DESCRIPTION
The sdt driver is a DTrace dynamic tracing provider that performs
dynamic instrumentation at statically-defined locations in the Solaris
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 Solaris Dynamic
Tracing Guide for a description of the public documented interfaces
available for the DTrace facility and the probes offered by the sdt
provider.
