Setup Elastic APM for the first time

Hi @stephenb, i'm excited to join the community...

I've already done troubleshooting regarding APM. Here's what i've done
I deployed springboot test app with petclinic from github

and getting the responses from Kibana -> APM-> Services interface

java -javaagent:/home/weblogic/source/elastic-apm-agent.jar -Delastic.apm.service_name=PetClinic -Delastic.apm.application_packages=org.springframework.samples.petclinic -Delastic.apm.server_url=http://172.70.12.30:8200 -jar target/*.jar

I'll try to deploy your test app soon, Thanks!
