Prometheus Native Histogram

This repository serve as a demo for the new native histrogam from Prometheus.

For the reminder, native histogram is a feature that will allow creating more precise and performant histogram inside Prometheus than the current one (you know the series with the le label)

This repository will also demonstrate visualizing such histogram inside Grafana

How to use this

You need docker and docker compose for this demonstration

Just :

docker compose up -d

Then you can visit prometheus here http://localhost:3000 and run promql query against the new histogram :

rpc_durations_native_histogram_seconds
# or
rate(rpc_durations_native_histogram_seconds[30s])

Or visit this grafana dashboard to get a sneak peek at the heatmap for this new histogram compared to the old one http://localhost:3000/d/native-histogram
