使用须知

使用本参考前，您必须已完成创建WAF日志分析仪表盘。更多信息，请参见步骤1：创建WAF日志分析仪表盘。

关于在仪表盘中配置图表的步骤，请参见步骤2：配置日志图表。
关于在仪表盘中配置告警的步骤，请参见步骤3：配置日志告警。

本参考提供以下13个告警配置范例。


序号	告警场景
1	4XX比例异常告警
2	5XX比例异常告警
3	QPS异常告警
4	QPS突增告警
5	QPS突降告警
6	5分钟内ACL拦截情况告警
7	5分钟内WAF拦截情况告警
8	5分钟内CC拦截情况告警
9	5分钟内扫描拦截情况告警
10	单IP攻击量预警
11	单IP攻击域名数量告警
12	5分钟平均时延情况
13	UID维度流量突降告警

4XX比例异常告警

告警参数配置建议：

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%。

查询区间：建议设置为5分钟
