I have been trying to connect a Graylog sever with Amazon’s Elastic search service.i have updated the Elasticsearch’s endpoint in the Graylog Config file as well.I can see Graylog Server is running but am not able to connect to Elastic search.Is it really possible to connect a Graylog server with Amazon’s Elastic search service???
I would recommend you to access your es cluster using curl or other methods from the graylog server or at best the same subnet or network. To make sure your elasticsearch service is accessible without any additional authentication or isn’t being protected by AWS access policies.
