### alertmanager的配置文件 ###

global:
      smtp_smarthost: 'localhost:25'
      smtp_from: 'alertmanager@example.org'         #用于邮件通知的P发件人
    route:                                          #每个输入警报进入根路由
      receiver: 'team-X-mails'                      #根路由不得包含任何匹配项，因为它是所有警报的入口点
      group_by: ['alertname', 'cluster']            #将传入警报分组的标签。默认以告警名进行分组,就是rule文件的alert值进行分组
      group_wait: 30s                               #当传入的警报创建了一组新的警报时，请至少等待多少秒发送初始通知
      group_interval: 5m                            #发送第一个通知时，请等待多少分钟发送一批已开始为该组触发的新警报
      repeat_interval: 3h                           #如果警报已成功发送，请等待多少小时以重新发送警报
      routes:                                       #子路由，父路由的所有属性都会被子路由继承
        - match:
            severity: critical
          receiver: team-X-pager
    #如果另一个警报正在触发，则禁止规则允许将一组警报静音，如果同一警报已经严重，我们将使用此选项禁用任何警告级别的通知 
    inhibit_rules:
    - source_match:
        severity: 'critical'
      target_match:
        severity: 'warning'
      equal: ['alertname']
    #如果警报名称相同，则应用抑制，如果源警报和目标警报中均缺少“equal”中列出的所有标签名称，则将应用禁止规则！
    receivers:
    - name: 'team-X-mails'
      email_configs:
      - to: 'team-X+alerts@example.org, team-Y+alerts@example.org'
    - name: 'team-X-pager'
      email_configs:
      - to: 'team-X+alerts-critical@example.org'
      pagerduty_configs:
      - routing_key: <team-X-key>

### 实际配置 ###

global:
      smtp_smarthost: 'smtp.qq.com:465'  #发件人对应邮件提供商的smtp地址
      smtp_from: '327721596@qq.com'      #发件人邮箱地址
      smtp_auth_username: '327721596@qq.com' #发件人的登陆用户名，默认和发件人地址一致
      smtp_auth_password: 'fjvfdgmpcbbd' #发件人的授权码
      smtp_require_tls: false
    
    templates:
      - '/usr/local/alertmanager/template/*.tmpl'
    
    route:
      group_by: ['alertname','cluster','service']
      group_wait: 5s
      group_interval: 5s
      repeat_interval: 2m
      receiver: 'default-receiver'
      
    receivers:
      - name: 'default-receiver'
        email_configs:
        - to: 'ylwang3@i163..com'
          html: '{
       { template "email.to.html" . }}' # 设定邮箱的内容模板

### 邮件模板 ###

{
       { define "email.to.html" }}
    {
       { range .Alerts }}
    =========start==========<br>
    告警程序: prometheus_alert<br>
