nl_tokens: HISTOGRAM --------- Sample a histogram value . Histograms will produce metrics that describe the distribution of the recorded values namely the minimum maximum average count and the 75th 85th 95th and 99th percentiles . Optionally specify a list of * tags * to associate with the metric .
pl_tokens: function Histogram ( key , tags , host ) { Metric . call ( this , key , tags , host ) ; this . <mask> = Infinity ; this . max = - Infinity ; this . sum = 0 ; this . count = 0 ; this . samples = [ ] ; this . percentiles = [ 0.75 , 0.85 , 0.95 , 0.99 ] ; }
