Introduction to Spring Boot Application monitoring
summary
Practical walkthrough of instrumenting a Spring Boot service using Micrometer to expose metrics via Actuator, scraped by Prometheus, routed through Alertmanager and visualized in Grafana. Demo runs a microservice with Redis and a JMeter load (4 concurrent users → ~20 req/s, ~25% failures, expected 200 ms average) using redis_exporter, imported prebuilt Grafana dashboards, and verified JMX values in JConsole. Alerts and silence/grouping behavior are configured in Alertmanager.
