So the Chime Visualization Tool for DTrace is now available.
I'm itching to try this out, and to see how you can build bridges with kstat (by means of jkstat or something different).
Unfortunately there appears to be a network problem with my test machine. Or more specifically there's a problem somewhere in the path between where I'm sat and where it's at. I've managed to determine that the machine itself is fine, but doing any work on it is impossible. It being a holiday I don't expect it to be fixed for a day or two.
