Have you ever been frustrated by the fact that Prometheus exporters don’t export the metrics you want? I was. So I wondered how easy it is to create a custom Prometheus exporter in Python. In fact, it’s very easy to build a new Prometheus exporter using Prometheus python client.
Therefore, we’ll develop custom Prometheus exporter in Python and show how to debug it fast. For this purpose, we’ll raise a fully functional Jenkins monitoring stack using docker.
