Munin is a networked resource monitoring tool that can help analyze resource  trends and usage. It can monitor a wide variety of servers and equipment e.g.  servers, vpss, networks, applications etc.

Munin provides very useful graphs with resource usage listed for different time periods like , daily , weekly and monthly graphs.

Installation of Munin as plugin on cPanel servers or vpss is very easy and straight forward.

Go to below link in your WHM interface :

WHM >> cPanel >> Manage Plugins

You will find the Munin in the plugins section. Just check the check box in that section which says ‘ Install and keep updated ‘ and press save from the bottom of the page.

You will see the installation steps in the gui and it will complete in 5 to 10 minutes.

Once the installation is complete, you will find the plugin available at below path :

WHM >> Plugins >> Munin Service Monitor

In some cases you may encounter a blank page when you click on this link , in that case upgrade cpanel to latest CURRENT/STABLE release depending on your requirements using /scripts/upcp.

At this link you will find graphs for following services and equipment :

Apache, Disk, Exim, Mysql, Network, Other, Processes, System

Be default both daily and weekly graphs for each the above are available. Which give you very good idea on your resource consumption and to identify any bottle necks.

Its also a very good tool to identify if and when you need to upgrade to a higher plan for your hosting requirements.

For a non cPanel server you can do the installation by downloading the source directly and then install it. Or you can also do simple yum based installation.

After the installation you will need to configure the related files at /etc/munin path.  I will not be covering the manual installation details in this article , however the steps are not difficult and you can find plenty of articles covering them on internet.
