Icinga2 dependecies of devices on HA

Question

I would like to configure a Host-to-Host dependency on Icinga2, however, one of the Hosts has an HA configuration, so I need the to trigger it only when both HA devices are down. Suppose this scenario:

Let's say I have all these devices on Icinga2. It's clear that WAN switch has a dependency on both routers, so I want to avoid monitoring the WAN switch only if BOTH routers are down. I could not find anything like this on Icinga2 docs. Anybody has an idea of the best way to set this?

Answer 1

This behavior has been fixed in 2.3.10, so multiple host dependencies can exist. (https://dev.icinga.org/issues/10058)

There is a whole chapter in the docs: http://docs.icinga.org/icinga2/latest/doc/module/icinga2/chapter/monitoring-basics#dependencies

What you basically do two dependencies:

apply Dependency "behind-rtr1" to Host {
  parent_host_name = "rtr1"
  disable_checks = true
  disable_notifications = true

  // how ever you would specify that
  assign where host.vars.zone == "wan"
}
apply Dependency "behind-rtr2" to Host {
  parent_host_name = "rtr2"
  disable_checks = true
  disable_notifications = true

  // how ever you would specify that
  assign where host.vars.zone == "wan"
}
