django-prometheus

Hello HN :) I'm about to launch a prototype of a product. The backend is made with Python/Django. I'd like to track some metrics: - current number of users and delta from previous week - number of $MODEL inserts per hour and per day - number of API requests - min/max/average time of requests - number of 401s, 404s, 500s, etc... In an enterprise setting, I'd set up a Prometheus exporter[0] and use the company's Grafana to build a monitoring dashboard. But here, I don't have such infrastructure. The app will be deployed to fly.io with a PostgreSQL database. I'm eager to hear/read your recommendations for: - an SDK/library/framework to export the metrics from my Django app - a SAAS product to build the dashboard visualizing those metrics Thank you in advance.

While I somehow understand Prometheus idea that pull is easier to scale than push I've had a bad luck with it. First of all Prometheus doesn't even consider monitoring of long-running jobs other than pull way (which didn't make sense for me). There is push gateway [0] but clients libraries seem to consider it only for short-lived jobs where you can send the metrics at the end [1]. It seems I couldn't "push" from long living jobs trivially Second when using it for example with django you have to be careful with how you handle multiprocessing that UWSGI/gunicorn does, see [2] - it has bitten me at leas once. Comparing to push model where I can just push metrics to [3] statsd_exporter directly and be done with it, but support for statsd is lacking both in terms of frameworks (everyone seems to be migrating to native clients...) and functiona
