2/03/2015 – Installing Munin on cPanel Servers

Posted by Jamison on 03 02 2015.

When your website monitoring system is not working to par, you might want to switch to Munin—one of the best monitoring tools there is to serve your website. If you haven’t heard of this software before or if you are planning to install one to your server, this article will give you a better knowledge about this tool—from the 101s to the installation. So let’s start.

 

What is Munin?

 

Etymologically speaking, Munin means memory—and this meaning has a lot to do with Munin’s function on your machine.

 

This is a monitoring system that gives you updated reports with regards to your website’s usage, applications, plug-ins, performance, trends, and other aspects of your site. In other words, Munin monitors everything that is there in your website. It gives you reports through organized graphs daily, weekly, monthly, and yearly. With this, you will always know what is going on with your site, detect an issue, and be able to fix it before it gets worse. It makes it very easy for you to see what’s happening on your website and even on your computer.

 

What OS and architectures are supported by Munin?

 

Fortunately, this tool supports almost all operating systems, and the developers are still accepting contributions to create plugins for new OSes. Same goes with architectures. Munin should fit to most architectures provided that you install perl modules to your cPanel.

 

How to install Munin on cPanel

 

Installation is quite straightforward. On a side note, you should have Perl5 or perl modules on your server before installing this tool to your cPanel. And make sure that it is the latest version of perl modules. GNU Make is required as well.

 

  1. Login to your cPanel account and look for Manage Plugins.
  2. Inside the plugins page, look for a command that says Install and Keep Updated. Click it and then save.
  3. Installation will take at least five to ten minutes depending on the plugins enabled together with Munin.
  4. Once it’s completed, go to Munin Service Monitor and check if the plugin is already installed.
  5. Now, if you see a blank page, you will have to update your cPanel’s CURRENT/STABLE release through /scripts/upcp.
  6. Using this link, you will find different services and plugins used by cPanel. Identify the tools that you require and get the latest or at least a higher plan suited for your hosting needs.
  7. After installation, restart the Munin node using “service munin-node restart”
  8. Wait for the graph to appear on your WHM plugin and that’s it!

 

These steps may vary according to the version of cPanel, Munin, OS, and other plugins you are using. But for most versions, this guideline should do the trick. If not, go to cPanel and Munin’s websites and check out their updates. Don’t worry; with the right guide to show you how to install any software that you needed, you will not mess up. But keep in mind to only ask help from the expert.
