Pretty graphs

Pretty graphs

[Mauricio Tavares]

Somewhat-related fio question: how do you make graphs of you results?
For instance, I would like to show, say iops for 4K from write,
randwrite, read, randread on the same drive comparing fio+libaio,
fio+spdk, spdk+perf. This smells like a 3D graph thingie, but my lack
of skills on excel/libre office does not help me. gnuplot?

I wrote an application note that parses FIO performance data in real
time(ish) and displays it in a nice virtual oscilloscope interface
(QPS): https://youtu.be/LivVBa61ox0?t=113
It currently requires a Quarch power module, but this may be waived in
the future.

Quarch's python package contains a nice parser that should make it
quite straightforward to plot FIO's data (even in real time):

That's neat! On a similar note, I've had conversations with colleagues
recently about the need for, and novelty of, a Prometheus exporter for
fio. IMHO the ability to export histogram'd stats over time would be
especially useful.

Thank you for all the answers. I do think Pedro's package is quite
interesting, but I am not trying to plot in real time. All I want to
do is something like this https://imgur.com/a/afWwFHO, which I am
having a hard time getting it to work in gnuplot. I believe
fio-visualizer may not do the trick; at least I was not able to do so.
