dtrace discuss - Oct 2007 - List of DTrace probes/provides in libc ?

Hi!

----

Is there anywhere a list of DTrace probes/provides which are supported
by libc ?

Bye,

Hi Roland,

As with any other user-land library, DTrace can dynamically instrument
libc down to individual instructions via the ''pid'' provider.

For example, to see a list of which function entry points can be
instrumented in libc of pid 1234:

#dtrace -l -n pid1234:libc::entry

Let me know if you had something else in mind.

Erm.. only the list provided by the dtrace(1M) command itself:

# dtrace -n *$$:libc::,pid$$:libc:: -l

On my system there were about 350,000 probes. Currently libc only has the
plockstat USDT provider and, of course, may be instrumented by the pid
provider.
