Cowboy is probably the most popular HTTP server for the Erlang and Elixir ecosystem. Here’s how to get metrics from it.

In the previous post of the series, I added basic metrics reporting to Cowboy, and simply wrote them to the logger. In this post, I’m going to do the same for the HTTP client, Hackney,.

In the previous posts, we gathered metrics from Cowboy and Hackney. I’d like to publish the metrics to Prometheus.
