Interface Summary

Interface	Description
DoubleGauge	A DoubleGauge is a Gauge where a particular double value is read instantaneously.
DoubleProbeFunction<S>	A ProbeFunction that provides a double value and can be used to create a probe using MetricsRegistry.registerStaticProbe(Object, String, ProbeLevel, LongProbeFunction)
DynamicMetricsProvider	Interface to be implemented by the classes that expose metrics in a dynamic fashion.
Gauge	A Gauge is a Metric where a particular value is read instantaneously.
LongGauge	A LongGauge is a Gauge where a particular long value is read instantaneously.
LongProbeFunction<S>	A ProbeFunction that provides a long value and can be used to create a probe using MetricsRegistry.registerStaticProbe(Object, String, ProbeLevel, 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.
MetricsExtractor	An interface that extracts the metrics from the objects collected by the DynamicMetricsProvider implementations.
MetricsPublisher	Represents an object which publishes a set of metrics to some destination.
MetricsRegistry	The MetricsRegistry is a registry of various Hazelcast/JVM internal information to help out with debugging, performance or stability issues.
MetricTagger	Interface to be used for tagging a metric.
MetricTaggerSupplier	Interface used to get a MetricTagger based on its namespace.
ProbeAware	Interface that can return a Probe instance.
ProbeFunction	A marker interface.
StaticMetricsProvider	To be implemented by an object that can provide metrics (so has a bunch of probes).

Class Summary

Class	Description
MetricsUtil	A utility to escape and parse metric key in tagged format:

Enum Summary

Enum	Description
MetricTarget	Enum representing the target platforms of the metrics collection.
ProbeLevel	With the probe level one can control which probes are being tracked by the MetricsRegistry and which ones are not.
ProbeUnit	Measurement unit of a Probe.

Annotation Types Summary

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

Package com.hazelcast.internal.metrics Description

Contains the Hazelcast Metrics. The MetricsRegistry records all kinds of internal metrics of Hazelcast, the OS, the JVM etc.
