Overview

This is the Prometheus Go client library. It provides several distinct functions, and there is separate documentation for each respective component. You will want to select the appropriate topic below to continue your journey:

  1. See the exposition library if you want to export metrics to a Prometheus server or pushgateway

  2. See the consumption library if you want to process metrics exported by a Prometheus client. (The Prometheus server is using that library.)
