system.cpu.util on solaris

[tdomhan]

hi folks,
I have a Solaris 10 machine here which I would like to monitor.
I'm especially interessed in the CPU usage. I added an item system.cpu.util, which works. It should show the cpu usage in percent shouldn't it?
well it shows something between 70-90% cpu usage.
though mpstat says something like this:

CPU minf mjf xcal  intr ithr  csw icsw migr smtx  srw syscl  usr sys  wt idl
  0    1   0    0   287   91  153    3    0    7    0  1077    5   1   0  94

so the machine idles 94% of the time, doesn't it?

and in prstat the only process consuming cpu is mysql with around 5%.

can somebody explain me that divergence?

edit: I'm using the newest 1.6 sources for both agent and server.

ok strange thing, if I do something CPU heavy the graph drops to the ground, what would be around 1%....
If I explicitly change the type to user the values seem fine.

is this a bug, or indented as the manual says "user" is the default?
