Package org.ow2.clif.datacollector.lib

Class InjectorDataCollector

  • All Implemented Interfaces:
    org.objectweb.fractal.api.control.BindingController, DataCollectorAdmin, DataCollectorWrite
    public class InjectorDataCollector
extends AbstractDataCollector
    Data collector for load-injectors generating ActionEvent events. statistics: - time frame, i.e. ellapsed time since previous getStat() call - average reponse time during this time frame - max response time during this time frame - min response time during this time frame - number of actions during this time frame - throughput (number of actions/sec) during this time frame - number of error occurrences during this time frame - error rate (number of error/sec) during this time frame - response time standard deviation
