On a further note, if you're willing to work on a complete libkstat JNI
interface, this could be extremely beneficial to Solaris. We're just
starting to really elevate Java to a first class participant in systemic
observability within Solaris. We have the DTrace JNI nearly finished,
and we're developing a SMF JNI interface as well. A kstat interface
would fill a very useful gap in this portfolio.
I can imagine a tool which presents kstats in a heirachial manner on
regular intervals, and the user can click on one the kstats and transfer
to a DTrace view where we can see the kstats on a per-process basis.
This would obviously only work for those kstats covered by the vminfo
and sysinfo providers, but would be _incredibly_ cool, since it answers
the first two questions any administrator tendds to have:
"What is happening to my system?"
"Who is doing that to my system?"
Assuming that the problem is due to a particular process, of course.
But you get the picture.
