input{  
file{  
type =\> "log"  
codec =\> "json"  
path =\> "/var/log/test.log"  
start\_position =\> "beginning"  
sincedb\_path =\> "/var/test/sincedb/.sincedb\_log"  
}

filter {

grok {  
match =\> ["message", "%{SYSLOGBASE} %{URIPATH:url}%{GREEDYDATA:datagreedy}"]  
}

if "[http://google.com](http://google.com)" == [url]{  
metrics{  
meter =\> "google\_events"  
add\_tag =\> "google"  
}  
}  
}

output{

if "google" in [tags]{  
stdout {  
codec =\> line { format =\> "count: %{[google\_events][count]} - %[message]"  
}  
}  
elasticsearch {  
index =\> "test"  
hosts =\> ["[http://localhost:9200](http://localhost:9200)"]  
}  
}

How do you know the `url` field is ever equal to "[http://google.com](http://google.com)"?

Only if url field is "[http://google.com](http://google.com)" I want a google event message on standard output that don't work because %[message] on standard output is empty. Elasticsearch upload is work fine because I upload all events.
