NAME

6       profile - DTrace profile interrupt provider
7

DESCRIPTION

9       The profile driver is a DTrace dynamic tracing provider that adds time-
10       based interrupt event sources that can be used as DTrace probes.
11
12
13       Each profile event source is a time-based interrupt firing every fixed,
14       specified time interval. You can use these probes to sample some aspect
15       of system state every unit time and the samples can  then  be  used  to
16       infer  system  behavior.  If the sampling rate is high, or the sampling
17       time is long, an accurate inference is possible. By  using  the  DTrace
18       facility  to  bind arbitrary actions to probes, you can use the profile
19       provider to sample practically anything in the system. For example, you
20       could  sample  the  state  of the current thread, the CPU state, or the
21       current machine instruction each time a probe fires.

24       The profile driver is not a public interface and you access the instru‐
25       mentation offered by this provider through DTrace. Refer to the Solaris
26       Dynamic Tracing Guide for a description of the public documented inter‐
27       faces  available  for the DTrace facility and the probes offered by the
28       profile provider.
