Using http tools, we can find two dynatrace component from web page.
dynaTraceMonitor and dtagent_xxx.js
First we need to enable UEM feature.
The data will be sent back to your AppMon environment. We send them to dynatraceMonitor first.
The dtcookie contains 2 things the session id and the AppMon application information. This information is used to keep track of which requests belong to a visit and to enforce the "visit coverage" in case you do not want to capture all the visits.
NOTE: From dynatrace 6.1 the dynaTraceMonitor and dtagent_xxx.js can be renamed in the UEM configuration section of the system profile.
