omstdout: stdout output module (testbench tool)

Module Name:    omstdout

Author:Rainer Gerhards <>

Available Since: 4.1.6


This module writes any messages that are passed to it to stdout. It was developed for the rsyslog test suite. However, there may (limited) other uses exists. Please not that we do not put too much effort into the quality of this module as we do not expect it to be used in real deployments. If you do, please drop us a note so that we can enhance its priority!

Configuration Directives:

  • $ActionOMStdoutArrayInterface [on|**off** This setting instructs omstdout to use the alternate array based method of parameter passing. If used, the values will be output with commas between the values but no other padding bytes. This is a test aid for the alternate calling interface.
  • $ActionOMStdoutEnsureLFEnding [on|off Makes sure that each message is written with a terminating LF. This is needed for the automatted tests. If the message contains a trailing LF, none is added.

Caveats/Known Bugs:

Currently none known.
