Package org.mockserver.metrics

Class JvmMetricsCollector

java.lang.Object

org.mockserver.metrics.JvmMetricsCollector

All Implemented Interfaces:

io.prometheus.metrics.model.registry.MultiCollector

public class JvmMetricsCollector
extends Object
implements io.prometheus.metrics.model.registry.MultiCollector

Exposes JVM runtime metrics (heap / non-heap memory, threads, GC) as Prometheus gauges so the dashboard Metrics view and Grafana can chart MockServer's process health. Registered once alongside BuildInfoCollector when metrics are enabled.

Reads only JDK java.lang.management MX beans — no extra dependency — and is read-only/allocation-light, so scraping it has negligible overhead. Values are sampled fresh on each collect() (i.e. each scrape).
