I had a problem with weblogic wldf instrumentation.
I configured 2 instrumentation monitors for my app.
1st: a monitor 'servlet_around_service' with an action 'traceElapsedTimeAction'. It works fine. I can get events data through wls console and every record seems good.
2nd: a monitor 'servlet_before_service' with an action 'DisplayArgumentsAction'. While, I can get events data through wls console, but however the column 'arguments' of each record is empty. Question is how can I get out the http parameters(which a browser send to a http server through http get or http post)
