+## 🎡 <font color="green">介绍</font>
+
+> [HertzBeat赫兹跳动](https://github.com/dromara/hertzbeat) 是一个拥有强大自定义监控能力，无需 Agent 的开源实时监控告警工具。     
+> 集 **监控+告警+通知** 为一体，支持对应用服务，数据库，操作系统，中间件，云原生，网络等监控，阈值告警通知一步到位。   
+> 更自由化的阈值规则(计算表达式)，`邮件` `Discord` `Slack` `Telegram` `钉钉` `微信` `飞书` `短信` `Webhook` 等方式及时送达。
+
+> 我们将`Http,Jmx,Ssh,Snmp,Jdbc`等协议规范可配置化，您只需在浏览器配置`YML`就能使用这些协议去自定义采集任何您想要的指标。    
+> 您相信只需配置下就能立刻适配一款`K8s`或`Docker`等新的监控类型吗？
+
+> `HertzBeat`的强大自定义，多类型支持，易扩展，低耦合，希望能帮助开发者和中小团队快速搭建自有监控系统。    
+> 当然我们也提供了对应的 **[SAAS版本监控云](https://console.tancloud.cn)**，中小团队和个人无需再为了监控自己的网站资源，而去部署学习一套繁琐的监控系统，**[登录即可免费开始](https://console.tancloud.cn)**。

+## 镜像部署  
+
+> HertzBeat支持在Linux Windows Mac系统安装运行，CPU支持X86/ARM64。 
+
+1. 开通服务器时选用 HertzBeat 镜像
+2. 启动服务器
+3. 配置HertzBeat的配置文件(可选)
+
+   修改位于 `/opt/hertzbeat/config/application.yml` 的配置文件(可选)，您可以根据需求修改配置文件
+   - 若需使用邮件发送告警，需替换`application.yml`里面的邮件服务器参数
+   - **推荐**若需使用外置Mysql数据库替换内置H2数据库，需替换`application.yml`里面的`spring.datasource`参数 具体步骤参见 [H2数据库切换为MYSQL](../start/mysql-change)）
+   - **推荐**若需使用时序数据库TDengine来存储指标数据，需替换`application.yml`里面的`warehouse.store.td-engine`参数 具体步骤参见 [使用TDengine存储指标数据](../start/tdengine-init)
+   - **推荐**若需使用时序数据库IotDB来存储指标数据库，需替换`application.yml`里面的`warehouse.storeiot-db`参数 具体步骤参见 [使用IotDB存储指标数据](../start/iotdb-init)
+
+
+4. 配置用户配置文件(可选,自定义配置用户密码)     
+   HertzBeat默认内置三个用户账户,分别为 admin/hertzbeat tom/hertzbeat guest/hertzbeat     
+   若需要新增删除修改账户或密码，可以通过修改位于 `/opt/hertzbeat/config/sureness.yml` 的配置文件实现，若无此需求可忽略此步骤     
+   具体参考 [配置修改账户密码](../start/account-modify)
+
+5. 部署启动
+   执行位于安装目录/opt/hertzbeat/bin/下的启动脚本 startup.sh, windows环境下为 startup.bat
+   ``` 
+   $ ./startup.sh 
+   ```
+
+6. 开始探索HertzBeat  
+   浏览器访问 http://ip:1157/ 即刻开始探索使用HertzBeat，默认账户密码 admin/hertzbeat。
+
+**HAVE FUN**
+
+### 部署常见问题
+
+**最多的问题就是网络问题，请先提前排查**
+
+1. **按照流程部署，访问 http://ip:1157/ 无界面**   
+   请参考下面几点排查问题：
+> 一：若切换了依赖服务MYSQL数据库，排查数据库是否成功创建，是否启动成功
+> 二：HertzBeat的配置文件 `hertzbeat/config/application.yml` 里面的依赖服务IP账户密码等配置是否正确    
+> 三：若都无问题可以查看 `hertzbeat/logs/` 目录下面的运行日志是否有明显错误，提issue或交流群或社区反馈
+
+2. **监控历史图表长时间都一直无数据**
+> 一：Tdengine或IoTDB是否配置，未配置则无历史图表数据  
+> 二：若使用了Tdengine，排查Tdengine的数据库`hertzbeat`是否创建
+> 三: HertzBeat的配置文件 `application.yml` 里面的依赖服务 IotDB 或 Tdengine IP账户密码等配置是否正确
