Requirements to run DTrace

1. dtrace framework should be installed; (check if /usr/sbin/dtrace exists)

2. the user should have the following rights: dtrace_proc, dtrace_user, dtrace_kernel

   To give a user a privilege on login, insert a line into the /etc/user_attr file of the form: user-name::::defaultpriv=basic,dtrace_proc,dtrace_user,dtrace_kernel

   or

   To give a running process an DTrace privilege, use the ppriv(1) command:

   ppriv -s A+privilege process-ID
