All, Can someone please confirm if my usage is correct as earlier the offset used to be logged by using the log_offset=1 in the files. I am using FIO3.5. fio --name=global --time_based --size=100% --direct=1 --norandommap --randrepeat=0 --buffered=0 --refill_buffers --name=job --ioengine=libaio --group_reporting --filename=/dev/nvme0n1 --numjobs=1 --iodepth=128 --bs=128k --rw=rw --rwmixread=70 --runtime=10800 --write_iops_log=wr.log -write_lat_log=wr.clat.log --log_avg_msec=1000 --log_offset=1 appreciate the support. Life is too short for silly things so invest your time in some productive outputs!! -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
