Hi,  
I have set up a logstash input for syslog:

```
syslog {
    port => 6514
    codec => cef
    tags => ["syslog"]
}

```

I have different kind of syslogs running through that input.  
I have messages that arrives in cef format, and other that arrive in simple syslog format.  
The problem is when I get regular syslog messages ofcourse the cef codec fails. and thats ok.  
but it spams the logstash-plain and it becomes impossible to debug other problems with that much spam going on.  
Is it possible to suppress errors from that specific input?

I do not think you can suppress the [error](https://github.com/logstash-plugins/logstash-codec-cef/blob/2a8edcd5095e811cebfb5d48134eeb32de267067/lib/logstash/codecs/cef.rb#L335), but if you can determine which messages are in cef format you can [route them to a different pipeline](https://discuss.elastic.co/t/logstash-configuration-input-error-with-if-statement/246019/8) and use the codec on that.
