Thread-topic: Sar, iostat and vmstat
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
