NAME
tracem - STREAMS activity trace module
SYNOPSIS
tracem
DESCRIPTION
tracem reports on messages passing through active Streams. You can
insert instances of tracem at any point or points in one or more Streams.
Those instances then send copies of messages passing through them to
another instance of tracem designated as a reporting module.
Use (trconf(1)) to insert or remove tracing instances of tracem on a
Stream. The trconf utility also lists open Streams and the modules on
them, and configures tracem modules to report on specific kinds of
messages. The utility trmon(1) opens a Stream to /dev/nuls, pushes a
reporting instance of tracem onto that Stream, then prints (on standard
output) messages sent to the reporting instance by tracing instance(s).
