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.
- But here I only see the machine agent process, and no other processes
- Is it capturing the details of its own container only or for the whole pod?
And If I go to the Tiers & Nodes of my application:
- There are no details under Servers there.
- Also, the machine agent status is "Agent not installed" under the Agents tab for each node.
So it looks like the machine agent is not able to detect the nodes of my application or not able to attach to them.
