title: syslog-ng keep source hostname and last relay
body: <p>I have SSB and syslog-ng clients writing to it. I need to have in logs hostname of source of log (using <code>keep_hostname(yes)</code>) and IP of last relay, like with option <code>keep_hostname(no)</code> in log. I need both of them in the same log, how can I achieve that? </p>
