This is a template repository for running Prometheus on Render. To show how to configure Prometheus on Render, this template includes a sample Flask applcation which exports HTTP request metrics to Prometheus.
Click the button below to deploy Prometheus and sample Flask to your Render account:
Once the Blueprint is succesfully deployed, two services will be created.
In the prometheus service dashboard, you can click the onrender.com URL to open Prometheus web UI. You can use this interface to query Prometheus metrics.
For production service, we recommand to add authentication to limit the access.
Now you can try to call flask service with the onrender.com URL from the flask service dashboard.
curl https://flask-<REPLACE ME>.onrender.com/one
Go back to Prometheus web UI and query the flask service's total number of HTTP requests:
sum(flask_http_request_total)
The number should be increased.
If your service already exports metrics to Prometheus, you can use another template render-prometheus-only.yaml which doesn't create sample flask service. Please fork this repo and replace existing render.yaml.
cp render-prometheus-only.yaml render.yaml
When you deploy this Blueprint, it will ask for your service name and port.
You can find them from the Internal Address in your service dashboard. In this example, SCRAPE_SERVICE_NAME is flask-4dx6 and the SCRAPE_SERVICE_PORT is 5000.
This template only configure Prometheus to scrape one service. For multiple service, please directly update
prometheus.yml.
