    <groupId>io.opentelemetry.instrumentation</groupId>
    <artifactId>opentelemetry-ktor-3.0</artifactId>

Usage

Initializing server instrumentation

Initialize instrumentation by installing the KtorServerTelemetry feature. Make sure that no other logging plugin is installed before this. You must set the OpenTelemetry to use with the feature.

val openTelemetry: OpenTelemetry = ...

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

Initializing client instrumentation

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

val openTelemetry: OpenTelemetry = ...

val client = HttpClient {
  install(KtorClientTelemetry) {
    setOpenTelemetry(openTelemetry)
  }
}
