Spring Boot Actuator

This handles the operational side of Spring Boot services: health checks, metrics endpoints, and secure management ports using Actuator and Micrometer. You'll reach for it when setting up readiness probes for Kubernetes, exposing Prometheus metrics, or isolating management traffic on a separate port with proper authentication. The skill covers the full progression from basic health endpoints to custom health indicators and dedicated security chains using EndpointRequest matchers. One thing worth noting is the emphasis on keeping sensitive endpoints like /env and /heapdump locked down, which is easy to overlook when you're just trying to get observability working. The reference materials include endpoint catalogs and examples for different export targets, so you're not hunting through Spring docs during an incident.

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.
