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
