Munin is a monitoring tool to survey processes and resources in your machine and presents the information in graphs through a web interface.

Use the following steps to setup Munin on your machine and view your web interfaces with Apache.

Install required packages

apt-get install munin munin-plugins-extra libwww-perl apache2-utils

Create user to access the web interface

htpasswd -c /etc/munin/.htpasswd munin

This step will prompt for password.

Enable plugins for monitoring

Choose which plugin to be enabled by creating symbolic link to it:

ln -s /usr/share/munin/plugins/cpu /etc/munin/plugins/cpu

ln -s /usr/share/munin/plugins/df /etc/munin/plugins/df

ln -s /usr/share/munin/plugins/forks /etc/munin/plugins/forks

ln -s /usr/share/munin/plugins/fw_packets /etc/munin/plugins/fw_packets

ln -s /usr/share/munin/plugins/ip_127.0.0.1 /etc/munin/plugins/ip_127.0.0.1

ln -s /usr/share/munin/plugins/load /etc/munin/plugins/load

ln -s /usr/share/munin/plugins/memory /etc/munin/plugins/memory

ln -s /usr/share/munin/plugins/processes /etc/munin/plugins/processes

ln -s /usr/share/munin/plugins/threads /etc/munin/plugins/threads

ln -s /usr/share/munin/plugins/uptime /etc/munin/plugins/uptime

ln -s /usr/share/munin/plugins/exim_mailqueue /etc/munin/plugins/exim_mailqueue

ln -s /usr/share/munin/plugins/exim_mailstats /etc/munin/plugins/exim_mailstats

ln -s /usr/share/munin/plugins/postfix_mailstats /etc/munin/plugins/postfix_mailstats

ln -s /usr/share/munin/plugins/postfix_mailqueue /etc/munin/plugins/postfix_mailqueue

ln -s /usr/share/munin/plugins/mysql_queries /etc/munin/plugins/mysql_queries

ln -s /usr/share/munin/plugins/nginx_request /etc/munin/plugins/nginx_request

ln -s /usr/share/munin/plugins/nginx_status /etc/munin/plugins/nginx_status

ln -s /usr/share/munin/plugins/apache_accesses /etc/munin/plugins/apache_accesses

ln -s /usr/share/munin/plugins/apache_processes /etc/munin/plugins/apache_processes

Edit configuration

Edit /etc/munin/munin.conf file for some basic settings.

Find and change [localhost.localdomain] to your own hostname such as

Open and edit /etc/apache2/conf.d/munin.

Comment the following lines:

Order allow,deny

Allow from localhost ::1

Options None

Then, uncomment the following lines to enable authentication:

# AuthUserFile /etc/munin/.htpasswd

# AuthName "Munin"

# AuthType Basic

# require valid-user


If your Apache is listening on port other than 80, edit /etc/munin/plugin-conf.d/munin-node

Add following lines to the end of file if your Apache is listening to port 8080:


env.ports 8080


Finally, restart your services.

/etc/init.d/munin-node restart

/etc/init.d/apache2 restart

You can now access your munin web interface at http://YOUR_SERVER_IP/munin.

The Munin graphs will be available after few minutes.
