Nagios Support Forum

I am extremely interested in implementing the nagios log server in my environment. I have a few questions about load balancing.

1. Your recommendation is roundrobin DNS. What happens if one of the nodes in the roundrobin dns drop? Roundrobin DNS doesn't have a keep alive. If one of the nodes in round robin dns fail what happens to the data?
2. The other recommendation is use a loadbalancer. This is costly and I'd like to avoid it.
3. Is it possible to configure Nagios Log Server to run in 3 node ha proxy configuration? This uses round roundrobin as well but has a keepalive process. If a node isnt online it skips over to the next node.
4. If ha proxy configuration is available can you please provide your recommendations?

Thanks,

Greg

#1 was one suggestion, but best practice is really what works well in your environment.

#3 This actually may become the defacto standard, and sounds like a very good way to setup the HA.

#4 We do not have one and it will really depend on the inputs you add to your system, ports, etc. if you are using global configs or are splitting them.
