How to Deploy Munin to Monitor Servers

Munin is a popular system & network monitoring tool. It relies on the RRDTool to generate illustrations of resource usage.

Furthermore, we can monitor multiple nodes via a single installation as well.

In order to configure Munin, we have to configure the server and the client.

How to Install & Configure Munin on the Server

We can install the Munin server on Ubuntu/Debian-based machines with this command:

# apt-get install munin apache2

If we plan to install it on a Redhat/Centos-based machine, we have to enable EPEL repo since these machines do hot have Munin in their repos by default.

# yum install munin httpd

Now, let’s take a look at how to configure the Munin server:

1. First, we have to add hosts entry in /etc/munin/munin.conf. We have to go to the end of the file and the client to monitor.
2. Then save the file and exit.
3. After that, we have to edit or create munin.conf file in /etc/apache2/conf.d folder and add the following content to it:

   
4. Then, save the file and exit.
5. Now, it is time to create a username and password in order to view the munin graphs:

   # htpasswd -c /etc/munin/munin-htpasswd munin

   Remember to replace “apache2” with “httpd” in the config file path for Redhat/Centos machines.

6. Next, we have to restart the Apache server.

How to Install & Configure Munin on the Client

1. First, we have to Install the Munin client in Linux:

   # apt-get install munin-node
# yum install munin-node

   Our experts would like to point out that we have to install munin-node on the server if we plan on monitoring the Munin server as well.
2. Now, it is time to edit the munin-node.conf file to include the address to bind to as well as the port information.
3. Then, restart munin-node on the client.

Now, it is time to test the connection and ensure that we can connect to the client from the server on the 4949 port. Furthermore, we can access the Munin web interface at this link.
