How to Install Prometheus on NetBSD

Prometheus is a free, open-source monitoring and alerting toolkit. It helps you collect and analyze metrics from your systems, applications, and services. In this tutorial, we will show you how to install Prometheus on NetBSD.

Prerequisites

Before you begin, make sure your NetBSD server meets the following requirements:

  • You have root access to the NetBSD server.
  • You have a user account for running Prometheus.
  • NetBSD is up-to-date.

Step 1: Install Go

To install Prometheus, you need Go installed on your NetBSD server. To install Go, follow these steps:

  1. Open a terminal window on your NetBSD server.
  2. Type the following command to download the Go tarball from the official website:
$ ftp https://golang.org/dl/go1.15.8.linux-amd64.tar.gz
  1. Once downloaded, extract the tarball using the following command:
$ tar -C /usr/local -xzf go1.15.8.linux-amd64.tar.gz
  1. Set the environment variables for Go by adding the following lines to /root/.profile:
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
  1. Save and close the file.

Step 2: Install Prometheus

To install Prometheus, follow these steps:

  1. Open a terminal window on your NetBSD server.
  2. Type the following command to download the latest Prometheus release from the official website:
$ ftp https://github.com/prometheus/prometheus/releases/download/v2.26.0/prometheus-2.26.0.linux-amd64.tar.gz
  1. Once downloaded, extract the tarball using the following command:
$ tar -xzf prometheus-2.26.0.linux-amd64.tar.gz
  1. Move the prometheus-2.26.0.linux-amd64 directory to /usr/local/:
$ mv prometheus-2.26.0.linux-amd64 /usr/local/prometheus
  1. Create a user for running Prometheus:
$ useradd -M -s /sbin/nologin prometheus
  1. Change the ownership of the /usr/local/prometheus directory:
$ chown -R prometheus: /usr/local/prometheus

Step 3: Configure and Run Prometheus

To configure Prometheus, follow these steps:

  1. Open the /usr/local/prometheus/prometheus.yml file:
$ vi /usr/local/prometheus/prometheus.yml
  1. Add the following targets to the scrape_configs section:
- job_name: 'netbsd'
  scrape_interval: 15s
  static_configs:
    - targets: ['localhost:9090', 'localhost:9100']

This will scrape metrics from the NetBSD server itself and the node_exporter.

  1. Save and close the file.

To run Prometheus, follow these steps:

  1. Open a terminal window on your NetBSD server.
  2. Change to the prometheus user:
$ su - prometheus
  1. Start Prometheus:
$ /usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml
  1. Verify that Prometheus is running by opening a web browser and navigating to http://<your-server's-IP-address>:9090.

Conclusion

In this tutorial, we showed you how to install Prometheus on NetBSD. With Prometheus running, you can now start monitoring your systems, applications, and services in real-time.
