Subject: Re: fio terse output for WRITE not working.
Hi Steve,
I found terse/minimal output to be quite unstable and inconsistent in
fio. So, as suggested by Jens, I switched to json output
(--output-format=json). It seems to be more stable and is also quite
easy to parse.
Perhaps that's an option for you.
Vasily
I'll check out json. Thanks Vasily.
json is vastly superior - easy to parse by both humans and computers.
That said, the terse format should of course work. I ran a quick test
just now, and I don't see anything wrong?
See my original posting on this. The write terse output only has zeros
for the over bandwidth in the first few fields of the record. read works
fine for me though.
Yes, I'm saying I don't see this happening. This is my quickie test case:
