Performance reporting issues.

[Waldher, Travis R]

I'm having an odd issue where SAR is reporting wildly different stats than what the system is doing.

I'm not sure where sa is pulling it's numbers from but I definitely don't and haven't had the CPUs running 36% for users and 63% for system for a long time.  It's more likely the system had been idle.

Any ideas?

$ sar -H -t -u -f /var/log/sa/sa16
