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.
Before beginning, make sure you have the following:
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
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
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.
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=['admin@example.com']
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.
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.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
