Xymon is a system for monitoring of hosts and networks, inspired by the Big Brother system. It provides real-time monitoring, an easy web-interface, historical data, availability reports and performance graphs.

Xymon keeps all configuration data in one place: On the Xymon server. Big Brother has lots of configuration files stored on the individual servers being monitored, so to change a setting you may need to logon to several servers and change each of them individually.

With the Xymon client running and reporting data into Xymon, you should see the cpu-, disk-, memory- and procs-columns appear. The color of these status columns is determined by settings in the analysis.cfg configuration file.

The Xymon client package is installed automatically only on the Xymon server - on other systems, you must build the client package by running Xymon's configure-script with the "--client" option and build the client package on the hosts you want to monitor.

Since you probably don't have the Xymon webpages in view all of the time, Xymon can generate alerts to draw your attention to problems. Alerts can go out as e-mail, or Xymon can run a script that takes care of activating a pager, sending an SMS, or however you prefer to get alerted.
