vmstat strange output

Dilip Raj — Fri, 31 Aug 2001 15:44:40 GMT

Hi, I just did vmstat 5 5 on my machine, and I am getting strange output.
# model
9000/887/G70/H70
# vmstat 5 5

My id column in CPU sections shows negative values?
cpu
us sy id
24 5 71
102 2 -5
103 2 -5

Any Idea?

Dilip

Hi
The "us" column is also strange as it is over 100% !

What is top showing or sar -u?

Dilip,

Thing to notice here is the total of us sy and id remained around 100%.

I think due to high %USR utilization, the averaging might be getting inapproximated within the vmstat program itself.

What is the value for pswtch/s in your sar -w output ?
