Description of the problem including expected versus actual behavior. Please include screenshots (if relevant): I want to trace PHP and mysql calls - but service map only shows PHP and says it will show other connect services or external requests if we can detect them.

Steps to reproduce:

1. Install ElasticSearch, Kibana, apm-server to latest version
   2.Configure PHP agent to talk to apm-server
2. Load up /app/apm/services
3. Select service
4. Select Service Map

Errors in browser console (if relevant): N/A
