I am trying to get multiple output formats working with fio and I am getting a core dump fio: diskutil.c:710: show_disk_util: Assertion `parent' failed. Aborted (core dumped) I am utilizing format from commit a666cab8ed3d2a2fa782be345425a2e88734a007 Author: Jens Axboe <axboe@xxxxxx> Date: Tue Oct 27 13:45:21 2015 +0900 Enable the use of multiple output formats You can now do ./fio --output-format=normal,json jobfile.fio and get both types of output. Signed-off-by: Jens Axboe <axboe@xxxxxx> fio -v fio-2.6-10-g820b fio --ioengine=libaio --buffered=0 --direct=1 --norandommap --name=test --filename=/dev/sdb --iodepth=32 --ba=4k --rw=randrw --rwmixwrite=65 -- bs=8K --numjobs=1 --runtime=10 --ramp_time=0 --time_based --output- format=terse,json I have also tried --format=normal,json and I get the same issue --output-format=normal,terse Works just fine but I really would like to have json output along with terse. Is there a workaround to get both terse and json (or json+)?
