OpenTelemetry API and SDK for Kotlin MPP

[JochenGuckSnk]

Hello Team,

Kotlin multi-platform (https://kotlinlang.org/docs/mpp-intro.html) is becoming more and more traction nowadays. It enables to program full stack applications. I am wondering if there are any plans to provide a API and SDK written in Kotlin?

I have already a port of the Tracing and Metrics SDK from OpenTelemetry-Jave in to Kotlin.

• The Tracing SDK is working on JVM; JS and Native target.
• The Metrics SDK works only on JVM and Js.
• Exporters are missing right now.

I wonder if there is any interest in using this as a starting point for an official OpenTelemetry-Kotlin SDK.

I just want to shear a small update. Metrics SDK is now also working on native. If u are interested in the code you can find it on Github https://github.com/dcxp/opentelemetry-kotlin. There are also maven packages.

Can you register those in the registry? https://opentelemetry.io/registry/?s=kotlin&component=&language=

I created a pull request open-telemetry/opentelemetry.io#1145 for adding the project to the repository. Just have to go through the CLA process from my side.
