I'm running many benchmarks and organize the output by using genfio to name both files and logs. But, there is always a but, it's impossible while taking a log file to understand in which setup fio ran to produce this log. So I'd like to add several things inside the log file: 1- the role of each column 2- an header that reports what was fio setting for this log Pro: - Taking a log file is enough to understand the performance inside Cons: - That would break the current format : I'm thinking about commenting thoses lines. Any ideas, comments ? Cheers,
