I would like to know if is it possible to send subject field to rsyslog server. Eg: subject : " username " should be sent.

According to the [documentation](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-syslog.html#plugins-outputs-syslog-options), it's not possible even as a tag. You might try to add somehow is the message and parse on rsyslog side.
