I found following as the output of diskstats:

Field 1 -- # of reads issued
Field 2 -- # of reads merged,
Field 3 -- # of sectors read
Field 4 -- # of milliseconds spent reading
Field 5 -- # of writes completed
field 6 -- # of writes merged
Field 7 -- # of sectors written
Field 8 -- # of milliseconds spent writing
Field 9 -- # of I/Os currently in progress
Field 10 -- # of milliseconds spent doing I/Os
Field 11 -- weighted # of milliseconds spent doing I/Os

But I don't know yet what are these names:
ram0-15, loop0-7, nbd0-15, mtdblock0-3 and mmcblk
Yes maybe I know what is RAM or MMCBLK but what about the others ?
