Hi, I'm trying to parse some apache logs like this:

```auto
46.105.14.53 - - [20/May/2015:21:05:15 +0000] "GET /blog/tags/puppet?flav=rss20 HTTP/1.1" 200 14872 "-" "UniversalFeedParser/4.2-pre-314-svn +http://feedparser.org/"

```

Filebeat is fetching logs and they are going through Logstash, Elasticsearch and Kibana correctly.  
Here is my logstash.conf:

```auto
input {
  beats {
    port => 5044
  }
}
filter {
    grok {
      match => {"message" => "%{IPORHOST:clientip}"}
      remove_field => ["message"]
    }
}
output {
  elasticsearch {
    hosts => ["localhost:9200"]
    index => "%{[@metadata][beat]}-%{[@metadata][version]}"
  }
}

```

Here I'm trying to use a very simple Grok pattern that works on Grok Debugger. On Kibana I have the entire "message" field as if no filter has been applied.

Any help would be really appreciated.  
Thank you, regards.
