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.
