Hi All,
I have a feature request. One of the things that is missing (in my
opinion) from the json output is the actual fio job configuration.
In the current state it outputs a json file with all the output from the
jobs run. One addition that would make it very helpful for parsing and
comparing data (especially historical data or data run by another
engineer) is to have the actual job file as a key inside the json
output. This could be something as simple as just putting the parsed
command line argument in
fio --ioengine=libaio --buffered=0 --norandommap --log_avg_msec=10000 --
direct=1 --ba=4k --ramp_time=0 --runtime=1800 --time_based --
filename=/dev/sdg --name=8K_RR_QD1 --name=8K_RR_QD1 --bs=8k --
rw=randread --iodepth=1 --write_iops_log=./8K_RR_qd1_
Or even better would be a dictionary inside the json with every
configuration parameter verbosely printed (like the below "jobinfo")
{
"fio version" : "fio-2.1.10",
"jobs" : [
{
"jobname" : "8K_Random_Read",
"jobinfo" :{
"ioengine" : "libaio"
"buffered" : 0
"norandommap" : 1
"log_avg_msec" : 10000
"direct" : 1
"ba" : 4k
"ramp_time" : 0
"runtime" :1800
"time_based" : 1
"filename" : "/dev/sdc"
"name" : "8K_Random_Read"
"bs" : "8K"
"rw" : "randread"
"iodepth" : 1
}
"groupid" : 0,
"error" : 0,
"read" : {
I understand it would add size to the output but I think it would really
help.
That would be very useful, you're not the first to bring it up. I'll be
happy to take patches to add this feature.
