Hi,

I have been trying to run xenmon in its logging mode to collect statistics for offline analysis. However  I notice that at an interval of 100 ms or so the overhead imposed by dom0 is quite high , with upto 40% of CPU utilization.

Are there ways I can drastically reduce this overhead ? I read somwhere about event overhead, using event masks and python overhead,  but am not really sure how to use this information to reduce the overhead.

Any help is greatly appreciated !

thanks,
Ashish
