Well, the instrumentation "on demand" aspect is half of the truth.
A probe inserted through kprobes impacts performance more than static
instrumentation.
True, but given that there are going to be a number of things you might
want to instrument at some point, and that at any given time you might
only be interested in a few of those, it likely will be better overall
to spend some more time only on the few than less time on the many.
Im sure there will be more discussions to sort out which data should be
retrieved through which kind of instrumentation, and to find the right mix.
But I won't dare speculating about the outcome. I am just tossing another
request for data into the discussion (important, in my eyes), along with a
method for retrieving such data (less important, in my eyes).
