Agent Issues

Symptom

The kprobe agent is not ready or reports probe attachment failures.

Checks

kubectl get pods -n kprobe -l app.kubernetes.io/component=agent
kubectl describe pod -n kprobe -l app.kubernetes.io/component=agent
kubectl logs -n kprobe daemonset/kprobe-agent

Likely causes

unsupported kernel
missing BTF support
insufficient permissions
security policy blocks privileged agent
node selector or toleration mismatch

Fixes

confirm kernel version and BTF support
review Helm agent permissions
check Pod Security Admission or admission controller policies
schedule the agent only on supported Linux nodes
