+
+在开始之前，我们需要了解策略的基本概念。
+
+## 什么是策略？
+
+策略是一组规则的集合，用于去检测和报警系统中的指标。
+
+## 需要哪些东西？
+
+1. 什么场景的告警策略？
+2. 告警给谁？
+3. 怎么展示？
+
+针对上述问题，我们可以设计以下策略：
+
+1. 系统 CPU 使用率过高：当系统 CPU 使用率超过 80% 时，发送邮件给管理员。
+
+## 创建Hook
+
+> Hook 是 Moon 用来与外部系统集成的一种方式。Moon 支持多种类型的 Hook，包括邮件、短信、电话、企业微信、飞书等。
+
+![Hook](./img/hook-add.png)
+
+## 创建告警通知组
+
+> 告警组是用于管理通知渠道的集合。里面包含人员（邮件、短信、电话）， Hook(Webhook、 DingTalk、企业微信、飞书等)
+
+* 登录到 Moon 控制台，点击左侧导航栏的“告警通知->告警组”，点击“添加”按钮。

+
+## 创建数据源
+
+* 登录到 Moon 控制台，点击左侧导航栏的“数据源->Metric”，点击“新建数据源”按钮。
+

+
+## 创建策略组
+
+> 策略组是策略的集合，可以定义多个策略，每个策略可以关联多个数据源。
+
+* 登录到 Moon 控制台，点击左侧导航栏的“策略管理->策略组”，点击“添加”按钮。

+
+* 登录到 Moon 控制台，点击左侧导航栏的“策略管理->策略列表”，点击“添加”按钮。

+
+## 告警恢复
+
+> 这里是修改策略的阈值为100%，告警恢复。也可以直接关闭策略来产生告警恢复事件
