I am not sure, if i got your requirement correctly.
If you need to have the file count and directory count of each brick
individually (without aggregation), you could get that by a getxattr of
trusted.glusterfs.quota.size on the brick.
The size xattr value can be interpreted as follows:
getfattr -d -m. -e hex ' <path >
size: first 16 bytes
filecount: Next 16 bytes
dircount: Last 16 bytes
