Application Performance Monitoring (APM)

To ensure high availability and performance, this application is actively monitored using a modern observability stack composed of Spring Boot Actuator and Micrometer.

This setup provides detailed, real-time insights into the performance of critical operations, particularly the latency of API calls and service method executions.

Monitoring Architecture 🏗️

The monitoring system operates in two distinct stages:

  1. Data Collection (Actuator): The Spring Boot Actuator module exposes operational information about the running application — health, loggers, info.

  2. Instrumentation (Micrometer): We use Micrometer, an application metrics facade, to instrument our code. Key methods are wrapped with Timer metrics, which record the duration and count of every execution, providing a clear view of API performance.
