Null (im_null)

This module does not generate any input, so basically it does nothing. Yet it can be useful for creating a dummy route, for testing purposes, or for Scheduled NXLog code execution. The im_null module accepts only the common module directives. See this example for usage.

To examine the supported platforms, see the list of installer packages in the Available Modules chapter.
