Hi all, I'm a newbie in dtrace, and I following this tutorial from Oracle: http://docs.oracle.com/cd/E19205-01/820-4221/ to learn dtrace. In the example of test.c and ufunc.d, I expected output like this: % dtrace -s ufunc.d -c ./a.out a.out dtrace: script 'ufunc.d' matched 5 probes dtrace: pid 27210 has exited inet_makeaddr 1 foo1 1 foo 1 main 1 __fsr 1 But I got this instead: # dtrace -s ufunc.d -c ./a.out a.out dtrace: script 'ufunc.d' matched 5 probes dtrace: pid 86498 has exited # My system info: root@home:/home/spin6lock/test # dtrace -V dtrace: Sun D 1.7 root@home:/home/spin6lock/test # uname -a FreeBSD 9.1-RELEASE FreeBSD 9.1-RELEASE #1: Mon Oct 28 20:52:03 CST 2013 root@xiangling:/usr/obj/usr/src/sys/DTRACE amd64 Any clues? Thanks in advanced. Cheers, spin6lock
