The simplest way of a basic test should be:

- Put into your kernel.conf:
   options         KDTRACE_FRAME # could be for amd64 only
   options         KDTRACE_HOOKS
   options         DDB_CTF # could be optional

- make buildworld  WITH_CTF=1 && make buildkernel WITH_CTF=1

- Put into your loader.conf:
   dtraceall_load="YES"

After reboot check:
dtrace -l

If you see lots of fbt and sdt (esp. the nfs ones) providers all should be 
prepared and fine.
