Some of you might know Nagios, some of you might not. Nagios is a network and server monitoring system. It’s open source and widely used (at least that’s my impression). I now use Nagios to monitor all of my network, and my server it self. More here
It’s my impression that most people install Nagios by downloading af tarball and do: `./configure && make && make install`. However, I might be wrong. Unless it the only option, I think that it is a bad way to install software.
