EC2 中的 Logstash 无法将日志数据发送到 AWS Elasticsearch 服务

Question

在 EC2 中，我将 logstash 配置如下

input {
#       beats{
#       port => 5044
# }


  file {
        type => "adjustlog"
        path => "/etc/logstash/conf.d/sample.log"
        start_position => "beginning"
        sincedb_path => "/dev/null"
  }

}

filter {
        if[type] == 'adjustlog'{
                grok {
                    match => {
        "message" => [
           "%{TIMESTAMP_ISO8601:timestamp},(%{USERNAME:userId})?,%{USERNAME:setlkey},%{USERNAME:uniqueId},%{NUMBER:providerId},%{USERNAME:itemCode},%{USERNAME:voucherCode},%{USERNAME:samsCode},(%{USERNAME:serviceType})?"
        ]
                }
        }
        }else {
        drop{ }
        }
}


output {
elasticsearch{
               hosts => ["search-*.es.amazonaws.com:80"]
                index => "test"
                }
 stdout {codec => rubydebug}

}

但 logstash 无法在 AWS elasticsearch 中创建索引，并且 发送日志数据。 （但是，curl 和 wget 命令运行良好。 我可以使用 curl 命令创建索引）

调试的检查点是什么？

我在尝试解决类似问题时发现了这一点。 AWS 改变了它实现 Elasticsearch 节点发现的方式。它会正常工作，直到 logstash 尝试发现更多主机时它会中断。暂时但不一致地重新启动 logstash 可以解决此问题。 curl 和 wget 也可以正常工作。

:message=>"Cannot get new connection from pool.", :class=>"Elasticsearch::Transport::Transport::Error", :backtrace=>["/opt/logstash/vendor/bundle/jruby/1.9/gems/elasticsearch-transport-1.0.15/lib/elasticsearch/transport/transport/base.rb:193:in `perform_request'",

ElasticSearch 会工作一段时间，但随后会停止摄取数据。

失败的旧配置

output {
  elasticsearch {
    hosts => ["https://search-*.us-east-1.es.amazonaws.com"]
    sniffing => true
    manage_template => false
    index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
    document_type => "%{[@metadata][type]}"
  }
}

Logstash 尝试从 Elasticsearch 获取主机列表，但 AWS 的实施改变了返回数据的格式。有关详细信息的更多详细信息。 https://forums.aws.amazon.com/thread.jspa?threadID=222600 https://discuss.elastic.co/t/elasitcsearch-ruby-raises-cannot-get-new-connection-from-pool-error/36252/11

工作配置。

output
 {
  elasticsearch {
    hosts => ["https://search-*.us-east-1.es.amazonaws.com"]
    manage_template => false
    index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
    document_type => "%{[@metadata][type]}"
  }
}
