Description
Interface Summary | |
---|---|
MetricListener | This interface allows instances of classes which implement this interface to receive MetricEvents from instances which are sources of MetricEvents. |
Monitorable | Interface which is to be implemented by any classes which are capable of being monitored. |
Class Summary | |
---|---|
Metric | An instance of this class represents a measurable quantity within a monitoring system. |
MetricDefinition | An instance of this class is a decription of a measurable quantity within a monitoring system. |
MetricEvent | An instance of this class represents an metric event. |
This package contains classes and interfaces which are used
to monitor resources.
The most important classes and interfaces in this package are
Metric
,
MetricEvent
,
MetricListener
, and
Monitorable
.
An instance of the class Metric
represents a measurable quantity within a monitoring system and is used to
specify a measurable quantity.
An instance of the class
MetricEvent
represents the measured value of a quantity measured by a monitoring system
and is used to specify to interested parties that a measurement of a
quantity corresponding to a Metric
has taken place.
The interface
MetricListener
is implemented by classes that want to be informed of
MetricEvents
and is used to
inform instances of such classes of
MetricEvents
.
The interface Monitorable
is implemented by classes that want to be monitored for
MetricEvents
and is used to
inform interested parties of such events.
