opentelemetry-java-instrumentation/instrumentation/spring/spring-webmvc-5.3/library

Library Instrumentation for Spring Web MVC version 5.3 and higher

Provides OpenTelemetry instrumentation for Spring WebMVC controllers.

Quickstart

Add these dependencies to your project.

Replace SPRING_VERSION with the version of spring you're using.

• Minimum version: 5.3

Replace OPENTELEMETRY_VERSION with the latest release.

For Maven add the following to your pom.xml:

<dependencies>
  <!-- OpenTelemetry instrumentation -->
  <dependency>
    <groupId>io.opentelemetry.instrumentation</groupId>
    <artifactId>opentelemetry-spring-webmvc-5.3</artifactId>
    <version>OPENTELEMETRY_VERSION</version>
  </dependency>

   <!-- OpenTelemetry exporter -->
   <!-- replace this default exporter with your OpenTelemetry exporter (ex. otlp/zipkin/jaeger/..) -->
   <dependency>
    <groupId>io.opentelemetry</groupId>
    <artifactId>opentelemetry-exporter-logging</artifactId>
    <version>OPENTELEMETRY_VERSION</version>
  </dependency>

  <!-- required to instrument Spring WebMVC -->
  <!-- this artifact should already be present in your application -->
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>SPRING_VERSION</version>
  </dependency>

</dependencies>

For Gradle add the following to your dependencies:

// OpenTelemetry instrumentation
implementation("io.opentelemetry.instrumentation:opentelemetry-spring-webmvc-5.3:OPENTELEMETRY_VERSION")

// OpenTelemetry exporter
// replace this default exporter with your OpenTelemetry exporter (ex. otlp/zipkin/jaeger/..)
implementation("io.opentelemetry:opentelemetry-exporter-logging:OPENTELEMETRY_VERSION")

// required to instrument Spring WebMVC
// this artifact should already be present in your application
implementation("org.springframework:spring-webmvc:SPRING_VERSION")

Features

SpringWebMvcTelemetry

SpringWebMvcTelemetry enables creating OpenTelemetry server spans around HTTP requests processed by the Spring servlet container.

Usage in Spring Boot

Spring Boot allows servlet Filters to be registered as beans:

import io.opentelemetry.api.OpenTelemetry;
import io.opentelemetry.instrumentation.spring.webmvc.v5_3.SpringWebMvcTelemetry;
import javax.servlet.Filter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class SpringWebMvcTelemetryConfiguration {

   @Bean
   public Filter telemetryFilter(OpenTelemetry openTelemetry) {
      return SpringWebMvcTelemetry.create(openTelemetry).createServletFilter();
   }
}
