fio2gnuplot issue

[Saeed Tea]

I'm trying generate graphs with logs create by fio using fio2gnu and 
keep getting this error when generating graphs for iops or bandwidth:

1 files Selected with pattern '*_iops.log'
|-> 4k.results_iops.log

Running gnuplot Rendering
"/usr/share/fio//math.gpm", line 25: no datablock named $1

"/usr/share/fio//graph2D.gpm", line 25: no datablock named $1


Rendering traces are available in the current directory

Checking the directory listing only shows this file:

$3.png

Am I missing something in fio profile??� Here's a snippet:

[global]
rw=randread
ioengine=posixaio
iodepth=64
size=10g
direct=0
buffered=1
startdelay=5
ramp_time=5
runtime=20
time_based
disk_util=0
clat_percentiles=0
write_bw_log=4k.results
write_iops_log=4k.results
write_lat_log=4k.results
per_job_logs=0

This is with fio 2.12

This happens because you have gnuplot 5 and it dropped support for the
$1 way of passing arguments on the command line (see
http://stackoverflow.com/a/31815067/4513656 ). To get around this both
the .gpm and and fio2gnuplot would have to be rewritten to use a
different means of passing parameters in. I'm not sure any method
beyond using environment variables would work for both old and new
versions of gnuplot...

Trying again but with a different email address for the original author.

Thanks!  I suspected it must've been something with gnuplot because it 
seems to work with Ubuntu 15.xx (running Gnuplot 4.xx) and breaks with 
Ubuntu 16.xxx (running Gnuplot 5.xx).

I tried contacting Erwan for an answer on a possible update but gotten 
no response.

I've posted some changes that seem to get things going under gnuplot 5
for me. Could you check to see if
https://github.com/axboe/fio/pull/208 lets things work for you on
Ubuntu 16.04?

I ran a couple of tests with your rev of fio2gnuplot and it seems to 
work fine with gnuplot 5.x on ubuntu 16.x - thanks~

Thanks for following up. Since Jens merged this hopefully this will
help others too (I notice there's an Arch Linux bug that sounds
similar).
