Development
Huge thanks to BrendanGregg for so much of the dtrace magic.
dtrace the kernel while running a command:
dtrace -x stackframes=100 -n 'profile-997 /arg0/ { @[stack()] = count(); } tick-60s { exit(0); }' -o out.stacks
it will run for 60 seconds.
Convert it to a flamegraph
./stackcollapse.pl out.stacks > out.folded ./flamegraph.pl out.folded > out.svg
This is ```rsync -ar /usr/ /BOOM/deletea/``` running;
