AppD Java agent 4.4 with controller - will it work?

Joe .Ammann


we're currently using AppD and I just read the new release notes of 4.4. The Java Agent 4.4 would have 2 very important enhancements for my use-case

  • support for the Apache Async HTTP Client
  • enhanced support for Kafka (and Akka)

My question: will I be able to profit from these enhancement by just upgradeing the agent to 4.4, but leave the controller at Only a very small minority of the agents really need those enhancements, so I would like to upgrade only those few machines, and not the whole environment


CU, Joe

Hm, I guess I don't even need to try, the notes say


      AppDynamics agents are not backwards compatible with the AppDynamics Controller. The Controller version must be equal to or greater than the versions of any agents connecting to it.


No joy, I guess...

You're right Joe.

You'll need to upgrade your Controller to 4.4 before you can leverage the 4.4 agents.
