Error / Incident
A systemd unit has been down on a host for a long time.
Debugging
This is quite a generic alert, so there's many options, but some things to try:
- Try to ssh to the host and check the status of the unit:
systemctl status <unit_name>
- Check the logs for that unit:
journalctl -u <unit_name> -n 1000
From there you might have to go to the specific service details on how to debug them.
- Ask on irc if someone is taking any action and forgot about it
- Check SAL (or sal.toolforge.org) for host being rebooted/taken down
- Check Netbox to make sure the host is not being decommed or network changes were not applied
- Check puppet for recent changes that might have affected the node
