unix-stream() Source Driver

The unix-stream() driver open an AF_UNIX socket and start listening on it for messages. The unix-stream() driver uses SOCK_STREAM semantics.

Important Information

In the official documentation, /dev/log is the default entry for system logging. This, in fact, is a socket, not a regular file or a pipe. MacOS, however, uses /var/run/syslog for the same. This needs to be kept in mind while referring to the documentation.

Configuration File Used

@version: 3.31
@include "scl.conf"

options {
    stats-freq(10);
    time-reopen(10);
};

source s_stream {
    unix-stream("/var/run/syslog");
};

destination console{
    file(/dev/stdout);
};

log {
    source(s_stream);
    destination(console);
};

Proof

Note : unix-stream() does not support multiple lines as the record separator is the NL character, so if you embed “\n” in the log message, they will become separate messages.
