SigNoz Not Collecting Pod Logs Issue

TLDR Maksym is experiencing issues with SigNoz not collecting pod logs. Prashant suspects it could be an issue with the kubelet stats receiver and not pod logs.

I don’t think it’s the pod logs the issue with. But rather the kubelet stats receiver.

This issue is known to happen for DOKS.
Are you using Digital Ocean?

Which cloud vendor or tool are using for setting up your k8s cluster? Is it Digital Ocean?

The one who created the K8s cluster can help with that info.

It looks like K8s on Fedora CoreOS. Perhaps with CRI-O as container runtime.

I am not sure how well OpenTelemetry would work on that with defaults.
