Riemann is an open-source real-time event stream processing system that is used for monitoring and alerting purposes. NixOS is a Linux distribution that is based on the Nix package manager, which provides a declarative system configuration approach.
In this tutorial, we will show you how to install Riemann on the latest version of NixOS.
Before we get started, make sure you have:
First, update your system by running the following command:
sudo nix-channel --update
sudo nixos-rebuild switch
To install Riemann on NixOS, add the following lines to your /etc/nixos/configuration.nix file:
services.riemann.enable = true;
services.riemann.package = pkgs.riemann;
Save the file and run the following command to apply the configuration changes:
sudo nixos-rebuild switch
This will download and install the Riemann package along with its dependencies.
To verify if Riemann is installed and running, use the following command:
systemctl status riemann
You should see the output that Riemann is running and active. If not, try starting the service with the following command:
sudo systemctl start riemann
To test Riemann, you can use the following command to monitor a sample event stream:
echo '{:host "localhost" :service "test" :state "ok" :metric 1}' | nc localhost 5555
This will send a sample event to Riemann, which you can see in the Riemann log file located at /var/log/riemann/riemann.log.
You have successfully installed Riemann on NixOS latest. Congratulations!
