Feed Apache Samza metrics into Prometheus

This blog post from Ditial Ocean explains how to setup Prometheus. The easiest is to run the docker image. Specify the PORT, BROKERS and TOPIC env variables when running the image. To run outside docker, install with:

sudo pip3 install .

And then run samza-prometheus-exporter

To install the package in editable development mode:

sudo pip3 install -e .

This project is heavily based on prometheus-es-exporter
