Hi there,  
I have a logstash server, a elasticsearch server, a HA proxy server. I want to transfer data from LS to ES through HA proxy as flow:  
LS(10.0.0.2) ------\> HA proxy(172.0.0.2) -------\> ES(192.168.56.2)  
I just configed LS output as below:

> ```
> output {
> elasticsearch {
> hosts => ["172.0.0.2:9200"]
> manage_template => false
> index => "test"
> document_type => "%{[@metadata][type]}"
> }
> }
> 
> ```

I got the index in ES server but there are no data belong to it. The result as below:

> ```
> health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
> red open test d5KEDZdpSq2GsQ-D0KYneQ 5 1 <blank> <blank> <blank> <blank>
> 
> ```

So, how can i configure LS output to which ES can get data from LS through HA proxy?

Thanks.

Why is the health of the index red? Check your ES logs.

No special configuration should be necessary on the Logstash side. The whole point of HAproxy is to be a transparent proxy.

Well, that needs to be fixed. I suggest you consult the Elasticsearch group unless you can figure it out.
