On iostat -x
 

Did anyone use iostat -x?

I have one question on this command. When I type iostat directly, the screen will show

avg-cpu: %user %nice %sys %iowait %idle
4.05 0.00 15.56 0.02 80.37

Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn

sda10 12.36 15.39 96.03 642118854 4006083874

But when I use iostat -x, only sda is shown

avg-cpu: %user %nice %sys %iowait %idle

Could anyone help me on this and tell me why? Thanks a lot.

I know this is a bit old, but I found it in the zero replies...

What kernel are you running?
