Capturing User Principal in EUM or Browser_Records or Web_session_Records

[Divakar.Vengataraman]

Hi,
I am new to AppDynamics and analysing few things to capture the user data. Could you please help me with the below queries.

1) I am able to instrument Transactions to capture User Principal. But Is it possible to instrument / configure AppD to capture User Principal in Browser_Records or Web_session_records ?

2) Is it possible to capture application generated Session ID rather than AppD generated ID in  Browser_Records or Web_session_records ?

3) Is there any co-relating / mapping fields between Transactions table and (Browser_records, Web_session_records) table ?

4) Does Dexter output contains only APM data? Is it possible to retrieve Browser_records, Web_session_records data using Dexter ? 

Please advise.

Thanks.
