Provides OpenTelemetry instrumentation for gRPC.
Replace OPENTELEMETRY_VERSION with the latest release.
For Maven, add the following to your pom.xml dependencies:
<dependencies>
<dependency>
<groupId>io.opentelemetry.instrumentation</groupId>
<artifactId>opentelemetry-grpc-1.6</artifactId>
<version>OPENTELEMETRY_VERSION</version>
</dependency>
</dependencies>For Gradle, add the following to your dependencies:
implementation("io.opentelemetry.instrumentation:opentelemetry-grpc-1.6:OPENTELEMETRY_VERSION")The instrumentation library provides the implementation of ClientInterceptor and ServerInterceptor to provide OpenTelemetry-based spans and context propagation.
// For client-side, attach the interceptor to your channel builder.
void configureClientInterceptor(OpenTelemetry openTelemetry, NettyChannelBuilder nettyChannelBuilder) {
GrpcTelemetry grpcTelemetry = GrpcTelemetry.create(openTelemetry);
nettyChannelBuilder.intercept(grpcTelemetry.newClientInterceptor());
}
// For server-side, attatch the interceptor to your service.
ServerServiceDefinition configureServerInterceptor(OpenTelemetry openTelemetry, ServerServiceDefinition serviceDefinition) {
GrpcTelemetry grpcTelemetry = GrpcTelemetry.create(openTelemetry);
return ServiceInterceptors.intercept(serviceDefinition, grpcTelemetry.newServerInterceptor());
}
