:Introduced: 8.2606.0

Description
-----------
The path to the named pipe (FIFO) to be monitored. This must be an absolute path.
The FIFO must exist on the filesystem before Rsyslog starts; `imfifo` will not attempt to create it.
If the file does not exist or is not a FIFO, an error will be reported at startup and the input instance will not be activated.

Input usage
-----------
.. _param-imfifo-input-file:
.. _imfifo.parameter.input.file-usage:

.. code-block:: rsyslog

   input(type="imfifo"
         file="/var/log/myfifo"
         tag="fifo-logs:")
