using logstash 2.3.4

Hello! Newbie to Logstash. Trying to figure out how I should format the input that the sflow codec would accept.

so far all I get is (per line of text in my sflow.input file):

Ignoring Sflow version v808728112 {:level=\>:warn}  
Ignoring Sflow version v808728112 {:level=\>:warn}  
Ignoring Sflow version v808728112 {:level=\>:warn}  
...

Here's my sflow.conf config:  
input {  
file{  
path =\> "/home/arista/sflow.input"  
codec =\> sflow{}  
start\_position =\> "beginning"  
sincedb\_path =\> "/dev/null"  
}  
stdin{}  
}

output {  
file{  
path =\> "/home/arista/output.log"  
}  
stdout{}  
}

I've tried feeding it ascii based human readable text of the packet as well as the binary representation of that text. Neither option worked.

Could someone please walk me through what I need to feed this code so it accepts the input?

BTW, the sflow input is definitely Sflow v5.

Thanks!
