Smokeping_matchers_Median: Find persistant changes in latency
Smokeping::matchers::Median - Find persistant changes in latency
OVERVIEWThe 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.
DESCRIPTIONCall the matcher with the following sequence:
type = matcher pattern = Median(old=>x,new=>y,diff=>z)
