Redis input socketerror, Error: initialize: name or service not known

[layla]

I have configured a logstash before the log comes to elasticache for redis, below is the configuration and I can send the syslog to elasticache for redis successfully.

indent preformatted text by 4 spaces
 input {
    stdin {
    }
}

output {
    redis {
            host => "amazonaws.com:6379"
            data_type => "list"
            key => "logstash"
    }
} 

However, I also put an instance after elasticache for redis, I have set below configuration but logstash cannot get the data from elasticache, and I have also get the below error from logstash log. Please kindly help!

input {
    redis {
            host => "amazonaws.com:6379"
            #type => "redis-input"
            data_type => "list"
            key => "logstash"
            codec => "json"
    }
}

output {
    amazon_es {
            hosts => "ap-southeast-1.es.amazonaws.com"
            region => "ap-southeast-1"
            aws_access_key_id =>'######'
            aws_secret_access_key => '######'
    }
}

The hostname in the redis input isn't the same as in the redis output. The latter resolves correctly in DNS but the former doesn't.

Oh yes!! Thanks for pointing out the mistake! It works now!
