Package de.is24.util.monitoring

Interface Summary

Interface	Description
Historizable	Represents a single Value of a historizable entity.
MonitorPlugin
Monitors.Factory<T>
MultiValueProvider	MultiValueProviders exposes a list of State instances on demand,
Reportable	The building blocks of the InApplicationMonitor class are Reportables.
ReportableObserver	Classes can register themselves as ReportableObserver if they want to be notified about new reportables that are registered on the InApplicationMonitor Implementations should overwrite toString(), to provide some context to CorePlugin.getRegisteredReportableObservers()
ReportVisitor	ReportVisitors are used to read content from the registered Reportable instances of the InApplicationMonitor

Class Summary

Class	Description
AbstractMonitorPlugin	Plugin base class with suitable equals and hashCode implementations and default handling for HighRate and SingleEvent.
AbstractStateValueProvider	Convenience implementation of StateValueProvider.
CorePlugin	This plugin represents the former core functionality of InApplicationMonitor, on a way to a more flexible implementation by plugins, to simplify testing and the first step on the way fo a more dependency injection friendly implementation.
Counter	Counters are used to count events.
HistorizableList	This list manages ordering and discarding of registered Historizables with the same name.
InApplicationMonitor	This is the central class of appmon4j. appmon4j is a lightweight, easy to use in application monitoring system allowing measurements of "real traffic" performance values in high throughput java applications. This class is an "old school" singleton, which is accessed by using the static getInstance() method.
Math	Util method for Maths that are not provided by standard libraries.
Monitors<T extends Reportable>	Wrapper class for monitors.
PerfTimer	Helper class to perform timer measurements.
PerfTimer.DefaultPerfTimer	A timer implementing the default measurement behaviour based on system time.
PerfTimer.NoPerfTimer	A timer that always returns 0 on measurements for performance reasons (null object).
PerfTimer.PerfMonitor	A timer providing an interface for submitting measurements to InApplicationMonitor.
SimpleHistorizable	This is a default Implementation of Historizable supplied for convenience.
SimpleStateValueProvider	Implements StateValueProvider for easily adding a key - value pair to our inapplicationmonitor.
State
StateValueProvider	StateValueProviders allow access to a numeric value (long), that is already available in the application
TestingInApplicationMonitor
Timer	Currently a subclass of counter although this makes no sense and should be refactored Timers count and measure timed events.
