True, but managers only see graphs, two have the same
values, one doesn't....
I like Hobbit, and I want to keep it out here, so
justification wise, I'd like to make it look the
same.
I did a quick look at cpu, the load average is low,
but the high cpu utilization is coming from to much
iowait time because they are writing to NFS shares.
How does Hobbit get CPU utilization? Does it compare idle, user, kernel, iowait, swap?
(Say from Top)
So for example, utilization might be 100 - idle time.
and take samplings from idle time?
Thanks ... James

Subject: Re: [hobbit] CPU Utilization Not Correct or Averaging
If the other tools are using their own functions to get the utilization, it could show much different values than the operating system provided features that Hobbit typically uses. The sampling interval will also make a big difference. It's best to compare apples to apples (as much as you can).

I've had questions about CPU Utilization, The charts
don't seem to correlate with the other two monitoring
tools. As an example, The other tools show CPU
Utilization at 80% during a couple hours at night,
and Hobbit shows 26% Utilization.
Both the other Tools show 80% utilization during those
hours, but Hobbit doesn't.
I looked into this once before, and I know it depends on
how the data sampling is being done.
Any ideas on this would be helpful.
Thanks.James
