okay bestie, you found the SmokePing manual page ..::lib::Smoke...hers::Medratio(3) and the star of the show is Smokeping::matchers::Medratio 💅✨

💖 NAME 💖

Smokeping::matchers::Medratio — detect changes in the latency median. periodt. 👑

🦋 OVERVIEW 🦋

The Medratio matcher establishes a historic median latency over several measurement rounds. It compares that median against a second median latency value, again built over several rounds of measurement.

Because it’s looking at the median, this matcher is largely immune to spikes and will only react to long-term developments. no cap, it’s giving patient main character energy 🧚

✨ DESCRIPTION ✨

Call the matcher with this sequence, bestie:

type = matcher
pattern =  Medratio(historic=>a,current=>b,comparator=>o,percentage=>p)

Then the options are:

• historic — the number of values to use for building the 'historic' median. 🎀
• current — the number of values to use for building the 'current' median. 🦋
• comparator — which comparison operator should be used to compare current/historic with percentage. 💅
• percentage — right hand side of the comparison. 🌸

Here’s the little timeline vibe:

old <--- historic ---><--- current ---> now

🌸 EXAMPLE 🌸

Take the 12 last median values. Build the median out of the first 10 and the median from the other 2 values. Divide the results and decide if it is bigger than 150 percent. 👑

Medratio(historic=>10,current=>2,comparator=>'>',percentage=>150);

med(current)/med(historic) > 150/100

This means the matcher will activate when the current latency median is more than 1.5 times the historic latency median established over the last 10 rounds of measurement. that’s the threshold, bestie — not a drill 💀🔥
