This library writes messages formatted as per RFC5424, transmitted via UDP as described in RFC5426.
You can configure syslog-ng to receive these messages with the following directive:
syslog(transport("udp") port(514) keep_timestamp(yes));
make
0> syslog:start_link(name, app_name, "localhost", 514, local0).
ok
2> syslog:send(name, "test").
ok
3> syslog:notice(name, "other test").
ok
4> syslog:send(name, "test 3", [{timestamp, os:timestamp()}]).
ok
$ syslog
