ELK之-redis(错误,警告)日志使用filebeat收集

处理redis日志展示

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。 参考：https://www.elastic.co/guide/en/beats/filebeat/current/configuration-filebeat-options.html

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 filebeat.prospectors: - input_type: log paths: - /data/wwwlogs/access_nginx.log fields: log_source: nginx log_type: nginx - input_type: log paths: - /var/log/messages fields: log_source: messages log_type: messages - input_type: log paths: - /usr/local/redis/var/redis.log include_lines: ["WARNING","ERROR"] fields: log_source: redis log_type: redis output.redis: hosts: ["127.0.0.1:6379"] key: "defaul_list" db: 5 timeout: 5

logstash配置
