Creating additional subsegments - Amazon X-Ray
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Creating additional subsegments

In the user model class, the application manually creates subsegments to group all downstream calls made within the saveUser function and adds metadata.

Example src/main/java/scorekeep/ - Custom subsegments
import com.amazonaws.xray.AWSXRay; import com.amazonaws.xray.entities.Subsegment; ... public void saveUser(User user) { // Wrap in subsegment Subsegment subsegment = AWSXRay.beginSubsegment("## UserModel.saveUser"); try {; } catch (Exception e) { subsegment.addException(e); throw e; } finally { AWSXRay.endSubsegment(); } }
