I would like to forward syslog from many device cisco to a siem using logstash.  
I tried to use syslog plugin but logstash insert a message into log and don't forward only the syslog message.

this is the part of logstash config output:  
output{  
syslog {  
facility =\> ["syslogd"]  
host =\> ["192.168.1.90"]  
port =\> 514  
severity =\> ["notice"]  
}  
}

```
this is the syslog that logstash receive
Msg:<14>Aug 07 17:58:06 accesslog: Info: 1533657485.836 222 10.54.5.1 TCP_CLIENT_REFRESH_MISS/200 306 GET http://google.com:443/ <-,-,-,"-",-,-,-,-,"-",-,-,-,"-",-,-,"-","-",-,-,-,-,"-","-","-","-","-","-",11.03,0,-,"-","-",-,"-",-,-,"-","-",-,-,"-"> - 51.14.141.128\0x0a

This is the syslog that logstash forward:
Msg: Aug 07 15:58:06 %{host} LOGSTASH[-]:<14>Aug 07 17:58:06 accesslog: Info: 1533657485.836 222 10.54.5.1 TCP_CLIENT_REFRESH_MISS/200 306 GET http://google.com:443/ <-,-,-,"-",-,-,-,-,"-",-,-,-,"-",-,-,"-","-",-,-,-,-,"-","-","-","-","-","-",11.03,0,-,"-","-",-,"-",-,-,"-","-",-,-,"-"> - 51.14.141.128\0x0a

```

As you can see logstash insert

`Aug 07 15:58:06 %{host} LOGSTASH[-]`

I would like to forward the first original syslog

Specify a codec with a format. For example,

```
output {
    syslog {
         codec => plain { format => "%{message}" }
    ...
```

I tried to use upd plugin output but also in this case into message I have this:

Original

```auto
"<159>ago 08 11:23:35 100.149.40.214 message.."

```

Forwarded message

```auto
Aug 8 12:21:27 192.168.11.218 {"message": "<159>ago 08 11:23:35 100.149.40.214 message.."

```
