There are events that are not being captured by the APM Agent.
On CEM side we search in APMBD, and we find transaction sessions.
But on APM Agent side, we do not see any cross pounding transaction traces.
Release : 10.7.0
Component : APM Agents
Transaction traces on the agent side and the transaction sessions on the CEM side, are independent of each other.
There may be transaction traces on the agent side that Cross pounding to transaction sessions on the CEM side. There may not be transaction traces on the agent side that Cross pounding to transaction sessions on the CEM side.
APM Agent transaction traces works different. You may have transaction session or even an error/event on the application/CEM side, but APM Agent may not capture this.
One way you can test the issue is as follows.
On the agent side, start the manual transaction trace and then recreate the error/event on the application side.
If the agent captured the transaction trace, and shows you the error/event, then you can make additional adjustments on agent side base on what you find.
