NAME


sdt - DTrace statically defined tracing provider

DESCRIPTION


The sdt driver is a DTrace dynamic tracing provider that performs dynamic
instrumentation at statically-defined locations in the kernel.


The sdt provider allows kernel developers to explicitly create probes at
formally designated locations in the operating system kernel and loadable
modules, allowing the implementor to consciously choose the points in
their code that are desired probe points, and to convey some semantic
knowledge about that point with the choice of probe name and a relevant
set of arguments.


The sdt driver is not a public interface and you access instrumentation
offered by this provider through DTrace. Refer to the Dynamic Tracing
Guide for a description of the public documented interfaces available for
the DTrace facility and the probes offered by the sdt provider.
