stdin: Collect messages from the standard input stream

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

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

Declaration:

   stdin(); 

Example: Using the stdin() driver

   @version: 4.26
    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
    [2017-11-14T13:47:16.757938] syslog-ng starting up; version='3.12.1'
    [2017-11-14T13:47:16.758195] syslog-ng shutting down; version='3.12.1'
