# 【告警系统接入PrometheusAlert配置】

***

PrometheusAlert的原理就是通过自定义模版接口`/prometheusalert`接收各种告警系统或者任何带有WebHook功能的系统发来的消息，然后将收到的消息经过自定义模板渲染成消息文本，最终转发给不同的接收目标。

一般情况下如果使用的是钉钉，企业微信、飞书等机器人作为接收目标的，可以不去配置PrometheusAlert的配置文件app.conf；但是如果需要使用如短信，电话，邮箱等功能，则需要先配置好app.conf中的相关配置项方可使用。

#### 系统接入PrometheusAlert流程参考

* 1.安装好PrometheusAlert 参考：[安装部署PrometheusAlert](/prometheusalert/base-install.md)
* 2.配置 app.conf \[可选] 参考：[【 app.conf 默认参数配置】](/prometheusalert/conf.md)
* 3.配置告警系统接入PrometheusAlert

#### PrometheusAlert处理告警消息原理

`XXX-WebHook` --> `POST-JSON` --> `/prometheusalert?type=dd&tpl=prometheus-dingding&ddurl=https://oapi.dingtalk.com/robot/send?access_token=xxxx` --> `PrometheusAlert通过tpl模版prometheus-dingding渲染收到的JSON` --> `将渲染后的消息文本发送给https://oapi.dingtalk.com/robot/send?access_token=xxxx` --> `钉钉机器人完成告警`

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://feiyu563.gitbook.io/prometheusalert/system.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
