NAME

latencybins − comp utility for scripts/latency-histogram

SYNOPSIS

Usage:
Read availablebins pin for the number of bins available.
Set the maxbinnumber pin for the number of ± bins.
Ensure maxbinnumber <= availablebins
For maxbinnumber = N, the bins are numbered:
−N ... 0 ... + N bins
(the −0 bin is not populated)
(total effective bins = 2*maxbinnumber +1)
Set nsbinsize pin for the binsize (ns)
Iterate:
Set index pin to a bin number: 0 <= index <= maxbinnumber.
Read check pin and verify that check pin == index pin.
Read output pins:
pbinvalue is count for bin = +index
nbinvalue is count for bin = −index
pextra is count for all bins > maxbinnumber
nextra is count for all bins < maxbinnumber
latency-min is max negative latency
latency-max is max positive latency

If index is out of range ( index < 0 or index > maxbinnumber)
then pbinvalue = nbinvalue = −1.
The reset pin may be used to restart.
The latency pin outputs the instantaneous latency.

Maintainers note: hardcoded for MAXBINNUMBER==1000
