Monitorix is a computer network monitoring tool that periodically collects system data and uses the web interface to show the information as graphs. Monitorix allows monitoring of overall system performance, and can help detect bottlenecks, failures, unusually long response times and other anomalies.
One part of the tool is a collector, called monitorix. This Perl daemon is started automatically like any other system service. The second program of Monitorix is a CGI script (monitorix.cgi). Since version 3.0 Monitorix has its own HTTP server included, what makes installing an own web server unnecessary.[1]
