业务场景

最近在做CA卡相关业务处理，用户量700w，对于相关操作日志，按照传统的方式显然不合理的，出现问题排查也是个事，最后我考虑通过Logstash直接全写到es内，下面我就简单写一下我怎么弄的，当然还有很多别的可以实现：例如 Filebeat等。

安装部署

安装Logstash，之前通过docker安装过，这里我使用安装包的方式。

访问链接，下载文件

https://www.elastic.co/cn/downloads/past-releases

选择对应的产品及版本

安装完成～～～

定制化配置

1.创建文件

/work/elasticsearch/logstash-7.1.0/config/logstash-omc.conf

2.日志打印例子

2020-01-14 17:13:18,419 DEBUG http-bio-8082-exec-1 - {"createAt":"2020-01-14 17:13:03","status":"0","developer":null,"servid":"760000","action":"UPDATE","devno":"keyno01","devtype":1,"modifyAt":"2020-01-14 17:13:03","accountid":"131022","servstatus":null,"uapuserid":"152022","serialno":"76a58c28cff741aba621a6098cebaf6c"}

3.logstash-omc.conf 编写配置文件例子

# Sample Logstash configuration for creating a simple
# Beats -> Logstash -> Elasticsearch pipeline.

input {
  file{
      #配置相关业务日志全部存入此文件
      path=>["/work/docker/bandDev.log"]
      type=>"apache-log"
      start_position => "beginning"
      ignore_older => 0
  }
}

filter {
    grok {
        match => {
            #正则表达式 根据日志打印格式编写
            "message" => ["([\s\S]*) (?<Msg>({.*?}))"]
        }
        #覆盖之前的message
        overwrite => ["message"]
        #去除无用的字段
        remove_field => ["host","beat","offset"]
    }

    json{
        source => "Msg"
        target => "xa"
    }
}

output {
  elasticsearch {
    #es的连接地址
    hosts => ["localhost:9200"]
    #es中的索引名称
    index => "xa-logstash"
    #user => "elastic"
    #password => "changeme"
  }

启动Logstash

#进入bin目录下
e24-6:bin dailong$ pwd
/work/elasticsearch/logstash-7.1.0/bin
e24-6:bin dailong$ ./logstash -f /work/elasticsearch/logstash-7.1.0/config/logstash-omc.conf

logstash就是类似于咱的Listener，一个监听器，监听这个文件的变化，当变化了会根据咱之前写的那个配置文件的格式往es写数据。
