Munin is an open source monitoring tool for system resources such as CPU, memory, disk space, and network usage. This tutorial will guide you through the process of installing Munin on OpenBSD.
Before proceeding with the installation of Munin, ensure that the OpenBSD system packages are up-to-date by running the following command:
sudo pkg_add -u
Next, install Munin by running the following command:
sudo pkg_add munin
Once Munin is installed, the configuration files can be found in /etc/munin/ directory. Before Munin can start monitoring system resources, we need to update the Munin configuration.
First, edit /etc/munin/munin.conf file:
sudo vi /etc/munin/munin.conf
Add the following two lines to the file:
dbdir /var/munin
htmldir /var/www/htdocs/munin/
Next, add the following line for each system you want to monitor, replacing <hostname> with the hostname of the system:
[<hostname>]
address <ip_address>
After configuring Munin, we need to start the daemon:
sudo /etc/rc.d/munin-node start
This will start the Munin node and allow it to begin monitoring system resources.
To access the Munin web interface, open your web browser and enter <ip_address>/munin in the address bar. Replace <ip_address> with the IP address of the OpenBSD system running Munin.
In this tutorial, we have shown you how to install and configure Munin on OpenBSD. You are now able to monitor system resources using Munin.
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!
