Interface Summary

Interface	Description
AbsoluteCounter	A AbsoluteCounter is a marker interface for a Counter that resets is value to 0 every time AbsoluteCounter.getValue() is called.
Counter	A Counter is a Instrument that can only increase in value.
DerivedCounter	A DerivedCounter is a marker interface for a Gauge that should be treated as a Counter in terms of rate of change recording but that allows is value to decrease.
ExternalValue	The ExternalValue interface is used to provide Instrument values from some external piece of code.
Gauge	A Gauge is a Instrument that can oscillate its value over time.
Instrument	An Instrument is a "named" monitored object that can return a value.
InstrumentRegistry	This is a glorified Map/Set of Instrument's.
RegistryConfiguration	This configures information about the registry.

Class Summary

Class	Description
AbsoluteAtomicCounter	An AbsoluteCounter is a Counter that resets its value to zero every time AbsoluteAtomicCounter.getValue() is called.
AtomicCounter	An implementation of Counter that uses an AtomicLong for its value.
AtomicGauge	A simple implementation of Gauge
CachedExternalValue	This class allows values to be computed on as as needed basis and also cache the values for a certain length of time.
DefaultInstrumentRegistry	This is a glorified Map/Set of Instrument's.
DerivedAtomicCounter	An implementation of DerivedCounter
ExternalCounter	An ExternalCounter is a Counter that bases its value of an ExternalValue value
ExternalGauge	An ExternalGauge is a Gauge that bases its value of an ExternalValue value
InstrumentToStringBuilder	A string builder for Instruments
SimpleCounter	This instrument is a counter designed for situations where thread safety is not required and hence does not have the overhead of a synchronized counter.
SimpleTimer	This instrument is a timer designed for situations where thread safety is not required and hence the overhead of a synchronized value is removed.
