Munin is an open source monitoring tool that is used to monitor the performance of your host machine or servers. It collects various data and creates graphs that can be easily viewed in a web interface. In this tutorial, we will explain how to install Munin on Linux Mint.
Before we begin, make sure your system is up-to-date with the latest security patches and software updates.
sudo apt-get update
sudo apt-get upgrade
Munin is available in the official apt package repository of Linux Mint. So, to install it, run the following command:
sudo apt-get install munin
This command will install the Munin package and its dependencies.
After the installation, the next step is to configure Munin.
Open the Munin configuration file using your favorite text editor:
sudo nano /etc/munin/munin.conf
Add your server name to the section “[munin]” as shown below:
# Example configuration file for Munin, generated by 'make build'
# The next three variables specifies where the location of the RRD
# databases, the HTML output, and the logs, respectively. They all
# must be writable by the user running munin-cron.
dbdir /var/lib/munin
htmldir /var/cache/munin/www
logdir /var/log/munin
# A more unique name for your server, that doesn't look like a hostname
# is good.
#
# If you don't specify this, many parts of munin report “localhost.localdomain”
#
# This is a very useful setting if you have more than one host monitored
# and you want to name the HTML file after the host name.
#
[munin]
address 127.0.0.1
use_node_name yes
If you want to monitor other servers, add their IP addresses to the configuration file.
Save the file and exit.
To verify if Munin is working, run the following command:
sudo munin-node-configure --shell | sudo bash -x
This command will check the Munin configuration and install the necessary plugins.
Restart Munin for the changes to take effect:
sudo service munin-node restart
Now open your browser and go to http://localhost/munin to view the Munin graphs.
If you see the Munin graphs, then it means that Munin is successfully installed on Linux Mint Operating System.
Congratulations! You have successfully installed and configured Munin monitoring tool on Linux Mint.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
