dtrace discuss - Mar 2009 - trace static function

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 traced.

There''s a way with the dtrace pid-provider to trace static function?

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).
