syslog-ng Open Source Edition 3.16 - Release Notes

stdin: Collecting messages from the standard input stream

stdin: Collecting messages from the standard input stream

The stdin() driver collects messages from the standard input stream. When the standard input stream is closed, syslog-ng stops and stdin() inherits all options from the file() source, including multi-line options, or flags(no-parse).

The stdin() driver causes syslog-ng to exit once it hits end-of-file (EOF).

Declaration:
stdin();
Example: Using the stdin() driver
@version: 3.16
log { 
	source { stdin(); };
	destination { file("/dev/stdout"); };
};

The following code snippet is an example of how the stdin() driver is used to collect a test message:

$ echo "this is a test message" | ./syslog-ng -Fe --no-caps

[2017-11-14T13:47:16.758195] syslog-ng shutting down; version='3.12.1'
