NAME

       systrace - DTrace system call tracing provider

DESCRIPTION

       The  systrace driver implements the DTrace syscall dynamic tracing provider. The syscall provider performs dynamic instrumentation to offer
       probes that fire whenever a thread enters or returns from a kernel system call entry point.

       The systrace driver is not a public interface and you access the 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 syscall provider.
