# Spring Boot Actuator Skill ## Overview - Deliver production-ready observability for Spring Boot services using Actuator endpoints, probes, and Micrometer integration. - Standardize health, metrics, and diagnostics configuration while delegating deep reference material to `references/`. - Support platform requirements for secure operations, SLO reporting, and incident diagnostics. ## When to Use - Trigger: "enable actuator endpoints" – Bootstrap Actuator for a new or existing Spring Boot service. - Trigger: "secure management port" – Apply Spring Security policies to protect management traffic. - Trigger: "configure health probes" – Define readiness and liveness groups for orchestrators. - Trigger: "export metrics to prometheus" – Wire Micrometer registries and tune metric exposure. - Trigger: "debug actuator startup" – Inspect condition evaluations and startup metrics when endpoints are missing or slow. ## Quick Start ```xml <!-- Maven --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> ``` ```gradle // Gradle dependencies { implementation "org.springframework.boot:spring-boot-starter-actuator" } ``` After adding the dependency, verify endpoints respond: ```bash curl http://localhost:8080/actuator/health curl http://localhost:8080/actuator/info ``` ## Instructions ### 1.
