hi y'all ... i'm testing out this APM ... installed demo and now it says i'm on 15 day trials ... configured most stuff i needed for now (app agent and machine agent) ... my boxes are showing up on the controller.


But i'm not seeing any metrics at all ... and i keep gettings notification about this:


Agent license request denied. Agent type: sim-machine-agent; Host: server; Reason: License limit hit for controller


I have thrown the license file to the controller folder ... so not sure why i'm getting this flag and not seeing anything at my home dashboard.


any idea ... tia!
