Server Monitoring Software

[Billy41684]

I can second the Nagios suggestion. My old job we used Nagios to monitor about 2000 servers with about 20,000 services combined. I've used it before on my own network, but it was a little overkill (like hackertarget mentioned) for my piddly 4 servers, lol, so I removed it from the network.

I only have 1 dedicated server currently, so I use www.pingdom.com for server monitoring. When I signed up they were having something like a 75% off sale, which worked out quite well for me.

I haven't looked into Pingdom prices for when/if I exceed their basic package, but if at some point it is no longer cost effective to use them for monitoring I will be checking out Nagios if that time comes.

I've never heard of Cacti until now... It also looks like a good product, thanks for posting that link.
