Class Summary

Class	Description
Clock	An abstraction for how time passes.
Clock.CpuTimeClock	A clock implementation which returns the current thread's CPU time.
Clock.UserTimeClock	A clock implementation which returns the current time in epoch nanoseconds.
Counter	An incrementing and decrementing counter metric.
Gauge<T>	A gauge metric is an instantaneous reading of a particular value.
HealthCheck	A health check for a component of your application.
HealthCheck.Result	The result of a HealthCheck being run.
HealthCheckRegistry	A registry for health checks.
Histogram	A metric which calculates the distribution of a value.
Meter	A meter metric which measures mean throughput and one-, five-, and fifteen-minute exponentially-weighted moving average throughputs.
MetricName	A value class encapsulating a metric's owning class and name.
MetricsRegistry	A registry of metric instances.
Timer	A timer metric which aggregates timing durations and provides duration statistics, plus throughput statistics via Meter.
TimerContext	A timing context.
VirtualMachineMetrics	A collection of Java Virtual Machine metrics.
VirtualMachineMetrics.BufferPoolStats	The management interface for a buffer pool, for example a pool of direct or mapped buffers.
VirtualMachineMetrics.GarbageCollectorStats	Per-GC statistics.
