 Many thanks Fujar,
I will try your suggestion later.

But the xentop also read NETTX and NETRX from vif , why not from eth0
bridge in xen-3.4.1?

BTW, for DomU, xentop tell me the correct NW traffic value ( because vif is
generated at Dom0's side).

My old test program run well at xen-3.1.0.
I used it to monitor DomU and Dom0's CPU, NW loading at every time ( like
this way -> xentop -b -d 1). So I felt it's easier to find out DomU and
Dom0's
CPU loading's change trend when I put NW load at DomU.

xentop is very useful monitoring utility for me, if it gives some
harddisk load
monitoring, it would be more effective monitor utility.

Is there any another utility or xen API better than xentop that can monitor
CPU, NW, HDD loading/sec ?
