Please note, the individual CPU
time and combination is not making any sense.* That is from today.*
Let’s go back to where it was working on October 19th.

I’m still not sure how it
is figuring an average or whatever it is figuring for “ALL”, but it
appears to at least be more accurate up until 0500.


*


Sysstat version sysstat-5.0.5-1


*


Anyone have any advice?

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?
