Hi,
I'm trying to understand the "loops" feature.
I have jobfile that I would like to loop round a number of times:-
{jobfile.fio}
[global]
ioengine=libaio
direct=1
[job1]
rw=randrw
rwmixread=70
bsrange=4k-128k
iodepth=4
runtime=3m
filename=/dev/sdm
size=4G
time_based
offset=0
[job2]
stonewall
rw=write
bs=512K
size=12G
filename=/dev/sdm
iodepth=1
timeout=5m
offset=20G
{/jobfile.fio}
So above I have a random read/write section followed by a sequential
write section. I would like to loop round this for x number of times,
for example randrw, seqw, randrw, seqw, randrw, etc. I've tried using
the "loops=x" option in the global section, but all this does is loop
each job before moving onto the next, at the moment it does randrw,
randrw, seqw, seqw.
Along with the above I was hoping that with the run status group
report at the end of the run, it would give the average of each of
those runs with the received min and max values:-
Run status group 1 (all jobs):
WRITE: io=8192.0MB, aggrb=56333KB/s, minb=56333KB/s, maxb=56333KB/s,
mint=148909msec, maxt=148909msec
but at the moment the "minb" and "maxb" have the same values. Ideally
it would give the max and min values for each of those loops of that
particular job, along with the average.
Is this possible from within the jobfile?
Thanks,
Gavin
Hi, Martin,
I met the same problem with you, when I wanted to test performance for
one 15K SAS drive. I wrote one tool myself, called it 'fiox', which is a
simple fio wrapper that can support variables in normal fio
configurations. I didn't plan to publish is since it's playtoy and only
used by myself for once currently, but it might help in some way
(hopefully).

I am also writting scripts to collect all the results into one .csv
file, and plot it using Gnuplot in some user-friendly way.
Yours,
Peter
