Hello Everyone,

I am trying to integrate ELK Stack 5.6.4 in RHEL 7 with ArcSight smartconnector with this link:  
[https://www.elastic.co/guide/en/logstash/5.6/arcsight-module.html#arcsight-instructions-smartconnector](https://www.elastic.co/guide/en/logstash/5.6/arcsight-module.html#arcsight-instructions-smartconnector)

After completion of integration we are getting this:

[2018-01-23T15:39:30,142][WARN][logstash.outputs.elasticsearch] Attempted to resurrect connection to dead ES instance, but got an error. {:url=\>"[http://logstash\_system:xxxxxx@localhost:9200/](http://logstash_system:xxxxxx@localhost:9200/)", :error\_type=\>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :error=\>"Elasticsearch Unreachable: [[http://logstash\_system:xxxxxx@localhost:9200/](http://logstash_system:xxxxxx@localhost:9200/)][Manticore::SocketException] Connection refused (Connection refused)"}

I have installed x-pack in elasticsearch, logstasha and kibana.

Thnks & Regards,  
Krunal.

Logstash is trying to connect to localhost:9200. Is that where you're running ES?

That doesn't really answer my question, but make sure all aspects of Logstash (all elasticsearch outputs and the X-Pack monitoring configuration in logstash.yml) is configured to connect to wherever ES is running.
