Smokeping_matchers_ExpLoss: exponential weighting matcher for packet loss
NAME
Smokeping::matchers::ExpLoss - exponential weighting matcher for packet loss with RMON-like thresholds
DESCRIPTION
Match against exponential weighted average of last samples, thus new values are more valuable as old ones. Two thresholds - rising and falling - produce hysteresis loop like in RMON alert subsystem. If the average reaches the ``rising'' threshold, matcher go to the ``match'' state and hold It until the average drops under the ``falling'' threshold.Call the matcher with the following sequence:
type = matcher pattern = CheckLoss(hist => <hist>, rising=><rising> \ [,falling => <falling>] [,skip=><stat>] [,fast=><fast>])
