Implementing OpenTelemetry for Spring Boot Microservices

source : cloudblogs.microsoft.com/

In today’s complex microservices environments, monitoring and tracing are crucial for maintaining system health and diagnosing issues. OpenTelemetry provides a unified way to collect telemetry data from distributed systems. This guide will walk you through setting up OpenTelemetry in your Spring Boot microservices, complete with comprehensive explanations and code examples in Java.

1. Introduction to OpenTelemetry

OpenTelemetry is an open-source project aimed at providing a standardized way to collect and instrument telemetry data (traces, metrics, logs) from applications. It supports a variety of backends like Jaeger, Zipkin, and Prometheus.

2. Prerequisites

Before diving into the implementation, ensure you have the following:

• Java Development Kit (JDK) 11 or later
• Maven or Gradle
• Basic understanding of Spring Boot and microservices architecture

3. Setting Up Your Spring Boot Application

First, let’s create a simple Spring Boot application. Use Spring Initializr (https://start.spring.io/) to generate a new project with the following dependencies:
