Hey, I am wondering how can I enable dtrace probes to ruby
However:
r...@opensolaris:~# dtrace -l | grep -i ruby | wc -l

(just to confirm r...@opensolaris:~# dtrace -l | grep -i postgres |
wc -l
55
)
dtrace -l by itself will only show kernel probes. I doubt there are
any probes in
the operating system for ruby or postgres. You might try looking at
http://ruby-dtrace.rubyforge.org/ for an example of using dtrace with
ruby.
(Or, do what I did... search the net for "ruby dtrace probes".
dtrace -l will actually show all currently registered probes including
user land USDT probes.
However an instance of an application with USDT probes has to be
running in order to list it.
Thanks for the correction Robert. I realized that about 5 minutes after
I sent my email,
but wasn't sure about terminology since I did not enable the user land
probes, only listed them.
And of course, the probes are handled in the kernel, so they have to be
there. "Registered" works
fine.
