Hi All,  
Can't understand why logstash suddenly writes all input to logstash.log?  
Is that some new feature in logstash 1.5?

My output config look like this:  
output {  
elasticsearch {  
host =\> "X.X.X.X"  
port =\> "9200"  
protocol =\> "http"  
cluster =\> "elastic-XXX-cluster"

I haven't seen this behavior before?  
Any idea how to turn this off?

Br  
Mathias

Ah, got hit by the following issue, that's what's filling my logs:  
elasticsearch output - failed with response of 400
