[Xen-devel] What is the standard procedure for CPU usage calculation for "Two" Core Dom0..?
Hi, I am using "XenAPI -1.0.6" ... I have "Dual Core" machine on which I am working..I am trying to fetch Dom-0 CPU utilization using XenAPI RPC "get_utilisation()"(class host cpu).... Since my machine is dual core this function is yielding me utilization of Core 1 & Core 2 separately(e.g Core ONE - 0.4241242424 & Core TWO - 0.3254842450)..I just want to calculate the overall CPU utilization in percentage for the Dom-0...What is the standard procedure in this case to calculate overall CPU utilization in percentage by considering above two CPU utilizations for each core ?

I think it''s wrong to implement the API to return the percentage. if return the actual usage, it should be better. see: http://lists.xensource.com/archives/html/xen-devel/2008-09/msg00069.html thanks, zhigang kushal waikar wrote:> Hi, > I am using "XenAPI -1.0.6" ...
