Hi, I was wondering how I can measure the load of the cpu in dom0. I tried it with dstat but this gave me a result that only one core is used and thats a bit strange. Afterwards I realized that it was because dstat triggers on the running processes and what happens in the VM is not in the running processes of dom0. So I guess this is the overhead of running xen on the dom0. I have this simple setup. Dom0 with a dual core cpu VM1 with 1vcpu and 128 mb ram VM2 with 2vcpu and 128 mb ram Ive installed apache2 on these VM and stress test these VM simultaneously with a sort of httperf test. In my VM I measure the load via dstat and see that the second VM uses his 2 cores. On my dom0 now, I want to see how this maps on the physical cpu load. So I want to know how this load on the VM is spread across the physical cpu. I dont really see how I can extract this from the xentop tool. I dont know if there is a way to see the load of the 2 cores in a simple and clean way. If it is possible provided in a csv file of something easy to put in a graph. I also tried the xenmon script in the xen-utils and this shows me the load of cpu0 or cpu1 but I dont see how to get them both without running xenmon twice. I also dont get yet what the numbers mean in xenmon. If I read the readme: cpu(tot) = Total time used over the measurement interval cpu(%) = Usage expressed in percentage cpu/ex = ???? So what I just want to have is some usefull data about the cpu load of dom0. Maybe there is a simple tool to achieve this? Or maybe someone can explain a bit more the cpu data which xenmon provides? Because I did not find that much other info about it.
