..::lib::Smokeping::matchers::MediaSmok..::lib::Smokeping::matchers::Median(3)

NAME
       Smokeping::matchers::Median - Find persistant changes in	latency

OVERVIEW
       The idea	behind this matcher is to find sustained changes in latency.

       The median matcher takes	a number of past median	latencies. It splits
       the latencies into two groups (old and new) and again finds the median
       for each	groups.	If the difference between the two medians is bigger
       than a certain value, it	will give a match.

DESCRIPTION
       Call the	matcher	with the following sequence:

	type = matcher
	pattern	=  Median(old=>x,new=>y,diff=>z)

       This will create	a matcher which	consumes x+y latency-datapoints,
       builds the two medians and the matches if the difference	between	the
       median latency is larger	than z seconds.
