Too late, I already put v2 patch through the process. Some good, some bad. The good is that no more dropped entries appear in the middle! So for the iops and bw logs, I get results such as: 999, 293814, 0, 0 2000, 354857, 0, 0 3000, 383081, 0, 0 ... 57000, 321946, 0, 0 58000, 321566, 0, 0 59000, 321596, 0, 0 The first sample is slightly off, but well within a reasonable tolerance. The last sample is always missing (runtime=60s). The bad is that the slat/clat/lat log is not doing averages any more, such as log_avg_msec=1000, but it's logging every value. # fio --name=test_job --ioengine=libaio --direct=1 --rw=randread --iodepth=256 --size=100% --numjobs=4 --bs=4k --filename=/dev/nvme0n1 --group_reporting --write_bw_log=test_job --write_iops_log=test_job --write_lat_log=test_job --log_avg_msec=1000 --disable_lat=0 --disable_clat=0 --disable_slat=0 --runtime=60s --time_based --output=test_job
OK, I guess it's not perfect! I'll tackle that one. -- Jens Axboe -- 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
