Class EventCountStage

java.lang.Object
  |
  +--ostore.oil.EventCountStage

All Implemented Interfaces:

EventHandlerIF

public class EventCountStage

extends Object

implements EventHandlerIF

EventCountStage watches for events of certain types, and counts them. Pretty simple. To use, create an EventCountStage stage in the config file, and in the initargs sections have the line:

events Event1 Event2 . . . EventN

where events 1 through N are the events you want to keep track of. When you want to know the count of a certain even, send out a EventCountRequestMsg, and this stage will send you back an EventCountMsg with the count. Currently this functionality is pretty simple, but possibly later we can add support for rates, thresholds, etc.
