Hi Winkle,
the Average Response Time CA APM is reporting is usually that of a component, mostly on the application server, e.g.:
- Frontend Average Response Time is the response time of the application (server), from http request received to response sent.
- Backend Average Response Time is the response time of a backend, e.g. database or web service.
- Servlet Average Response Time is the response time of the call to the service() method of the servlet.
- Most other Average Response Times are that of a method of a component similar to the servlet example.
If you use CEM (Customer Experience Monitor) and/or BRTM (Browser Response Time Monitor) you can also measure response time in the network and on the client.
The best way to achieve the breakdown is to use BRTM: then you get a breakdown from the client perspective and can mix in the server response time.
Ciao,
