I'm calling fio v2.0.8 from the command line in linux, and I wanted to set the averaging time for the log data to 200msec. Here is the command line I used: fio --name=SeqWrite --readwrite=write --bs=128K --iodepth=1 --ioengine=libaio --direct=1 --invalidate=1 --output=/tmp/fio_output --write_bw_log=bw_seq128K --write_lat_log=lat_seq128K --write_iops_log=iops_seq128K --log_avg_msec=200 --randrepeat=0 --norandommap --offset=0 --size=128035676160 --filename=/dev/sdaa But when I examined the logs that fio produced, the BW and the IOPS logs had the default 500msec resolution. But the latency logs had my requested 200msec resolution. Is this an fio bug, or did I misunderstand something?
