Hi Prashant.Mhatre

the agent will need a few configuration parameters, especially connection details, to initialize properly.

https://docs.appdynamics.com/display/PRO45/Install+the+Java+Agent#InstalltheJavaAgent-AttachingtheJavaAgenttoaRunningJVMProcess

Are these set ?

Thanks

Philipp

Hi @Nitesh.Kewat,

You are a partner and should be on a paid account, not a trial license. Can you confirm if this is true or not?
