Looking to setup a nice at home monitoring setup to check my multiple servers availablility and possible abuse throughout the day while I'm in the office. Considering a new cheap system loaded with redhat and nagios.org (Old Netsaint). I want to be able to see when customers are possibly abusing the machines and naturally to wake me up via page if a server goes down. Any thoughts on this setup or maybe someone else has a better setup they can share?

Thank you very much

I did a quick search at hotscripts.com and come up with a bunch of useful looking programs: http://www.hotscripts.com/cgi-bin/search.cgi?bool=AND&query=monitoring&catid=all

sorry that I don't have any specific setup to recommend.

Nagios works great.. and with a little work you can setup a distributed monitoring system so that if one monitoring machine goes down a backup can pick up. Good for when you home connection dies..

Thanks a lot for the great info on Nagios, it looks killer!

NAGIOS BABY!

Nagios is great for a nice GUI based monitor, but NEFU is far more efficient, accurate, faster, and predictable. Once you get a few hundred machines on Nagios you can get the occasional stray reports, etc. and it's a bit of a CPU hog in general. Aside from that, we use it, and it is indeed great, but for a backend, you might prefer NEFU simply due to the small size, speed, and simplicity.

Theplanet/Servermatrix use Nagios for there monitoring ...
I guess you are looking at around 10,000 servers on there setup....

Must do its job well if they are still using it.

Nagios works well for me.
