Node.js profiling: Why does dtrace fail on Mac OS X Yosemite?

Question

Node.js

Trying to profile Node.js with DTrace on Mac OS X 10.10 Yosemite:

sudo dtrace -n 'profile-97/execname == "node" && arg1/{ @[jstack(150, 8000)] = count(); } tick-60s { exit(0); }' &> /tmp/dtrace.out

As a result, I get a bunch of errors: pastebin.com/NjbR2zug
Errors look like this:

dtrace: error on enabled probe ID 1 (ID 28: profile:::profile-97): invalid address (0x5) in action #2

Tried versions of Node.js installed with both Brew and NVM - same result.
What can be done about it?

Answer 1

Because OS X doesn't support jstack()dtrace in scripts. But it works on FreeBSD, SmartOS and you can still get an analogue on linux: www.brendangregg.com/FlameGraphs/cpuflamegraphs.html
