Hello,
I have used the following simple dtrace script to debug a problem with
vmstat:
#!/usr/sbin/dtrace -s
#pragma D option flowindent
pid$1:a.out:::entry
{
self-start = 1;
ustack(15);
}
pid$1:a.out::return
/self-start/
{
ustack(15);
}
However I have noticed that static function are not
I succeeded in placing USDT probes in a main program, but when I tried to do
the same thing in a shared library I got the following link errors:
Undefined first referenced
symbol in file
__dtrace_toposnap___topo__snap__release__entry
I've tested the same code with opensolaris 2008.11 with svn101b and
php_dtrace_execute_internal works well, maybe a regression ?

Hi Michael,
Crossposting to webstack-discuss. That list covers the group of
packages which cover web functionality, like PHP.

Hi,
I test the dtrace plugin for php and there is only php_dtrace_execute that
seems to work,
Oh, very impressive !
Thanks, I'll wait for the next update :)

Hey Andrea,
The pid provider can trace anything that's in either the dynsym or
symtab. If
the symbol isn't in one of those, you're out of luck. Make sure you're
not
stripping the binary, and use nm(1) to check for the symbol (-D for
the dynsym).
