How to Install Alerta on Arch Linux

Alerta is an open-source alert management system that integrates with monitoring tools such as Nagios, Zabbix, and Prometheus, to name a few. This tutorial will guide you through installing Alerta on Arch Linux.

Prerequisites

Before you start, make sure you have the following prerequisites:

  • A running instance of Arch Linux with root or sudo privileges
  • Packages git, python-pip, and python-virtualenv installed

Step 1: Install Required Dependencies

We will start by installing the dependencies required by Alerta.

Open the terminal and use the following command to update the package list:

Step 3: Create a Virtual Environment

Alerta recommends using a virtual environment to manage the Python dependencies. Create a virtual environment with the following command:

virtualenv -p python3 venv

Activate the virtual environment with the following command:

source venv/bin/activate

Step 4: Install Python Dependencies

After activating the virtual environment, install the required Python dependencies with the following command:

pip install -r requirements.txt

Step 5: Configure Alerta

Alerta comes with a sample configuration file that you can use as a starting point. Make a copy of the sample configuration file with the following command:

cp alerta.conf.sample alerta.conf

Edit the alerta.conf file to match your requirements.

Step 6: Start Alerta

Start Alerta with the following command:

alertad run

By default, Alerta listens on port 8080. You can verify that Alerta is running by opening a web browser to http://localhost:8080.
