# Prometheus Formatter

Browser extension which makes plain Prometheus/OpenMetrics output easier to read.

This extension is a simple syntax highlighter for Prometheus and OpenMetrics formats. For the highlighting to work, metric endpoints **must** use either HTTP Content-Type [`application/openmetrics-text`](https://github.com/OpenObservability/OpenMetrics/blob/main/specification/OpenMetrics.md#overall-structure) or [`text/plain`](https://prometheus.io/docs/instrumenting/exposition_formats/#text-based-format). 

For plain-text metrics, parsing is limited by default on URL paths matching '/metrics', '/federate', '/probe', '/prometheus' and '/actuator/prometheus'. By clicking on the extension's icon, you can define your own paths (Regular Expressions are supported), which will override the default list.

For highlighting in the terminal: [promcolor](https://github.com/fhemberger/promcolor).
