fix: downgrade matchContainerID error log to debug level

michaelfindlater · claude · michaelfindlater · commit d8f6e6be5e7b · 2026-03-16T14:21:52.000+09:00
The getKubernetesPodMetadata function iterates all containers on a
node to find the one matching a profiled PID. Non-matching containers
are expected - logging each at Error level produces N_processes *
M_containers error logs per profiling cycle.

Downgrade to Debugf to match the level already used in
addPodContainerLabels for the same matchContainerID error.
