-> 如果您在使用 Zabbix，有以下的场景，推荐您升级到夜莺：
+#### 如果您在使用 Zabbix，有以下的场景，推荐您升级到夜莺：

 - 监控的数据量太大，希望有更好的扩展解决方案；
 - 学习曲线高，多人多团队模式下，希望有更好的协同使用效率；
 - 微服务和云原生架构下，监控数据的生命周期多变、监控数据维度基数高，Zabbix 数据模型不易适配；

-> 如果您在使用 [Open-Falcon](https://github.com/open-falcon/falcon-plus)，我们更推荐您升级到夜莺：

+## 架构介绍
+
+<img src="doc/img/arch-product.png" width="680">
+
+Nightingale 可以接收各种采集器上报的监控数据（比如 [Categraf](https://github.com/flashcatcloud/categraf)、telegraf、grafana-agent、Prometheus），并写入多种流行的时序数据库中（可以支持Prometheus、M3DB、VictoriaMetrics、Thanos、TDEngine等），提供告警规则、屏蔽规则、订阅规则的配置能力，提供监控数据的查看能力，提供告警自愈机制（告警触发之后自动回调某个webhook地址或者执行某个脚本），提供历史告警事件的存储管理、分组查看的能力。

+<img src="doc/img/arch-system.png" width="680">

 夜莺 v5 版本的设计非常简单，核心是 server 和 webapi 两个模块，webapi 无状态，放到中心端，承接前端请求，将用户配置写入数据库；server 是告警引擎和数据转发模块，一般随着时序库走，一个时序库就对应一套 server，每套 server 可以只用一个实例，也可以多个实例组成集群，server 可以接收 Categraf、Telegraf、Grafana-Agent、Datadog-Agent、Falcon-Plugins 上报的数据，写入后端时序库，周期性从数据库同步告警规则，然后查询时序库做告警判断。每套 server 依赖一个 redis。

-如果单机版本的时序数据库（比如 Prometheus） 性能有瓶颈或容灾较差，我们推荐使用 [VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics)，VictoriaMetrics 架构较为简单，性能优异，易于部署和运维，架构图如上。VictoriaMetrics 更详尽的文档，还请参考其[官网](https://victoriametrics.com/)。

-# 告警消息模版文件
-
-模版中可以使用的变量参考`AlertCurEvent`对象
-模版语法如何使用可以参考[html/template](https://pkg.go.dev/html/template)
-
-## 如何在告警模版中添加监控详情url
-
-假设web的地址是http://127.0.0.1:18000/, 实际使用时用web地址替换该地址
-
-在监控模版中添加以下行:
-
-* dingtalk / wecom / feishu
-```markdown
-[监控详情](http://127.0.0.1:18000/metric/explorer?promql={{ .PromQl | escape }})
-```
-
-* mailbody
-
-```html
-<tr>
-  <th>监控详情：</th>
-  <td>
-    <a href="http://127.0.0.1:18000/metric/explorer?promql={{ .PromQl | escape }}" target="_blank">点击查看</a>
