Hi, I'm using syslog-ng 3.18.1, and I'm having some issues due to my special use case.

Unfortunately my syslog-ng agent reads some binary files which are piped through the log file I'm processing and sending it to elasticsearch. When this happens, the elastic bulk post fail (So I'am affected by this issue https://github.com/balabit/syslog-ng/issues/1993). I've debugged it and the problem was that message generated when applying the template is empty.

This is my network destination:

destination d_syslog_tcp {
    network(

        "syslog-relay.node"

        port(7601)
        template("${ISODATE} ${HOST} ${CONTAINER-IP} ${MESSAGE}\n")
        template-escape(no)
        disk-buffer(
            mem-buf-size(200M)
            disk-buf-size(500M)
            reliable(yes)
            dir("/var/syslog-ng")
        )
    );
};
