AEleen Frisch at OnLamp covers her #2 open source sysadmin program: Nagios. (It used to be called Netsaint for those of you, who like me, were confused). Here’s a little overview, but read the whole article if you are interested:
The second place in my top five tools list goes to Nagios, written by Ethan Galstad. Nagios is a feature-rich network monitoring package. Its displays provide current information about system or resource status across an entire network. In addition, it can also be configured to send alerts and perform other actions when problems are detected. This week, we’ll look at the sort of monitoring that Nagios provides and also briefly discuss configuring the package.
I looked into installing Netsaint a while ago, and decided that it was a bit of overkill for what I was doing. Now that I have several *nix machines running various stuffs, I might give Nagios a try. My prediction for her #1 open source sysadmin program is Webmin. If it’s not, something is wrong.
