[Nagios-users] 2 Nagios boxes running together in different locations
Hi all, We run 1 nagios box in our Office at location A - this monitors all servers/websites etc in Location A and a remote office in Location B hooked up with a static VPN We have a bit of a tempermental firewall at the moment that keeps going down thus resulting in everything appearing down to Nagios in Location A and it alerting like a loonatic for all hosts/services (88/156) So question is: Can I put a second nagios box in Location B as some sort of slave - and have it cross reference nagios box in Location A and only alert if both boxes agree that said host(s)/service(s) is/are in down state? If so are there any guides/helps out on the www that will assist in this setup?

We have a bit of a tempermental firewall at the moment that keeps going down thus resulting in everything appearing down to Nagios in Location A and it alerting like a loonatic for all hosts/services (88/156) You could monitor the firewall, and configure it to be the parent of the hosts behind it.

Re: [Nagios-users] 2 Nagios boxes running together in different locations
I would agree with this as well, usually easier I think then trying to cross-connect everything together and make sense of all of it. Make them standalone, and then use something like Multisite which can bring all of them together in one view so it all appears to be one box setup.
