Alerta is an open-source monitoring system that alerts you when something goes wrong in your application or infrastructure. In this tutorial, we will go through the steps to install Alerta on NetBSD.
Before we can start installing Alerta, we need to ensure that we have all the necessary prerequisites installed.
Ensure that your NetBSD system is up-to-date by running the following command:
sudo pkgin update
Next, install the required packages using the following command:
sudo pkgin install python38 py38-pip git
Alerta requires MongoDB as its backend datastore. Install MongoDB by running the following command:
sudo pkgin install mongodb
Next, start the MongoDB service with the following command:
sudo /usr/pkg/etc/rc.d/mongodb start
To check if the service is running correctly, run the following command:
sudo /usr/pkg/bin/mongod --version
With the prerequisites in place, we can now install Alerta. We will install it using pip.
First, clone the Alerta repository using the following command:
git clone https://github.com/alerta/alerta.git
Navigate to the Alerta directory:
cd alerta
Next, install Alerta using pip:
sudo pip install -e .
We need to configure Alerta to use our MongoDB installation.
Navigate to the configuration directory:
cd /usr/pkg/etc/alerta/
Copy the default configuration file:
sudo cp alertad.conf.example alertad.conf
Open the configuration file:
sudo vi alertad.conf
Update the MongoDB configuration section with the following information:
DATABASE_URL = 'mongodb://localhost:27017/alerta'
Save and close the configuration file.
Start Alerta with the following command:
sudo alertad
You should see a message indicating that Alerta is running.
Starting Alerta server on http://localhost:8080/api/
To test if Alerta is working correctly, open a new terminal and run the following command:
curl http://localhost:8080/healthcheck
You should receive a response that indicates that Alerta is running correctly.

Congratulations! You have successfully installed and configured Alerta on your NetBSD system. You can now start configuring Alerta to monitor your infrastructure and applications.
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!
