Hi Jens,
it seems that the command line options "write_iops_log" and "write_bw_log" don't work as they are described in the man page:
"If no filename is given with this option, the default filename of "jobname_type.log" is used."
Unfortunately the files/filenames are not created automatically by fio:
# fio --name=test --direct=1 --refill_buffers --filesize=1G --bs=8k --rw=randread --ioengine=libaio --runtime=60 --write_iops_log --write_bw_log
[...]
# ls
lost+found test.1.0 --write_bw_log_iops.log
If I specify the filenames everything is fine:
# rm ./--write_bw_log_iops.log
# fio --name=test --direct=1 --refill_buffers --filesize=1G --bs=8k --rw=randread --ioengine=libaio --runtime=60 --write_iops_log=rr-iops --write_bw_log=rr-bw
[...]
# ls
lost+found rr-bw_bw.log rr-iops_iops.log test.1.0
I am using fio version fio-2.1.2-13-g3e10.
Best regards, Georg

Don't think there's an easy way to fix this, outside of requiring some
name being set. Arguably that should probably be the way that it functions.
