Class Statistics

java.lang.Object
  net.sf.infrared.agent.Statistics

All Implemented Interfaces:

Serializable

public class Statistics

extends Object

implements Serializable

This class is used to keep track of the performance metrics that are collected. An instance of Statistics object is held in a static map in the StatisticMgr. StatisticsCollector also holds a private instance of this class to collect statistics for each operation in the request. StatisticsCollector then merges this instance of Statistics object with the statistics object held by StatisticsMgr. The aggregation of Statistics collected by StatisticsCollector with the StatisticsManager happens based on the collection strategy viz Local and Remote.
