Your best bet is to look into xentrace & xenalyze, and the trace or TRACE calls found in xen.git/xen/common/sched/credit[2].c. It looks like you can get the info you want for credit2, but not for credit1 unless you add some trace points in. You can find a video introduction to Xen tracing here: https://vimeo.com/33655967 It's a bit old but that system hasn't changed much. -George > > On Thu, Jan 6, 2022 at 2:32 PM George Dunlap <dunl...@umich.edu> wrote: > >> >> >> On Wed, Jan 5, 2022 at 2:45 PM amir masoud noohi <highlim...@gmail.com> >> wrote: >> >>> Hi Everyone, >>> >>> Today I'm looking for capturing vCPU credit for both credit1 and >>> credit2. >>> How can I do that? >>> >> >> Can you explain what you mean by "capture vCPU credit"?
