nginx【6】用 GoAccess 实现可视化并实时监控 access 日志

1. 简介

access日志记录了Nginx非常重要的信息,我们可以使用Nginx来分析定位问题;也可以用它来分析用户的运行数据;但是如果想要实时分析access.log相对比较困难

有一款工具叫GoAccess,它可以以图像化的方式通过WebSoxket协议实时的把access.log的变迁反应到浏览器中方便我们分析问题;接下来我们来演示如何使用GoAccess工具来分析Nginx的access.log的日志中。

样板：

默认access.log

$ tail nginx/logs/host.access.log

2. 安装goaccess

不同方式安装请参考

 yum install goaccess

3. 启动goaccess

--log-format=COMBINED--log-format=COMBINEDgoaccess access.log -o report.html --log-format=COMBINEDhost.access.log

nginx.conf/report.htmlreport.html

上游服务配置添加：

$ vim nginx/conf/nginx.conf
.......
        location /report.html {
            alias /opt/openresty/nginx/html/report.html;
        }
.......

启动带参数的goaccess

$ goaccess nginx/logs/host.access.log  -o /opt/openresty/nginx/html/report.html --real-time-html --time-format='%H:%M:%S'--date-format='%d/%b/%Y' --log-format=COMBINED
