处理redis日志展示

ELK之-redis(错误,警告)日志使用filebeat收集

收集redis警告和错误日志即可
filebeat
   include_lines: ["WARNING","ERROR"]
         include_lines 一个正则表达式的列表,以匹配您希望Filebeat包含的行。Filebeat仅导出与列表中正则表达式匹配的行。默认情况下,导出所有行。

filebeat安装配置

[root@elk-node01 var]# wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-6.6.0-x86_64.rpm
[root@elk-node01 var]# yum install filebeat-6.6.0-x86_64.rpm
    [root@elk-node01 var]# cat /etc/filebeat/filebeat.yml
       #主要通过log_type来判断

启动检查数据

[root@elk-node01 config]# /etc/init.d/filebeat restart 
 Restarting filebeat (via systemctl):                       [  OK  ]
