Interface Summary

Interface	Description
DiscardableMetricsProvider	A MetricsProvider that has the ability to discard to provided metrics.
DoubleGauge	A DoubleGauge is {link Gauge} where a particular double value is read instantaneous.
DoubleProbeFunction<S>	A ProbeFunction that provides a double value and can be used to create a probe using MetricsRegistry#register(Object, String, DoubleProbeFunction)
Gauge	A Gauge is Metric where a particular value is read instantaneous.
LongGauge	A LongGauge is Gauge where a particular long value is read instantaneous.
LongProbeFunction<S>	A ProbeFunction that provides a long value and can be used to create a probe using MetricsRegistry#register(Object, String, LongProbeFunction)
Metric	A Metric is a 'quantitative measure' of something for example the number of operations pending, number of operations per second being executed etc.
MetricsProvider	To be implemented by an object that can provide metrics (so has a bunch of probes).
MetricsRegistry	The MetricsRegistry is responsible for recording all kinds of Hazelcast/JVM specific information to help out with issues like performance or stability problems.
ProbeFunction	A marker interface.

Enum Summary

Enum	Description
ProbeLevel	With the probe level one can control which probes are being tracked by the MetricsRegistry and which ones are not.

Annotation Types Summary

Annotation Type	Description
Probe	Annotation that can be placed on a field or method of an object to indicate that it should be tracked by the MetricsRegistry when the MetricsRegistry.scanAndRegister(Object, String) is called.
