otel4s

Telemetry meets higher-kinded types

otel4s is an OpenTelemetry implementation for Scala. The design goal is to fully and faithfully implement the OpenTelemetry Specification atop Cats Effect.

Features

• otel4s provides APIs and implementations for metrics and tracing.

• Core modules for JVM, Scala.js, and Scala Native offer an API with no-op implementations. These are appropriate for library instrumentation.

• opentelemetry-java backend provided for the JVM. This provides working telemetry for applications.

Status

The API is still highly experimental, but we are actively instrumenting various libraries and applications to check for fit. Don't put it in a binary-stable library yet, but we invite you to try it out and let us know what you think.

Getting started

• Start tracing your application with Jaeger and Docker
• Implement tracing and metrics with Honeycomb
