Hi The sar and vmstat data seem to be very misleading while running inside a guest or even in dom0. The numbers just don't add up. For example, I see that when I run an app natively (linux) I see 1000 interrupts/sec, while running the same app inside a guest and collecting sar either in dom0 or inside the guest, the number of interrupts is about 40-60. Has anyone gotten these tools to work? Would appreciate some help to get these tools working Thanks - Padma _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
