JVM Metrics ​

This page documents Prometheus metrics exposed by the JVM instrumentation module of the Prometheus Java Client Library inside of Yellowbrick components.

Purpose ​

JVM metrics are essential for understanding the behavior and health of long-running Java processes. They cover a wide range of subsystems:

  • Memory usage (heap, non-heap, and memory pools)
  • Garbage collection frequency and duration
  • JIT compilation time
  • Thread activity and contention
  • Class loading dynamics
  • Process-level system statistics (CPU usage, open file descriptors)
  • Native memory tracking

These metrics help detect memory leaks, GC pressure, thread exhaustion, and performance degradation across critical components.
