Does anyone here know if Nagios is something I need to install on every server I wish to monitor? Can I combine the results of multiple sites into single reports or do I just need to have multiple reports?

Also: Is there a compelling reason to use Nagios 3 when nagios2 is in the repos on the server I want to monitor?
You will need to install a plugin as such to be able get the reports into nagois, the thing that nagois can "talk" to to get what is happening e.g ping plugin within nagois can find out if a server is present as such, but the reports back to the main nagois needs to be able to get reports back to genereate it's own graphs etc
Nagois 3 have additonal functions that for the life of me cannot remember the reason for the upgrade lol

You don't need to install it all, but you may want to install something there to make the status results you want available. In nagios3, there's Nagios Remote Plugin Execution and corresponding bundle of packages for those.
Some reasons for nagios3 are listed at http://nagios.cvs.sourceforge.net/*checkout*/nagios/nagios/html/docs/whatsne... and compelling depends on how you see them.
Hope that helps,

Well, nagios is more of a service monitor than anything else, and can do external http calls etc... if you actually want to monitor system disk usage etc, then I suggest instead using munin, which has a client/server setup, and is incredibly easy to tailor afterwards... You get prettier graphs too... and you can almalgamate them if you so wish.

You only need to install Nagios on the 'monitoring system(s)', I have a couple here, one is the 'live' system and the other is one I experiment with.
To see what's going on, you just 'browse' to the monitoring system with a regular browser, log in, and then you can click your way through various different views.
On the windows systems I monitor, I install a very small package called 'NSClient++'
I can monitor CPU, memory, disk space on each partition and uptime, as well as any other specific services.
On the linux systems, I just need to install NRPE, which does a similar job but on the *nix platform.
There is some useful information to be found here:
http://nagios.sourceforge.net/docs/
http://nagios.sourceforge.net/docs/3_0/addons.html
I would use version 3 of Nagios unless it's really inconvenient. There are many improvements in this version.
Best,
Simon
