+
+[![CI](https://github.com/beam-telemetry/telemetry_metrics/actions/workflows/ci.yml/badge.svg)](https://github.com/beam-telemetry/telemetry_metrics/actions/workflows/ci.yml)

+
+Telemetry.Metrics provides a common interface for defining metrics based on
+[`:telemetry`](https://github.com/beam-telemetry/telemetry) events. These metrics
+can then be published to different backends using our Reporters API. See the
+[official documentation](https://hexdocs.pm/telemetry_metrics) for more information.
+
+## Reporters
+
+The following reporters are available:
+
+  * [peep](https://github.com/rkallos/peep) - reporter for Prometheus and StatsD
+
+  * [telemetry_metrics_statsd](https://github.com/beam-telemetry/telemetry_metrics_statsd) - reporter for StatsD
+
+  * [telemetry_metrics_prometheus](https://github.com/beam-telemetry/telemetry_metrics_prometheus) - reporter for Prometheus
+
+Other libraries are also available to report telemetry events, albeit without using Telemetry.Metrics, such as [OpenTelemetry bindings for telemetry](https://github.com/open-telemetry/opentelemetry-erlang-contrib/tree/main/utilities/opentelemetry_telemetry).
