A little lib for turning hdr-histogram-js to objects
npm install hdr-histogram-percentiles-obj```
npm install --save hdr-histogram-percentiles-obj
`js
const histPercentileObj = require('hdr-histogram-percentiles-obj')
const Histogram = require('hdr-histogram-js')
const histogram = hdr.build({
lowestDiscernibleValue: 1,
highestTrackableValue: 100
})
const total = 0
// record some histogram data...
// total++...
const result = histPercentileObj.histAsObj(histogram, total)
const resultWithPercentiles = histPercentileObj.addPercentiles(histogram, histPercentileObj.histAsObj(histogram, total))
histPercentileObj.percentiles.forEach((p) => {
const key = p${p}.replace('.', '_')${p}%
console.log(, resultWithPercentiles[key])`
})
hdr-histogram-percentiles-obj has two utility functions to use
* histogram: A hdr-histogram-js object you want to get some values from in a js objecttotal
* : the total amount recorded by the histogram, optional
Returns a json object with the min, max, average (mean) and stddev
* histogram: A hdr-histogram-js object you want to retrieve the percentiles fromhistAsObjResult
* : the result returned when histAsObj is called on some hdr-histogram-js object
Returns the histAsObjResult with the percentiles properties added. Percentile properties are named pNN_DD, for the NN.DD% percentile. Eg., the 99th percentile is p99, while the 99.99th percentile is p99_99`.
An array listing the percentiles that hdr-histogram-percentiles-obj adds, as numbers.
