Prometheus metrics

PlanetScale exposes a Prometheus-compatible endpoint per-branch that allows you to scrape metrics for your database.

Overview

See our Prometheus integration documentation for how to set Prometheus up to automatically discover and scrape metrics for your database branches.

If you’re using Datadog, see our Datadog tutorial for how to setup your Datadog agent to scrape metrics for your branch.

Metrics

PlanetScale emits the following metrics to be scraped.
