I am a logstash noob, and have been trying to find the answer for a few hours now, searching here and all over google. Please forgive me if my question has been asked and answered - I'm starting to see double..

I have a Logstash/Elasticsearch/Kibana setup and running, and have my index configured, however - I am not able to determine why I don't see any of the syslog severity or facility codes. I am pretty sure its a grok filtering issue, but as I mentioned, I'm a noob, and I haven't figured it out yet.

Can someone point me in the right direction about a filter to use? I am using a pretty basic one now -

filter {  
if [type] == "syslog" {  
grok {  
match =\> { "message" =\> "%{SYSLOGTIMESTAMP:syslog\_timestamp} %{SYSLOGHOST:syslog\_hostname} %{DATA:syslog\_program}(?:[%{POSINT:syslog\_pid}])?: %{GREEDYDATA:syslog\_message}" }  
add\_field =\> ["received\_at", "%{@timestamp}"]  
add\_field =\> ["received\_from", "%{host}"]  
}  
syslog\_pri { }  
date {  
match =\> ["syslog\_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss"]  
}  
}  
}

Is the `syslog_pri` field set anywhere? That (configurable) field is used by the syslog\_pri filter to populate the facility and severity fields. You're not setting it in the grok filter so unless it's set by the input I don't know how this is supposed to work.
