Hi @Jagan.Rajendran,

I saw the extension is having issues with newer versions of the Machine agent. Can you try downgrading to 20.11 and see if it works for you then. Please let me know if that helps out.

Thanks Ryan!

it's working perfectly.

Hi @Jagan.Rajendran,

I also just spoke with a coworker and it seems the latest version of the RabbitMQ Extension does support the latest Machine Agent. 

You can check the Extension page here for more info: https://www.appdynamics.com/community/exchange/extension/rabbitmq-monitoring-extension/
