Inconsency between cli output and gnuplot

[Erwan Velu <erwan@seanodes.com>]

My 1.23 fio ouput display :

  read : io=32,003MiB, bw=131MiB/s, iops=1,362, runt=250326msec
    slat (usec): min=13, max=145, avg=16.69, stdev= 3.39
    clat (msec): min=31, max=129, avg=46.94, stdev= 7.24

clat output of gnuplot reports units in msec. The clat gnuplot output 
show a msec label on the y axis but trace some usec.

slat cli reports values that doesn't match at all what is viewable from 
gnuplot output. Averagage is said to be 16 on the cli whereas the 
gnuplot trace shows 20 at min.
Max is said to be 145 for slat but displayed at 60 on the gnuplot.
Slat is also said to be usec on the cli but shown as msec on the y axis 
of the gnuplot.

Complete archive showing that could be downloaded at

It seems that units may vary from the cli output regarding the range of 
results. I have some case where clat is shown in usec instead of msec. 
Maybe that what confuse the gnuplot output.
Like in :
  write: io=32,003MiB, bw=124MiB/s, iops=1,294, runt=263681msec
    slat (usec): min=12, max=71, avg=15.43, stdev= 2.72
    clat (usec): min=663, max=1,537K, avg=49431.63, stdev=108787.82
    bw (KiB/s) : min=    0, max=171311, per=99.91%, avg=127152.93, 
stdev=21619.46
