Cluster Agent node name environment variable not found

Hi Community,

I provision cluster agent with auto instrument, cluster and nodes information is showing up correctly in the controller. In clusters Pods, Inventory and Events show the correct information.

But the application is not auto instrumentating and I found these error logs in cluster agent pods. Could you guide me on what the cluster agent looking for?

Hi @Chanon.Wonglertniran,

I found this information. Please let me know if it's helpful.

Make sure this is no mismatch between the operator and cluster-agent versions.

This AppD Docs page might also be helpful.

After match cluster operator and cluster agent compatibility those error logs disappear.
