Implement a Call.Factory for okhttp 3.x+ library instrumentation (#3812)
* Add a README for the okhttp library instrumentation.

* Create new instrumentation for okhttp3 4.x+

This exposes a `Call.Factory` which will properly handle internal context propagation when used with async callbacks.

* update the "4.x" instrumentation to support 3.x

* Get rid of the 4.x instrumentation, and just update the 3.x instrumentation to work

* updates from PR review

* replace old reflection with method handle usage

* Apply suggestions from code review

Manual Instrumentation for OkHttp3 version 3.0.0+

Provides OpenTelemetry instrumentation for okhttp3.

Quickstart

Add these dependencies to your project:

Replace OPENTELEMETRY_VERSION with the latest stable release. Minimum version: 1.5.0

For Maven, add to your pom.xml dependencies:


<dependencies>
  <dependency>
    <groupId>io.opentelemetry.instrumentation</groupId>
    <artifactId>opentelemetry-okhttp-3.0</artifactId>
    <version>OPENTELEMETRY_VERSION</version>
  </dependency>
</dependencies>

For Gradle, add to your dependencies:

implementation("io.opentelemetry.instrumentation:opentelemetry-okhttp-3.0:OPENTELEMETRY_VERSION")

Usage

The instrumentation library provides an OkHttp Call.Factory implementation that wraps an instance of the OkHttpClient to provide OpenTelemetry-based spans and context propagation.

import io.opentelemetry.api.OpenTelemetry;
import io.opentelemetry.instrumentation.okhttp.v3_0.OkHttpTracing;
import okhttp3.Call;
import okhttp3.OkHttpClient;

import java.util.concurrent.ExecutorService;

public class OkHttpConfiguration {

  //Use this Call.Factory implementation for making standard http client calls.
  public Call.Factory createTracedClient(OpenTelemetry openTelemetry) {
    return OkHttpTracing.newBuilder(openTelemetry).build().newCallFactory(createClient());
  }

  //your configuration of the OkHttpClient goes here:
  private OkHttpClient createClient() {
    return new OkHttpClient.Builder().build();
  }
}
