How to install Monitorix in Ubuntu

To install Monitorix in Ubuntu

Monitorix is a free, lightweight, open source monitoring tool designed to monitor many services and system resources as possible on servers and desktops. It mainly consists of two programs: a collector, called Monitorix, which is a Perl daemon that is started automatically as a system service, and a CGI script called monitorix.cgi. Since Monitorix 3.8.1 version includes its own HTTP server as built-in, so you aren' t forced to install a third-party web server to use it.
