fio terse输出详解

fio, the flexible IO tester, is a very useful tool for benchmarking IO performance. It has an option to produce minimal output, which is very useful when gathering data for later processing, e.g. graphing. The man page for fio describes the output format, but does not number the fields. This means that when extracting fields, one must count the fields in the man page to find the correct index to extract.

This page provides a handy reference to the field indexes used in the output to hopefully save you some time and effort.
