where can i get the variable tree for kvm & kstat

Hi all,
I am working on the symbEL to get some specific value from the kernel recently. But I am not sure whether kvm and kstat have such specific value. i checked the examples included with the RICHPse but didn't get the answer. also the "kstat" seems not have any description.
Is there a variable list for kvm and kstat for kernel? and if it does, where can I download it?

Thanks in adv.

Just run kstat. Without args it prints everything.

but it seems that there is too few description. As a rookie like me, could not get much info from it.
