If anyone interested - i was able to compile dtrace support in mysql-server55 port. During this i found a bug in dtrace/bsd - if it is running more then 1 time on the same object (this is the case for mysqld) then object is broken. I was able to do workaround (with preserving original object and then copying it) and then everything compiled and started correctly. This is an example: bsd# ./work/mysql-5.5.14/support-files/dtrace/query-time.d dtrace: buffer size lowered to 2m Who Database Query Time(ms) root@localhost mysql select sleep(1) from user limit 1 1000 root@localhost mysql select * from user limit 1 0 I will try to cleanup my patches (its currently very dirty hacks) and submit them to the mysql bugtracker (and port). Feel free to contact me if you want to test this (or to fix dtrace/obects bug).
