Chapter 14


This chapter describes the privileges that system administrators can use to grant access to DTrace to particular users or processes. DTrace enables visibility into all aspects of the system including user-level functions, system calls, kernel functions, and more. It allows for powerful actions some of which can modify a program's state. Just as it would be inappropriate to allow a user access to another user's private files, a system administrator should not grant every user full access to all the facilities that DTrace offers. By default, only the super-user can use DTrace. The Least Privilege facility can be used to allow other users controlled use of DTrace.
