Using the following dtrace command, I can see who''s calling what with lots of +/- numbers: dtrace -n ''fbt:ip:ip_output:entry{@dbtypes[((mblk_t *)arg1)->b_datap->db_type,caller] = count();}'' ...the output is what I want but not how I want to see it. What I''d rather see is the function names associated with caller and for db_type to be output in hex. Looking at the docs online for s10, http://developers.sun.com/solaris/articles/dtrac...

Hi i''m trying to write my first dtrace script apparently i bit off a bit more than i can chew, i want to track io over sockets, i found your socketsize.d that gave me how to track writes, but i''m at a loss how to track reads, frankly i don''t see how your write tracker works because it uses a probe in a function that only takes two arguments but you grab size of write
