8 fasttrap \- DTrace user instruction tracing provider
11 The \fBfasttrap\fR driver is a DTrace dynamic tracing provider that performs
12 dynamic instrumentation of arbitrary instructions in illumos processes. The
13 \fBfasttrap\fR driver implements the DTrace \fBfasttrap\fR and \fBpid\fR
17 The \fBfasttrap\fR driver is not a public interface and you access
18 instrumentation offered by this provider through DTrace. Refer to the
19 \fIDynamic Tracing Guide\fR for a description of the public documented
20 interfaces available for the DTrace facility and the probes offered by the
21 \fBfasttrap\fR provider.
24 The \fBfasttrap\fR provider provides a DTrace probe that fires each time a user
25 process executes an instruction. The \fBpid\fR provider allows for the dynamic
26 creation of DTrace probes corresponding to instruction locations inside any
27 user process specified using a process ID and an instruction address or symbol
28 name. Together these providers permit DTrace users to perform instrumentation
29 of user processes and to trace the interactions between processes and
30 the operating system. See the chapter entitled "User Process Tracing" in the
31 \fIDynamic Tracing Guide\fR for information on how to use these
32 providers to instrument processes.
