Hi all, 

Now I use xentop to get disk statistical information.

For the red part, I need to change the size to MB or KB. 

Just now, I check the xentop code, xentop gets the related information from 
/sys/devices/vbd-29-51713/statistics/rd_sect or /sys/devices/vbd-29-51713/statistics/wr_sect files.

I do not know how to change these number to MB or KB. 

Does anybody know how to do that?
