Hello!
How to get aggregate values in log (_bw,_lat,_iops) files?
I use job with:
> group_reporting=1
> disable_lat=0
> disable_clat=0
> disable_slat=0
> numjobs=4
> per_job_logs=0
After benchmarking I�ve got output (normal) with aggregate (for all 4 jobs):
read : io=148620MB, bw=253474KB/s, iops=247, runt=600404msec
But in logs there are stats only about one job, job_bw.log:

May be I should multiply values in second column by 4? :)
Bye.

Look further down, the log will have each of the jobs following each
other. They are not summed for you, you have to do that.

Sorry, that’s my mistake, and I should be more carefull in further.
I wrote simple shell script to get average values, but it too slow for huge log files.
