Input tcp does not close the connection

Elastic Stack Logstash
1

Hi

My problem is that the tcp plugin seems to keep a connection open instead of closing it after each call. Is this normal behaviour? We have a loadbalancer that constantly make GET requests to see that each node in the cluster is responding and it expects a 200 response but right now it get's nothing, only an connection that never closes.

Our input configuration looks like this and we are running logstash version 2.4.1

	tcp {
	port => 443
	codec => json
	ssl_enable => true
	ssl_cert => "abc.pem" 
    ssl_key => "abc.key"
	ssl_extra_chain_certs => ["def.pem"]
	ssl_verify => false
	tags => "ssl_transfer"
}

Regards
Tonni

The tcp input doesn't speak HTTP so the load balancer will never get a 200 response (or anything else for that matter).

Ah. So then we should use the http input for the loadbalancer and keep the tcp input for nxlog

Yes, that should work.
