Docker Deploy: Grafana

This repo contains a demo setup for the django-prometheus plugin, which exposes Django usage metrics as a Prometheus end point. See their README on how to use it.

Spin up

To build and spin up the demo environment:

docker-compose build
docker-compose up

Once the stack has booted up, you can visit:

• http://localhost:8000/polls to get to the entry point for the API of the demo app.
• http://localhost:8000/metrics to get the metrics exposed to Prometheus.
• http://localhost:3000 to go to Grafana, where you can view the "Django Prometheus" dashboard

You will see that the django-prometheus plugin will expose general statistics like:

• Backend database performance,
• HTTP response times,
• CRUD operations on models that have been extended with the ExportModelOperationsMixin class.

Example metric exposed by this plugin (for a full list see example-exposed-metrics.txt):

# HELP django_model_inserts_total Number of insert operations by model.
# TYPE django_model_inserts_total counter
django_model_inserts_total{model="question"} 0.0
django_model_inserts_total{model="choice"} 0.0

Furthermore, the default dashboard relies on prometheus/django.rules to evaluate those formulas faster when asked.
