..::lib::Smoke...tchers::Median(3)

✨ NAME ✨

okay so this is the ..::lib::Smoke...tchers::Median(3) page from the SmokePing manual, and the matcher is literally called Smokeping::matchers::Median — it finds persistent changes in latency. slay. 💅

🦋 OVERVIEW 🦋

The whole idea behind this matcher? Finding sustained changes in latency. That's the assignment, bestie. ✨

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 group. If the difference between the two medians is bigger than a certain value, it will give a match. No cap. 🫶

🌸 DESCRIPTION 🌸

Call the matcher with this exact sequence:

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

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