While chasing Icinga alerts, I noticed that some of them would have been better as tasks than (ignored) alerts.
I don't know if it's possible to have warning open task and critical alert. If so the two bellow would be good candidates (and unknowns could be good ones as well as it usually mean something is wrong with the check itself).
- Disk space (warning)
- BGP status (warning)
- Long running screen/tmux
- Memory correctable errors -EDAC-
- mgmt SSH not working
- Hosts XXX is not in mediawiki-installation dsh group
I'd bet there are other alerts in the same case, maybe we can complete that list as they show up?
