Monitorix is a free, open source, lightweight system monitoring tool designed to monitor as many services and system resources as possible. It has been created to be used under production Linux/UNIX servers.
It consists mainly of two programs: a collector, called monitorix, which is a Perl daemon that is started automatically like any other system service, and a CGI script called monitorix.cgi. Since 3.0 version Monitorix includes its own HTTP server built in, so you don’t need to install any web server to use it.
Every time ‘monitorix’ is started it reads the configuration file from the path specified in the command line (using the -c option), and once checked, it creates the ‘index.html’ file that will act as the Monitorix main page.

Install the required packages.
# yum install rrdtool rrdtool-perl perl-libwww-perl perl-MailTools perl-MIME-Lite perl-CGI perl-DBI perl-XML-Simple perl-Config-General perl-HTTP-Server-Simple
Users of newer Fedora versions are able to install Monitorix using directly the official repositories. Therefore a simple command like the following should suffice:
# yum install monitorix
or Download CentOS RPM packages and install the Monitorix.
wget http://www.monitorix.org/monitorix-3.4.0-1.noarch.rpm
rpm -ivh monitorix-3.4.0-1.noarch.rpm
or you can install through the source file
http://www.monitorix.org/monitorix-3.4.0.tar.gz
Once succesfully installed, please take a look into the configuration file /etc/monitorix.conf to set the options according your system and enable or disable graphs.
Finally start Monitorix with:
# service monitorix start
Monitorix will start gathering the system information based on the configuration set in monitorix.conf file, and after some minutes you should be able to see the results from your favorite browser pointing it at:
