     告警规则的rule的数据  就是这里的查询语句查询出来的结果

## Request timeout
# timeout: 5s

## Uncomment following line in order to write template from scratch (be careful!)
#no_builtin_template: true

## Customizable templates path
templates:
  - contrib/templates/legacy/template.tmpl

## You can also override default template using `default_message`
## The following example to use the 'legacy' template from v0.3.0
#default_message:
#  title: '{{ template "legacy.title" . }}'
#  text: '{{ template "legacy.content" . }}'

## Targets, previously was known as "profiles"
targets:
  webhook1:
    url: https://oapi.dingtalk.com/robot/send?access_token=7f7fe25
    # secret for signature
    secret: 4ee16602f4108eb793475803cfa26a1be5210ccf1

    需单独安装  prometheus-webhook-dingtalk-2.1.0.linux-amd64组件

内网代理钉钉消息

     内网中只有一台机器可以联网

     监控的主机无法连接外部的机器

     给prometheus-webhook-dingtalk进程设置代理地址环境变量   不能设置成系统变量,因为这样会影响系统上所有的https请求

     

     添加进程环境变量

      //在程序启动的时候注入多个环境变量
      export https_proxy=http://ct:kXoNx@10.30.90.15:3128 && export http_proxy=http://cta:kgX3Nx@10.30.90.15:3128 && ./prometheus-webhook-dingtalk --config.file=config.yml

     

     

     

      1.把代理地址做为环境变量注入到指定的进程中

         //在程序启动的时候注入一个环境变量
         export https_proxy=http://aaaaa:22222@10.30.90.1:3128 && ./prometheus-webhook-dingtalk --config.file=config.yml

        //在程序启动的时候注入多个环境变量
        export https_proxy=http://ct:kXoNx@10.30.90.15:3128 && export http_proxy=http://cta:k8TgX3Nx@10.30.90.15:3128 && ./prometheus-webhook-dingtalk --config.file=config.yml

       2.查看进程的环境变量

          ps -ef | grep webhook

          cat /proc/5663/environ | tr '\0' '\n'

          cat /proc/5663/comm
