James, I suspect that the CPU utilization numbers come from "vmstat" output. There should be a section in the client data labeled [vmstat] and the numbers that are graphed are listed in the far right hand columns. I guess the [iostatcpu] section could be used as well -- that adds the "wt" column to "us, sy, and id".
On one of my Solaris systems, I have something that looks like this:
[vmstat] kthr memory page disk faults cpu r b w swap free re mf pi po fr de sr s0 s1 s3 -- in sy cs us sy id 0 0 0 22683696 6595936 41 257 1 0 0 0 0 3 2 0 0 573 1703 631 1 2 97 0 0 0 22077552 5982992 38 240 0 0 0 0 0 3 3 0 0 608 3125 839 2 2 97 [iostatcpu] cpu us sy wt id 1 2 0 97 2 2 0 97
It is possible that your vmstat output is not formatted the way that Hobbit expects (extra columns?) Your graph looks different -- usually the CPU utilization graph for Solaris is a stacked area chart, not a line graph.
Others may be able to chime in with more things to consider. Good luck!

The Operating System is Solaris.
The graph definitions have not been changed.
What should I look for with the client data?
I'm not familiar with rrd.
Although if I look at all the clients overall, I see
the same thing, the averaging of CPU Utilization
is a flat-line on everything, even during peak loads.

What OS, version, etc. And did you look into your client datafile to see what is in there? And has anyone monkeyed with the graph definitions?
You have the smoking gun, but that's about all we have to workon...

I could not send all the graphs in the same email.
This is the same system with the other two graphs,
but this is a different monitoring tool another group
uses. It shows CPU Utilization at 100% which is
correct with a load of 120+. However, Hobbit, showed
a flatline at 13%..
I'm seeing this across the board on all the systems,
and the tool below is being used by the other group
showing the discrepancies. Any suggestions?
Thanks....James

I really need some help on the CPU Utilization graphs.
They just don't look correct.
As an example, CPU Load on this box went to 120+,
for an hour, but the CPU Utilization Graph for the same
time period shows only 13% busy.
