otel-auto-scala-poc

A proof of concept project that proves the assumption that Opentelemetry metrics can be sent to an otel collector without any of the following:

• having SDK dependencies on the classpath
• having exporter-otlp or exporter-otlp-metrics dependencies
• manually instrumenting MeterProvider, Meter etc.

Runbook

Assumptions & prerequisites

• This code is not designed to be remotely deployed and run on a server. Therefore Scala's sbt (simple build tool) is to be used for running the code.
• You will need to download Opentelemetry javaagent version 1.12.0 from here
  • In the run configuration we renamed the jar to opentelemetry-javaagent-all-v1.12.0.jar adjust your configuration if you choose a different convention.
  • Place it into the resources directory.
• We use IntelliJ's sbt runner. Please reproduce the configuration locally or adjust your run environment accordingly:

Run

Run the sbt task using IntelliJ (the green trianle button).
