Open peppepetra opened 1 year ago

peppepetra commented 1 year ago

This is happening with grafana-agent ver 0.35.4 , snap rev. 16, channel latest/stable.

Node exporter is reporting following errors on logs while collecting processes metrics:

I have updated the bug since, since I've just realized that node-exporter is actually working. It is probably just failing to collect processes metrics.

I've deployed grafana-agent snap version 0.35.4, rev 16, from charm rev 65, still seeing these entries on dmesg and syslog output.

Related to canonical/grafana-agent-operator#52. We are currently making a classic confinement snap that should fix all of these issues.
