Already testing it, once i get more results i’ll update Icinga2 at large scale topic for big environments.
Also i’m missing documentation about HighAvailability setup for each deamon in Icinga 2.12rc (icinga-core feature icingadb / redis / icingadb). if i have 2 masters i’m not sure by what principle they are updating redis(i have local redis without ha on each master), both in parallel or only the primary master.
In https://icinga.com/docs/icingadb/latest/doc/01-About/ following statement not documented:
Icinga DB also supports reading from multiple environments and writing into a single MySQL instance.
It would be nice to get little bit more info about this feature
