client_http.all_svc_time histogram:
         13/1.017352 13 116.178383
         20/1.943709 212 1298.388363
         26/3.069709 731 3238.304286
         30/4.050593 868 3098.425220
         33/4.938498 1099 3336.450978
         (1) (2) (3) (4)

Default format for histogram dumps is:
        1) histogram bin number or id
        2) minimum value that belongs to to the bin (left_border)
        3) number of values in the bin (count)
        4) count / (right_border - left_border)

See statHistBinDumper() and statHistDump() functions for details.

I am not sure what the exact physical meaning of (4) is. Looks like some
kind of weighted count (weighted to reflect the bin size). I would not be
surprised if it meant to print something else. The good thing is that a
simple Perl script can convert printed values to whatever you need for
your application.
