I feel stupid for asking this because it seems that MYSQL code isn't working the way that I think it should work.
Basically I wrote code like this:
select * from `Test_DC_Trailer` HAVING max(DR_RefKey);

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.
