SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Implement end-to-end observability for Spring Boot 4 microservices by integrating health probes, metrics, tracing, and high-performance logging to improve reliability and debuggability in distributed systems.

Core Features & Use Cases

  • Health and readiness/liveness probes via Spring Actuator for Kubernetes readiness and overall health visibility.
  • Metrics collection with Micrometer and Prometheus, plus OTLP export to external collectors for tracing integration.
  • Distributed tracing with OpenTelemetry across services, enabling automatic context propagation and correlation.
  • High-performance, asynchronous logging with Log4j2 and Disruptor to minimize GC impact in production.

Quick Start

Configure Actuator endpoints, Micrometer metrics, and OpenTelemetry tracing in a Spring Boot 4 application, then verify observability dashboards.

Frequently Asked Questions about observability

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I configure OpenTelemetry tracing in Spring Boot 4 microservices?▼

Configure OpenTelemetry tracing in Spring Boot 4 by setting up OTLP export to external collectors, enabling automatic context propagation and correlation across distributed microservices for end-to-end visibility.

What is the best way to set up Kubernetes health probes with Spring Actuator?▼

Set up Kubernetes health probes by configuring Spring Actuator endpoints for readiness and liveness, providing overall health visibility and proper probe configuration for your microservices across different environments.

How do I collect Prometheus metrics using Micrometer in Spring Boot 4?▼

Collect Prometheus metrics in Spring Boot 4 by integrating Micrometer to capture application metrics, then expose them via Actuator endpoints for monitoring and export to external metric collectors.

Can I use Log4j2 with Disruptor for asynchronous logging in Spring Boot?▼

Yes, you can use Log4j2 with Disruptor for high-performance asynchronous logging in Spring Boot, minimizing garbage collection impact and improving throughput in production environments.

Does Spring Boot 4 Actuator support both metrics and health checks together?▼

Yes, Spring Boot 4 Actuator supports both metrics and health checks together, allowing you to configure Micrometer Prometheus metrics, Kubernetes readiness probes, and overall health visibility within a single integration.
