I am running with scheduled maintenance on my setup, and every night I have 8 DRAC cards reboot and have a maintenance window set in LibreNMS. This being the case, the system still pages even with the devices in maintenance. I’m not sure if I have a misconfiguration, everything appears to be correct.
When it hits the scheduled time, it does show maintenance mode for the device. The problem does not reproduce under manual scheduled maintenance, only under repeating scheduled maintenance.
I’ll try and replicate this to see if maybe its a bug from the newer librenms version. Which alert transport you using that’s sending out comms during the scheduled maintenance?
I’ve just tested with a single device and was unable to replicate. Using Email, Teams and browser push via a Alert Transport Group.
I put a device into scheduled maintenance, shut the network to it, LibreNMS reports its down and the alert capture shows it matches the ‘Down’ alert but no alert transport was triggered.
We’re also experiencing this with a group of devices that are covered under scheduled maintenance. The issue seems to have only been occuring since the tail end of last year.
