| 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 |
