EXPERIMENTAL. Calculates percentiles over numbers. Returns one event with a field for each of the percentiles specified in the percentiles parameter. Fields are named like by appending _ (underscore) to the values specified in the percentiles parameter. For example the event could contain the fields _50, _75 and _99. Input can be a number OR the special format for the moment sketch "[min,max,Σv⁰,Σv¹,Σ,²,...]" used for client-side computed sketches.
|string||false||Prefix of output fields.|
|string||true||Specifies the field for which to calculate percentiles. The field must contain numbers. [a]|
|number||false||Specifies the order of the underlying polynomial.|
|number||false||Specifies which percentiles to calculate.|
Calculate 50,75,99, and 99.9 percentiles for events with the field responsetime:
percentile(field=responsetime, percentiles=[50, 75, 99, 99.9])
In a timechart, calculate percentiles for both of the fields r1 and r2:
