    PollInterval 1
    SavePos	True
    ReadFromLast True
    Recursive False
    RenameCheck True
    Exec $FileName = file_name(); # Send file name with each message
</Input>

<Output 578f97f40ae2f10b1139b093>
    Module om_udp
    Host 192.168.20.210
    Port 5441

    Exec $short_message = $raw_event; # Avoids truncation of the short_message field.
    Exec $gl2_source_collector = 'ae1187a3-48ae-42bc-a820-7033d7438dbd';
    Exec $Hostname = hostname_fqdn();
</Output>
