How to Install Riemann on OpenBSD

Riemann is an event stream processor that can be used to monitor and analyze system metrics in real time. In this tutorial, we will show you how to install Riemann on OpenBSD.

Prerequisites

  1. OpenBSD installed and configured on your system.
  2. Basic knowledge of the OpenBSD command-line interface.

Installation

Step 1: Add the Riemann Package Repository

Before we can install Riemann, we need to add the package repository where it can be found.

  1. Open the /etc/installurl file in your favorite editor.
$ sudo vi /etc/installurl
  1. Add the following line to the file:
https://cdn.openbsd.org/pub/OpenBSD/$(uname -r)/packages/$(uname -p)/

Step 2: Install the Riemann Package

Now that the Riemann repository has been added, we can proceed to install the package.

  1. Open a terminal window on your OpenBSD system.

  2. Use the following command to install the Riemann package:

$ sudo pkg_add riemann

This will download and install the Riemann package along with its dependencies.

Step 3: Configure Riemann

After installation, we need to configure Riemann to start automatically at boot time.

  1. Open the /etc/rc.conf file in your favorite editor.
$ sudo vi /etc/rc.conf
  1. Add the following line to the file:
riemann_flags="-f /etc/riemann.config"

This line tells Riemann to read its configuration from /etc/riemann.config.

  1. Save and exit the file.

Step 4: Start the Riemann Service

In order to use Riemann, we need to start the service.

  1. Use the following command to start the Riemann service:
$ sudo rcctl start riemann
  1. Verify that the Riemann service is running by issuing the following command:
$ sudo rcctl check riemann

If the service is running, you should see the following output:

riemann(ok)

Congratulations, you have successfully installed and configured Riemann on OpenBSD!
