DTrace Data Recording Actions

The data recording actions comprise the core DTrace actions. Each of these actions records data to the principal buffer by default, but each action may also be used to record data to speculative buffers. For more information about the principal buffer, see DTrace Buffers and Buffering. For more information about speculative buffers, see Speculative Tracing in DTrace. The descriptions in this section refer only to the directed buffer, indicating that data is recorded either to the principal buffer or to a speculative buffer if the action follows a speculate.
