# Library Instrumentation for OkHttp version 3.0 and higher
|
|
|
|
Provides OpenTelemetry instrumentation for [okhttp3](https://square.github.io/okhttp/).
|
|
|
|
## Quickstart
|
|
|
|
### Add these dependencies to your project
|
|
|
|
Replace `OPENTELEMETRY_VERSION` with the [latest
|
|
release](https://search.maven.org/search?q=g:io.opentelemetry.instrumentation%20AND%20a:opentelemetry-okhttp-3.0).
|
|
|
|
For Maven, add to your `pom.xml` dependencies:
|
|
|
|
```xml
|
|
<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:
|
|
|
|
```groovy
|
|
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.
|
|
|
|
```java
|
|
import io.opentelemetry.api.OpenTelemetry;
|
|
import io.opentelemetry.instrumentation.okhttp.v3_0.OkHttpTelemetry;
|
|
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 OkHttpTelemetry.builder(openTelemetry).build().newCallFactory(createClient());
|
|
}
|
|
|
|
//your configuration of the OkHttpClient goes here:
|
|
private OkHttpClient createClient() {
|
|
return new OkHttpClient.Builder().build();
|
|
}
|
|
}
|
|
```
