Nagios Support Forum

Hi,

We currently have one Nagios Monitor checking services/hosts on our infrastructure. However, it seems maybe once or twice a week we receive false notifications of our hosts going into a down state.

We think this may be related to our VPN perhaps timing out thus getting no return on the host checks, and having the hosts appear offline (our Nagios Monitor is in a different office than our monitored servers).

I know you can set up multiple Nagios Monitors, but from what I've read, the second one will pick up if the first monitor service fails for whatever reason.

My question is, is there a way to set up a second monitor, in a different location from the first, but only receive notifications if both monitors' service/host checks fail? (i.e. notification if monitor1 and monitor2 fail checking host1, no notification if monitor1 fails check for host1 but monitor2 check is ok for host1)

Short answer: no, there's nothing floating around that I am aware of to make a set up like that, not unless you are in the mood to write some custom event handlers that manage the interaction between the two nagios systems.

You might just be better off putting the Nagios server at the remote site?

Thanks!

You could use an OSCP command to push passive results to the 2nd server, and then set a freshness threshold on the 2nd server so that if the data was stale, it would run an active check against the host. There's some setup involved in that, so it could just be easier to have a second Nagios install.
