Hi,  
I'm trying to insert documents into an Elasticsearch index from a filebeat, through Logstash processing.  
My Logstash config looks like this:  
input {  
beats {  
port =\> 5044  
}  
}  
output {  
elasticsearch {  
hosts =\> ["localhost:9200"]  
index =\> ["logstash-%{+YYYY.MM.dd}"]  
}  
}

The problem I have is that Elasticsearch then creates the index named:  
logstash-0018.01.16  
And I can't find any data in this index.

Does anyone know what's wrong with this config?
