1.logstash问题报错的解决

1.

根据截图可知：ouput是输出到elasticsearch,具体的IP.你可以自己设定。我设定的是本地环境。也就是localhost：9200.

input{绑定应用以及端口，beats{}详细的去解析一下。

}先百度学习一下beats{}这个具体指的是什么东西。

方法：

查阅官方文档：

官网连接如下：

https://www.elastic.co/guide/en/logstash/current/introduction.html

具体输入的内部构造原理如下：

处理大数据的输入集如下操作：

注意一点logsash.conf也就是配置文件必须是ANSI文件格式的，不然会报错。

报错的错误如下：

ch::HttpClient::Pool::HostUnreachableError, :error=>"Elasticsearch Unreachable: [http://localhost:9200/][Manticore::SocketException] Connection refused: connect"}

logstash的配置文件默认文件编码必须要注意。
