Logstash 在运行时出现异常

Question

当我运行它时，我在 logstash 日志中得到了这个异常。

[2018-01-14T15:42:00,912] [错误][logstash.outputs.elasticsearch] 弹性搜索的未知设置“主机” [2018-01-14T15:42:00,921][ERROR][logstash.agent] 无法执行动作 {:action=>LogStash::PipelineAction::Create/ pipeline_id:main, :exception=>"LogStash::ConfigurationError", :message=>"您的配置有问题。", :backtrace=>["/usr/share/logstash/logstash-core/lib/logstash/config

这是我的配置：

   input{
 lumberjack {
  port => 5044
  type => "logs"
  ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt"
  ssl_key => "/etc/pki/tls/private/logstash-forwarder.key"
 }    
}


filter{
 if[type] == "syslog" {
   grok {
    match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:sysylog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}" }
     add_field => ["received_at", "%{@timestamp}" ] 
     add_field => ["received_from", "%{host}" ]
   }
   syslog_pri {}
   date {
     match => ["syslog_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss" ]
   }
 }
}

output{
  elasticsearch { host =>localhost }
  stdout { codec => rubydebug }
}

我该如何解决。谢谢。 我使用最新版本的 ELK

如果您检查您的输出弹性搜索插件，它有主机参数。
它需要一个主机参数和一个字符串数组。
https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-hosts
我的 logstash->elastic 插件如下所示：

elasticsearch{
  hosts=>["localhost:9200"]
  index=>"logstash-%{+YYYY.MM.dd}"
}

您可能也需要设置索引参数。
