I have setup and configured ICINGA2 server on Ubuntu 16.04 LTS. I added majority of my hosts (mainly Windows hosts) and I noticed that sometimes ICINGA2 shows wrong hosts status for a while (1 minute or so). For example plenty of my hosts are DOWN status but I know that all hosts works properly all the time, and after next check interval hosts change their status to UP in ICINGA2.

Does anyone know why ICINGA2 monitoring system shows wrong host status?

  • I suspect IDO. Icinga need to refresh status in it sdatabase. When you use icinga-classic CGI, it update like a charm - it reads Icinga status from files. However using Icingaweb2 needs IDO and the database looks stale for a while (even minute in some large deployments). – Věroš K. Jan 22 '18 at 09:21
