Capture userid from apm for dcrum

Hello,

 

We need to configure username detection rule in DCRUM (Application performance monitoring tool). For that we need to capture the session variable value.

 

We would like to know when user provide its credentials to F5 Authentication page and forward that request to WebServer. Please refer below the format in which we need to configure this username detection rule.

 

 

Please advise how can i go ahead with this

 

Regards Pooja
