I want to go a lot deeper with my tracing of MySQL and to do so I want to look into MySQL Thread Descriptors (class THD). Inside is a great bulk of information utilized by a great many of the core functions within MySQL... I really want to get in there. So far I''ve had no luck though. It''s a C++ class, and I''m afraid that I''m approaching it like a C struct,

everyone, Just out of curiosity, I did a dtrace -n ''syscall:::entry { @num[execname, probefunc] = count(); }'' and looked at the entries produced by ''rm''. I see everything that rm did, *except* the unlinkat - which is unfortunate because I want to trace which processes have deleted which files. So - does dtrace contain unlinkat as a probe for a system call?
