Hi Support, 

I am a new user for AppDynamics. 

I had installed Controller and Java Agent in the same machine. And, added agent java options and restarted the JVM. 

The agent log had showed "Started AppDynamics Java Agent Successfully." message. 

But, the agent didn't connect to controller. 

In Agent log, we saw below error :

Hi,

Try and change your config file with controller host instead of localhost. Not sure wheather you can install agent and controller on samemachine.

Give a try with the  above changes.

Regards,

Pooja
