incorrect value on vmstat

Hello,

I have a system with eight CPUs and I'm wondering how are the values of the cpu columns be calculated. Here is my output.

psrv3.lewis:/mes3/lewis> vmstat 3
procs memory page faults cpu
r b w avm free re at pi po fr de sr in sy cs us sy id
8 0 0 473332 1974293 0 0 0 0 0 0 0 0 58 1 100 0 100
8 0 0 473332 1974175 29 3 1 0 0 0 0 6539 5815 1106 100 0 100
8 0 0 471795 1974462 16 0 0 0 0 0 0 6158 5322 1078 100 0 100
8 0 0 471795 1974457 8 0 0 0 0 0 0 6912 5314 1130 100 0 100

Here is another output for each cpu.

hpsrv3.lewis:/mes3/lewis> vmstat -n 3

Can any one tell me how does vmstat get 100 on column us and id? Many thanks.

Hi!

Since you seem to get even values >100 I would suggest you install PHCO_25979 (assuming you are on 11.11).

The vmstat(1) derives the metrics from pstat() system call. Should be the same as for top(1).
