As anyone who has ever been responsible for a networked computer system knows, keeping
track of what's happening in such a network is of critical importance. You need to know
when things go wrong by being alerted rather than manually polling. You would like to have
automated restart of failed components. You would like a tool that presents a graphical inter-
face so you can quickly see what's happening in the environment. Nagios is such a tool. Like
many products in the open source world, there is a version that you can freely download, and
expanded versions that are licensed at a cost.
The open source core product has many useful features. It provides monitoring of servers,
switches, OS, and application through a web-based interface. More important, it provides
quick detection of outages and problems and can alert your operations staff via email or text
message. There are provisions for automatic restart.
