Hello,
I'm trying fio on solaris sparc and I'm having an strange issue : io_bytes, bw, iops, runtime values are 0 when json output is enabled but contains valid values when using text (or terse) output format.
I have tested on solaris x64 and everything is fine.
Output (text format) :

My profile file is :

I'm using fio-2.1.6 rebuilt with gcc 4.8.0 with the default configure script.
Thanks
