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
