Promgen is a configuration file generator for Prometheus. Promgen is a web application written with Django and can help you do the following jobs.

• Create and manage Prometheus configuration files
• Configure alert rules and notification options

See the Promgen introduction slides for more details.

Below are the steps to get started with Promgen.

Initialize Promgen using Docker.

# Initialize required settings with Docker container
# This will prompt you for connection settings for your database and Redis broker
# using the standard DSN syntax.
# Database example: mysql://password:username@hostname/databasename
# Broker example: redis://localhost:6379/0
docker run --rm --network host -v ~/.config/promgen:/etc/promgen/ promgen:latest bootstrap
# Apply database updates
docker run --rm --network host -v ~/.config/promgen:/etc/promgen/ promgen:latest migrate

You can then use your favorite configuration management system to deploy to each worker.

Note: Promgen aims to use the XDG specs and follows suggestions made by the 12-Factor App.

Configure Prometheus to load the target file from Prometheus and configure AlertManager to send notifications back to Promgen.

See the example settings files for proper configuration of Prometheus and AlertManager.

• Example settings file
• Example Prometheus file
• Example AlertManager file

Run Promgen using the following command.

# Run Promgen web worker. This is typically balanced behind an NGINX instance
docker run --rm --network host -p 8000:8000 -v ~/.config/promgen:/etc/promgen/ promgen:latest web

# Run Promgen celery worker. Make sure to run it on the same machine as your Prometheus server to manage the config settings
docker run --rm --network host -v ~/.config/promgen:/etc/promgen/ -v /etc/prometheus:/etc/prometheus promgen:latest worker
