Ops for Developers - Monitor Your Java Application with Prometheus
summary
Prometheus captures JVM and container metrics while application-side instrumentation exposes meaningful business signals: Dropwizard Metrics and the Prometheus Java simpleclient surface JVM heap, GC and thread metrics; Hystrix metrics provide per-external-call counts, percentiles and circuit-breaker state (demo shows latency percentiles and GC CPU spikes under load). Custom collectors and Prometheus-style histograms are implemented for GC, Tomcat and DB pools; Hystrix exporter exists but is not yet on Maven Central. Recommendations: per-team Prometheus and instrument for load testing.
