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?
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++' http://nsclient.org/nscp/ 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
