I meant what are you using gluster for? VM workload or image/video file

1) We use glusterfs for general purpose, no limit to image/video file
creation or small files etc.
Okay, this is good. What is the cluster size?
Is it replica 3 or replica 2 or arbiter or is it EC volume?
Please don't mind me asking so many details. I am delighted to see you guys active in the community because I have seen Xiubo Li's work on tcmu-runner who is also from chinamobile and his work is pretty good :-).
2) We just want a low performance affect way to calculate each brick's iops/bandwidth for the upper layer management app. BTW, is there any other way to get iops/bandwith for each brick besides profile?
At the moment we have these stats using profile commands. As per Facebook patches they enable json capture of io-stats on their volumes and measure these. They have it enabled always. If that is not enough for you, then we should probably look at enhancing things. Do send patches if you think something would make things better :-).
