# Prometheus: writing a custom metrics exporter

## When to use

Use this skill for writing a custom metrics exporter in Prometheus. This skill
specifically handles writing a custom metrics exporter and nothing else in the
Prometheus family.

## Procedure

Build a custom exporter exposing `/metrics` with correct types (counter/gauge/histogram) and labels.

## Notes

This is the Prometheus skill dedicated to writing a custom metrics exporter.
Sibling skills cover other Prometheus capabilities; this one
is the right choice only when the task is about writing a custom metrics exporter.
