Nagios or not Nagios, that is the question

Morning Guru's

Advise please,

I need to build a monitoring system at work and have read some wonderful things about Nagios. Having a very limited budget I need to spec a pc/server for this for under GBP2000. What should I be looking at for a Nagios server, is it processor or memory hungry, what about logs, how much disk space does it use ( I know this depends on size of environment, which should be up to 50 devices max) I will be running it of fedora?. Is nagios the right solution?. I want visability of everything possible, (windoze Linux, network VOIP).

I have heard good things about big brother but believe the open source license doesn't stretch to commercial operation. are there any other options out there

Any advise as always greatly appreciated.

Nagios is one of the best open source applications available. I have not seen a better monitoring tool. The company I work for uses MANY different monitoring tools, which I think is stupid, because everything i've seen done with our 10+ tools, can be done with nagios alone.

I dont know exactly what the hardware requirements / bottlenecks would be, but I dont think it would need a great investment for only 50 devices if you configure it properly (say you only scan a system every 5 minutes, you have 10 systems per minute, very little requirements, whereas if you scan every system once per minute, you are requesting 5 times as much. You must balance performance against response time.)
