NAME
     sdt - DTrace statically defined tracing provider

DESCRIPTION
     The sdt driver is a DTrace  dynamic  tracing  provider  that
     performs dynamic instrumentation at statically-defined loca-
     tions 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.
