fio output parameter

fio output parameter

[Jeff Furlong]

Hi All,
When in command line mode, the output parameter dumps the output to a file.  When in job mode, the output parameter cannot be used, so all output goes to stdout.  Can the output parameter be used with job files?  Consider below:

# fio -version
fio-2.19-59-gf52e9

#fio --name=test_job --ioengine=libaio --direct=1 --rw=randread --iodepth=1 --size=100% --numjobs=1 --bs=4k --filename=/dev/nvme0n1 --runtime=10s --time_based --output=test_job

#cat text.txt
[test_job]
ioengine=libaio
direct=1
rw=randread
iodepth=1
size=100%
numjobs=1
bs=4k
filename=/dev/nvme0n1
runtime=10s
time_based
output=test_job

# fio test.txt
Bad option <output=test_job>


Regards,
Jeff

Hi,

You can use the following:

fio --output kuku.log test.txt

and remove output from the job file

Thanks.  Using --output on the command line will work for my simple example.  However, if I make two jobs in one file, then the --output parameter forces all output into one file.

[test_job]
ioengine=libaio
direct=1
rw=randread
iodepth=1
size=100%
numjobs=1
bs=4k
filename=/dev/nvme0n1
runtime=10s
time_based
output=test_job
[test_job2]
ioengine=libaio
direct=1
rw=randread
iodepth=2
size=100%
numjobs=1
bs=4k
filename=/dev/nvme0n1
runtime=10s
time_based
output=test_job2

Maybe it's best to make one job file per fio job.

Regards,
Jeff
