# IOMeter defines the server loads as the following:
# iodepth=1                    Linear
# iodepth=4                    Very Light
# iodepth=8                    Light
# iodepth=64                    Moderate
# iodepth=256                    Heavy
iodepth=64

修改filename 及 size
其他參數視需要修改

以上存為 test.fio

執行fio test.fio

用shell 重複執行

#/bin/bash
rm /tmp/fio_test_log

while :
do
    fio test.fio -output=/tmp/iolog
    cat /tmp/iolog >> /tmp/fio_test_log
