These classes define the statistics package used extensively throughout the I2P router  both for adaptive operation of the router and for debugging.

Interface Summary Interface Description RateSummaryListener Receive the state of the rate when its coallescedStatLog Component to be notified when a particular event occurs 
Class Summary Class Description BufferedStatLog Note  if no filter is defined in stat.logFilters at startup, this class will not be instantiated  see StatManager.Frequency Manage the calculation of a moving average event frequency over a certain period.FrequencyStat coordinate an event frequency over various periodsPersistenceHelper Output rate data.Rate Simple rate calculator for periodically sampled data points  determining an average value over a period, the number of events in that period, the maximum number of events (using the interval between events), and lifetime data.RateAverages Storage space for computations of various averages.RateStat coordinate a moving rate over various periodsStatManager Coordinate the management of various frequencies and rates within I2P components, both allowing central update and retrieval, as well as distributed creation and use.
