spring-boot-actuator
Production-grade monitoring, health checks, and metrics configuration for Spring Boot services using Actuator and Micrometer.
- Configure endpoint exposure, security policies, and dedicated management ports to isolate operational traffic from application routes
- Set up readiness and liveness health probes with custom indicators for orchestrator integration (Kubernetes, Cloud Foundry)
- Wire Micrometer exporters (Prometheus, OTLP, Wavefront) with application tags for cross-service correlation and SLO reporting
- Enable diagnostic endpoints (/startup, /conditions, /httpexchanges) for incident response and troubleshooting auto-configuration decisions
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.
