# Library Instrumentation for Apache Http client version 5.2
|
|
|
|
Provides OpenTelemetry instrumentation for [Apache Http Client 5.2](https://hc.apache.org/httpcomponents-client-5.2.x/).
|
|
|
|
## 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-apache-httpclient-5.2).
|
|
|
|
For Maven, add to your `pom.xml` dependencies:
|
|
|
|
```xml
|
|
<dependencies>
|
|
<dependency>
|
|
<groupId>io.opentelemetry.instrumentation</groupId>
|
|
<artifactId>opentelemetry-apache-httpclient-5.2</artifactId>
|
|
<version>OPENTELEMETRY_VERSION</version>
|
|
</dependency>
|
|
</dependencies>
|
|
```
|
|
|
|
For Gradle, add to your dependencies:
|
|
|
|
```groovy
|
|
implementation("io.opentelemetry.instrumentation:opentelemetry-apache-httpclient-5.2:OPENTELEMETRY_VERSION")
|
|
```
|
|
|
|
### Usage
|
|
|
|
The instrumentation library provides the class `ApacheHttpClientTelemetry` that has a builder
|
|
method and allows the creation of an instance of the `HttpClientBuilder` to provide
|
|
OpenTelemetry-based spans and context propagation:
|
|
|
|
```java
|
|
import io.opentelemetry.api.OpenTelemetry;
|
|
import io.opentelemetry.instrumentation.apachehttpclient.v5_2.ApacheHttpClientTelemetry;
|
|
import org.apache.hc.client5.http.classic.HttpClient;
|
|
import org.apache.hc.client5.http.impl.classic.HttpClientBuilder;
|
|
|
|
public class ApacheHttpClientConfiguration {
|
|
|
|
private OpenTelemetry openTelemetry;
|
|
|
|
public ApacheHttpClientConfiguration(OpenTelemetry openTelemetry) {
|
|
this.openTelemetry = openTelemetry;
|
|
}
|
|
|
|
// creates a new http client builder for constructing http clients with open telemetry instrumentation
|
|
public HttpClientBuilder createBuilder() {
|
|
return ApacheHttpClientTelemetry.builder(openTelemetry).build().newHttpClientBuilder();
|
|
}
|
|
|
|
// creates a new http client with open telemetry instrumentation
|
|
public HttpClient newHttpClient() {
|
|
return ApacheHttpClientTelemetry.builder(openTelemetry).build().newHttpClient();
|
|
}
|
|
}
|
|
```
