How to Install Alerta on Manjaro

Alerta is an open-source monitoring tool designed to allow you to get alerted when incidents happen in your applications or infrastructure. It can be used to create alerts, notifications, and escalations based on signals coming from monitoring systems like Nagios, Zabbix, and Sensu. In this tutorial, we will outline how to install Alerta on Manjaro.

Prerequisites

Before beginning, make sure you have the following:

• A Manjaro Linux machine
• Root access on your Manjaro Linux machine
• A basic understanding of the Manjaro terminal

Step 1: Install Dependencies

First, we need to install Python, pip, and Node.js. To do this, open the Manjaro terminal and enter the following command:

sudo pacman -S python python-pip nodejs npm

Step 2: Install MongoDB

Alerta requires a database to store its data. We will use MongoDB since it is the recommended database. To install MongoDB, run the following command:

sudo pacman -S mongodb

Next, we need to enable and start the MongoDB service:

sudo systemctl enable mongodb
sudo systemctl start mongodb

Step 3: Install the Alerta Package

The easiest way to install Alerta is to use pip. To do this, run the following command:

sudo pip install alerta-server alerta

This will install Alerta and all of its dependencies.

Step 4: Configure Alerta

We need to create a configuration file for Alerta. Open a new terminal window and run the following command:

sudo nano /etc/alertad.conf

Copy and paste the following configuration file into the editor:

[DEFAULT]
DEBUG=True

PLUGINS=['reject','aws']
AUTH_REQUIRED=False
ADMIN_USERS=['[email protected]']
CORS_ORIGINS=[]

DATABASE_URL=mongodb://localhost/alerta

SECRET_KEY="your_secret_key_here"

ALLOWED_ENVIRONMENTS=["Production","Development"]
DEFAULT_ENVIRONMENT="Development"

[web]
BASE_URL=https://alerta.example.com
#SERVER_NAME=alerta.example.com

[reject]
EVENT_TYPE=[ "Heartbeat", "unknown" ]
ALERT_TAGS=[ "unknown-environment"]

[aws]
ACCESS_KEY_ID='AWS_ACCESS_KEY_ID'
SECRET_ACCESS_KEY='AWS_SECRET_ACCESS_KEY'
SNS_TOPIC_REGION='AWS_REGION'
SNS_TOPIC_ARN='AWS_SNS_TOPIC_ARN'

Note: Be sure to replace "your_secret_key_here" with a secret key of your choice.

Save and exit the configuration file by pressing CTRL+X, then Y, and ENTER.

Step 5: Start the Alerta Service

Finally, we need to start the Alerta service. Run the following command:

sudo systemctl start alerta

You can now access Alerta by going to http://<your_server_IP>:8080 in your web browser.

Congratulations! You have successfully installed Alerta on Manjaro.
