Icinga is an open source system and network monitoring application. It is used to monitor both network infrastructure and applications to ensure they are running efficiently. In this tutorial, I will be showing you how to install Icinga on NixOS Latest.
Before installing Icinga, make sure all dependencies are installed. We will be using the Nix package manager for this installation, so it should already be installed.
To install Icinga, follow the steps below:
sudo nix-channel --update
sudo nix-env -iA nixos.icinga
After installation, we need to configure Icinga. Follow these steps to do so:
/etc/icinga2/icinga2.conf with a text editor.sudo vim /etc/icinga2/icinga2.conf
Find the line that begins with include "conf.d", and make sure it is uncommented. This line tells Icinga2 to include any services defined in files located in the /etc/icinga2/conf.d directory.
Save the file and exit.
Now, you can start Icinga with the following command:
sudo systemctl start icinga2
You can also enable Icinga to start automatically on boot with:
sudo systemctl enable icinga2
Icinga also has a web interface that allows you to view your network and system status from a web browser. To access the interface, follow these steps:
Open your browser and navigate to http://<server-IP-or-domain>/icingaweb2.
Login using the default administrator credentials. You'll be prompted to change the password upon logging in.
You should now have access to the Icinga web interface.
In this tutorial, you have learned how to install Icinga on NixOS Latest, and how to configure and start it. Additionally, you learned how to access the Icinga web interface to view network and system status from a web browser.
Icinga provides a great way to monitor and manage your system and network infrastructure. Enjoy managing your network with Icinga!
