Re: [Nagios-users] Redundant Nagios setups...
As you already have *BSD installed as base server for nagios, and you need an mechanism when one machine is down, second to take its rolle and all happy. I would recommned to take a look into CARP http://www.freebsd.org/doc/en/books/handbook/carp.html it is natively devoeloped for OpenBSD but you have it already ported to FreeBSD. I am using CARP + OpenBSD to set up redundant pair of firewals and it works perfect. In case you want one machine to shutdown, it has some problem or what ever else, second machine take a rolle of master and it works. Machines should be close to each other ( as they use crossover cable to be connected for sync interfaces ), and in case you need to set up some geographical wide redundancy , CARP will not help you. In case your nagios servers are in same server room, I think CARP can be useful Nice regards, Arlen On Thu, Aug 27, 2009 at 3:08 AM, Mark Gius wrote: > We use two identically configured servers with a shared DRBD > (http://www.drbd.org/) partition that contains the nagios state/log/config > files, Linux Heartbeat (http://www.linux-ha.org/), and a role IP address to > do redundancy.

Re: [Nagios-users] Redundant Nagios setups...
We use two identically configured servers with a shared DRBD (http://www.drbd.org/) partition that contains the nagios state/log/config files, Linux Heartbeat (http://www.linux-ha.org/), and a role IP address to do redundancy. We can literally yank the plug on one of the servers and nagios will be back up in about 10 seconds. I wouldn't say I suggest this solution (we're doing it because the nagios servers also host a number of other services that we want to failover automatically) but it does achieve automated redundancy/failover. -Gius Janet Sullivan wrote: Other than the methods described in the official docs (http://nagios.sourceforge.net/docs/3_0/redundancy.html) and Merlin (http://www.op5.org/community/projects/merlin) are there any other suggested solutions for setting up redundant Nagios servers? -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

What kind of system architecture have you implemented so far? What add-ons are you using? What other systems are you integrating with Nagios? DNX as another one that is pretty popular: it is more for high capacity than redundancy but it does provide for high availability with polling, you just have to set up redundancy at the scheduler level http://dnx.sf.net/ - Max -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
