NAME

6       fasttrap - DTrace user instruction tracing provider
7

DESCRIPTION

9       The  fasttrap driver is a DTrace dynamic tracing provider that performs
10       dynamic instrumentation of arbitrary instructions in Solaris processes.
11       The fasttrap driver implements the DTrace fasttrap and pid providers.

13
14       The fasttrap driver is not a public interface and you access instrumen‐
15       tation offered by this provider through DTrace. Refer  to  the  Solaris
16       Dynamic Tracing Guide for a description of the public documented inter‐
17       faces available for the DTrace facility and the probes offered  by  the
18       fasttrap provider.

SPARC ONLY

21       The  fasttrap  provider  provides a DTrace probe that fires each time a
22       user process executes an instruction. The pid provider allows  for  the
23       dynamic  creation  of  DTrace probes corresponding to instruction loca‐
24       tions inside any user process specified  using  a  process  ID  and  an
25       instruction  address  or  symbol  name. Together these providers permit
26       DTrace users to perform instrumentation of Solaris user  processes  and
27       to  trace  the interactions between processes and the operating system.
28       See the chapter entitled "User Process Tracing"  in the Solaris Dynamic
29       Tracing  Guide for information on how to use these providers to instru‐
30       ment processes.
