Hi all,

If I want to measure the Dom0 CPU utilization, which is a more
accurate way among the following 3 options?
1. Running profiling program like "sar" in domain 0.
2. Running Xentop in domain 0
3. Running Xenmon.py in domain 0
By running these 3 different program, the results have certain
differences. So I am confused here which to use.Thank you in advance.

Lei
