Hi all, Last night we did a yum update on our Icinga2 host which rebooted the host at 01:03. At the point of reboot Icinga2 sent three host down alerts with "Additional Info: CRITICAL - Network Unreachable" for three different hosts. The issue is these hosts very unlikely did not go down at all as they're core network switches. Frustratingly looking at the affected hosts in IcingaWeb2 there's no record of these notifications even being sent. Is there anything we can do to try and retrospectively work out why these notifications were sent out, and also deduce why notifications weren't logged properly?
