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
