usage of fio2gnuplot for IOPS test

[j4care-christianhahn]

Hi !

I'm trying to do an IOPS test of my storage and wanted to create a graphical plot out of the results using fio2gnuplot but I cannot get any graphs. I'm using latest FIO (fio-3.37) but for some reason I cannot get an output that can be used by fio2gnuplot.
Here the sample command that I'm trying:

fio --name=test --rw=randread --bs=4k --size=1G --numjobs=1 --runtime=60 --time_based --group_reporting --output-format=json --output=fio_output.json --write_iops_log=test

could someone provide some samples how I can test my storage and format it so that fio2gnuplot can create a graphics.
