Changelog

All notable changes to this project will be documented in this file.

This project adheres to Semantic Versioning.

0.4.0

This release is by far the most feature rich update of the reporter. This wouldn't be possible without the amazing contributions we received! 💛

See the documentation for the new version at https://hexdocs.pm/telemetry_metrics_statsd/0.4.0.

Highlights

The reporter is now compatible with Telemetry.Metrics 0.5.0, which means that it respects the :keep and :drop options set on metrics. The :buckets option on distribution metrics is no longer required and it can be safely removed from these metric definitions (the option was redundant for the StatsD reporter since the beginning).

If you are running reporter in a high volume environment, you can now set the sampling rate of each metric via the :sampling_rate reporter option, to limit the number of metric updates sent to the StatsD daemon.

And last but not least, we have a few enhancements in how Telemetry.Metrics map to metric types in StatsD/DataDog:

  • Both formats now support exporting sum metric as a monotonically increasing counter (via report_as: :counter reporter option).
  • For DataDog, summary is now exported as a histogram, while distribution maps to DataDog distribution metric.
