Thanks. :-) I'm a little surprised. You seemed pretty
dedicated to a per-process tool.
I was, but then I read your e-mail and became convinced that the
first patch that would be submitted against procstat(1) would be
a "-a" patch. :-)
Yep, would've happened. Now the first patch submitted will be a "-
w interval" patch... :-)
I couldn't resist implementing a crude interval arg just for kicks.
Here's the output of find(1) every second. This is so cool:
Very neat :-). If you like this, you'll love DTrace, which allows
you to do all sorts of things along these lines. I'll add a -w
mode, but be aware that if you want to do the below, what you really
want is DTrace :-), which allows you do do things like sample kernel
stack traces on the clock timer, based on function invocations, etc,
so you can do things like say "sample all the paths to a particular
kernel function". Now that John is updating DTrace again, I hope
that we'll be seeing it in the 8-CURRENT source RSN.

Sorry, just a bit off topic
Have the licensing issues been resolved with regards to DTrace? This
is a feature I was looking forward to in 7.0-RELEASE but it had been
delayed because of the licensing.
