The syslog-ng 3.0 Administrator Guide

The pipe() driver sends messages to a named pipe like /dev/xconsole.

The pipe driver has a single required parameter, specifying the filename of the pipe to open. The filename can include macros. For the list of available optional parameters, see Section 8.2.3, “pipe()”.

Declaration:
                pipe(filename);

	Warning
	As of syslog-ng Open Source Edition 3.0.2, pipes are created automatically. In earlier versions, you had to create the pipe using the mkfifo(1) command.

	Example 3.20. Using the pipe() driver
	destination d_pipe { pipe("/dev/xconsole"); };
