write_iops_log/write_bw_log command line parameter bug

["Georg Schönberger" <gschoenberger@thomas-krenn.com>]

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
