Hi
If I list all the providers I see a list for apache like below:
apache3156
apache3164
apache3165
apache3167
apache3168
apache3509
apache7363
apache7364
apache7365
apache7366
apache7367
Why do I see so many and what are their differences.
Best Regards Paul

Hi Paul,
Apache has USDT probes
(http://wikis.sun.com/display/DTrace/Statically+Defined+Tracing+for+User+Applications)
defined in it. These are per-process and are unique to a running
instance of Apache process. That explains why you
see probes of the form apachepid:::.
thanks,
Krishnan

Thanks Nico. Since arg1 is a pointer to a struct in userland, can I use
ptr = *(uint32_t *)copyin(arg1,
I am getting a 64bit address for char pointer for a 32 bit process. I don't
know if I am getting the casting correct.

typedef struct door_arg {
char *data_ptr; /* Argument/result buf ptr*/

Thank you Michael and Nico. I will post my results after the test.
Much appreciated.

have been playing with dtrace for the past week and besides some beginner
errors I'm doing basically fine (thanks again Adam).
I just switched to a different system, and all of a sudden it takes about 15
seconds for the dtrace script to start and then an other 6 seconds to terminate.
