Top Forums UNIX for Dummies Questions & Answers Is total CPU usage for sar %user+%system+%iowait? Post 302616679 by Scrutinizer on Sunday 1st of April 2012 07:54:19 AM

It is a "single-CPU vmware machine", I presume OP means a virtual machine. In the 3rd column it says, all CPU, so I think it would not matter if there were more vCPUs.

There is a %idle column, but apparently there has not been an idle period without I/O activity. The three columns on the left are busy time, the three on the right are idle time..

So I think it is like this:
TOTAL USER = %user + %nice
TOTAL CPU = %user + %nice + %system
TOTAL IDLE = %iowait + %steal + %idle
