Shortly after reading "Cheap and Effective Network Monitoring" last year in the Linux Letter column, I immediately began to acquire skills working with the well-known open-source monitoring tool discussed in that article. Since Barry Kline's article goes into great detail on what Nagios actually is and what it can do for you, I won't elaborate beyond the fact that Nagios is a host-, service-, and network-monitoring utility maintained by Ethan Galstad.
