ELK logstash 处理MySQL慢查询日志（初步）

写在前面：在做ELK logstash 处理MySQL慢查询日志的时候出现的问题：

1、测试数据库没有慢日志，所以没有日志信息，导致 IP：9200/_plugin/head/界面异常（忽然出现日志数据，删除索引后就消失了）

2、处理日志脚本问题

3、目前单节点

 

配置脚本文件/usr/local/logstash-2.3.0/config/slowlog.conf【详细脚本文件见最后】

 

output {

  elasticsearch {

    hosts => "115.28.3.150:9200"

    index => "mysql-slowlog"

    workers => 1

    flush_size => 20000

    idle_flush_time => 10

    template_overwrite => true

  }

}

在outpout定义Elasticsearch的IP与端口，以及索引名称

[root@iZ28o76f668Z config]# ../bin/logstash agent -f slowlog.conf

Settings: Default pipeline workers: 1

Pipeline main started

在http://115.28.3.150:9200/_plugin/head/页面上刷新：
