Answer from AI
In the Spring Framework, the following components and mechanisms are used for monitoring and tracing applications:
-
Spring Actuator: provides ready endpoints for monitoring application status, metrics, bean information, health, etc.
-
Micrometer: a library for collecting metrics, integrates with Spring Boot Actuator, and supports many monitoring systems (Prometheus, Graphite, Datadog, etc.).
-
Spring Cloud Sleuth: adds distributed tracing, automatically creating and passing trace identifiers (traceId, spanId) between services.
-
Integration with Zipkin or Jaeger: for visualization and analysis of distributed traces.
-
Logging with MDC (Mapped Diagnostic Context): allows associating logs with specific requests or sessions for easier debugging.
-
AOP (Aspect-Oriented Programming): used for injecting monitoring and tracing code without changing business logic.
Example of using Spring Actuator to get metrics:
// In application.properties
management.endpoints.web.exposure.include=health,metrics,prometheus
// After starting the application, metrics can be accessed at /actuator/metrics
Thus, the combination of Actuator, Micrometer, and Sleuth provides a powerful and flexible toolkit for monitoring and tracing in Spring applications.
