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 apache<pid>:::.
thanks,
Krishnan

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
