Welcome to the Metrics
summary
Shows how to instrument Spring Boot apps with Spring Boot + Micrometer and Actuator to expose business-level health and custom counters, push them to VMware Tanzu Observability (Wavefront) (Prometheus optional), and build dashboards that aggregate metrics from 10 running services. Demonstrates dashboards that surface a sudden drop in transactions, zooms to per-service memory and request metrics, finds a memory leak in one microservice, and restores throughput after a fix. Includes examples of tagging, dynamic discovery, and filtering last-five-minute windows.
