting-started.html](https://www.elastic.co/guide/en/kibana/6.6/apm-getting-started.html)? If it still does not work, could you execute this query in the Kibana Dev Tools console: GET /apm\*/\_search { "query": { "match\_all": {} } }
