Since yesterday the vmstat command is displaying the cpu idle time at 100%At each time interval. It never changes. Not sure what it means other than it Quit calculating that stat. And I'm curious why. Using sar I can display a correctCpu idle percent, but vmstat does not. Any ideas why or suggestion to resolve.I was thinking a reboot might cure it, but it's a guess. Server has been up 83 days. We are running HP-UX B.11.11
We use vmstat constantly on all our HP-UX servers and we have never had a problem with it reporting. What make you think its wrong? Can you show some examples
We use 11.11 or 11.23.
And we hardly ever reboot.
Here is a vmstat output and following is sar output on the same server.
