WAF日志告警配置案例 - Web 应用防火墙

本文提供了典型的Web应用防火墙（WAF）日志查询与分析告警配置案例。您可以参考本文提供的告警配置参数，在自定义WAF日志仪表盘中添加监控图表及配置告警。

重要

本文以旧版日志服务告警配置为例，介绍相关配置参数。如果您已升级使用了新版日志服务告警，请结合本文提供的查询语句及告警参数建议，并参见快速设置日志告警来完成相关配置。

该图表包含以下字段：aveQPS、2XX比例、3XX比例、4XX比例、5XX比例，分别表示域名QPS和各类型响应状态码的占比。其中，4XX比例不包含WAF拦截的CC攻击和Web攻击等造成的444和405状态码，以便只展示因业务自身原因造成的状态码变化。在设置告警触发条件时，您可以自由组合上述字段。例如，aveQPS>10 && 2XX比例<60表示在设定的统计时间内，指定域名的QPS达到10以上且2XX比例小于60%。
