Guide to Custom Metrics Backend

Goose natively supports StatsD Metrics Backend. Users might be using a different backend like Prometheus, metrics.clojure, etc. We've provided an option to integrate a custom metric backend.

As a start, refer to the implementation of StatsD.

Go through these steps to implement a Metric Backend plugin:

• Implement all functions of Metrics Protocol
• enabled? returns Truthy if metrics are enabled, Falsy otherwise
• gauge, increment & timing functions correspond to standard data types of metrics
  • They take a key, value in the context of the data type & a map of tags
  • Publish metrics to your backend or store it in-memory for scraping by metrics server
