Description from extension meta

Makes plain Prometheus/OpenMetrics endpoints easier to read.

Image from store Prometheus Formatter
Description from store This extension is a simple syntax highlighter for Prometheus and OpenMetrics formats. Metric endpoints must use either HTTP Content-Type `application/openmetrics-text` or `text/plain`, according to spec. 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. Source code is available on GitHub under MIT license.
