Constructor Detail
SlicingMeasurementConsumer
public SlicingMeasurementConsumer(long tick, boolean keepMeasurements, int maxQueue, SliceConsumer sliceConsumer)(Code)
Creates a new instance with internal timer.
Parameters:
  tick - Slice size in milliseconds
Parameters:
  keepMeasurements - If true individual measurements are reported, only aggregated values otherwise
Parameters:
  maxQueue - Maximum number of slices pending to be consumed. 0 - no limit. If sampling ratio is higher thanconsuming ration then excessive slices will be dropped with a notice on console.



SlicingMeasurementConsumer
public SlicingMeasurementConsumer(long tick, boolean keepMeasurements, int maxQueue, SliceConsumer sliceConsumer, Timer timer)(Code)
Creates a new instance with internal timer.
Parameters:
  tick - Slice size in milliseconds
Parameters:
  keepMeasurements - If true individual measurements are reported, only aggregated values otherwise
Parameters:
  maxQueue - Maximum number of slices pending to be consumed. 0 - no limit. If sampling ratio is higher thanconsuming ration then excessive slices will be dropped with a notice on console.
Parameters:
  timer - Timer to use for slicing metrics and passing them to slice consumer. If it is null then an internal timer iscreated.
