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"}

According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

logstash的配置文件默认文件编码必须要注意。
