This package contains libraries to help instrument Ktor. Currently, only server instrumentation is supported.

Quickstart

Add these dependencies to your project

Replace OPENTELEMETRY_VERSION with the latest release.

For Maven, add to your pom.xml dependencies:

<dependencies>
  <dependency>
    <groupId>io.opentelemetry.instrumentation</groupId>
    <artifactId>opentelemetry-ktor-1.0</artifactId>
    <version>OPENTELEMETRY_VERSION</version>
  </dependency>
</dependencies>

For Gradle, add to your dependencies:

Usage

Initialize instrumentation by installing the KtorServerTracing feature. You must set the OpenTelemetry to use with the feature.

OpenTelemetry openTelemetry = ...

embeddedServer(Netty, 8080) {
  install(KtorServerTracing) {
    setOpenTelemetry(openTelemetry)
  }
}
