I have a spring boot application, deployed in AKS. I use Appynamics docker image to inject the agent into JVM via init-container. My company does not have a cluster license, and I'm unsure if or when that would be available. But the Machine Agent and Server Visibility licenses are there. So to capture server stats, I'm trying to configure the machine agent using the sidecar container approach. Below is the snippet of my deployment file

I can see that the machine-agent container gets registered successfully and I can see the machines under Servers.
And If I go to the Tiers & Nodes of my application:
So it looks like the machine agent is not able to detect the nodes of my application or not able to attach to them.

Hi Sandeep,
This is a bit of a 2 part-er...
Firstly, If you have SIM licenses available, you're golden! As they also apply as the necessary license needed for the cluster agent. With this clarification, I'd say skip this work-around approach you're doing and just install the full cluster agent(s).
Please refer to the below docs:
After that, if you are not seeing things in the correct places in the controller. Ryan's instruction to submit a support ticket would be the next step.
Thanks,
Christopher
