Hi, I am looking into implementing a redundant monitoring setup using Nagios. I have read the Nagios documentation, but the solution(s) presented there have a couple of drawbacks, imho: they require extra configuration, and/or they do not keep all history information consistent accross both systems.
Just this week, I came accross a Nagios installation where two copies of the main nagios process were running from the same configuration. This setup had been running like this for almost two months, and the only apparent problem was that two notifications were sent out for every problem/recovery. So this got me thinking if this setup would work: - A highly available NFS backend - Two Nagios servers with /var/run/nagios mounted on the NFS backend. - configuration information (/etc/nagios) is replicated accross both nodes - only one nagios process running, and monitoring of both nagios systems. If one fails (either a complete host failure or a failure of the nagios process), the other node starts up nagios and continues from the data in /var/run/nagios Is this scenario too good to be true ? Are there any quirks I am overlooking ? Or is anyone running this setup ? I'd be really happy if someone could tell me this would actually work. Alternatively I'm interested to know what kind of redundant monitoring setup people are running that require minimal configuration and keep all logging information centralized. Thanks in advance!
