prometheusalert区分告警到不同钉钉群-Toy模板网

这篇具有很好参考价值的文章主要介绍了prometheusalert区分告警到不同钉钉群。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

方法一

修改告警规则

- alert: cpu使用率大于88%
    expr: instance:node_cpu_utilization:ratio * 100 > 88
    for: 5m
    labels:
      severity: critical
      level: 3
      kind: CpuUsage
    annotations:
      summary: "cpu使用率大于85%"
      description: "主机 {{ $labels.hostname }} 的cpu使用率为 {{ $value | humanize }}"

根据Kind区分，规则一kind1，规则二是kind2。

alertmanager配置示例

global:
  resolve_timeout: 5m
  smtp_from: from@email.com
  smtp_smarthost: smtp.net:port
  smtp_auth_username: from@email.com
  smtp_auth_password: PASS
  smtp_require_tls: false
route:
  receiver: 'email'
  group_by: ['alertname']
  group_wait: 10s
  group_interval: 10s
  repeat_interval: 10m
  routes:
  - receiver: 'our'
    group_wait: 10s
    match_re:
       severity: warning
  - receiver: 'other'
    group_wait: 10s
    match_re:
       severity: busi

templates:
  - '*.html'
receivers:
- name: 'email'
  email_configs:
  - to: 'xuxd@email.com'
    send_resolved: false
    html: '{{ template "default-monitor.html" . }}'
    headers: { Subject: "[WARN] 报警邮件" } #邮件主题
- name: 'our'
  webhook_configs:
  - url: http://127.0.0.1:8060/dingtalk/our/send
- name: 'other'
  webhook_configs:
  - url: http://127.0.0.1:8060/dingtalk/other/send

route:除了email这个全局配置的接收者外，下面的routes指定了两个特定的接收者，一个接收者叫“our”，匹配warning级别的；另一个叫“other”，匹配busi级别的，这两个级别在最前面的规则里定义，不是什么特定关键字，就是自己随便定义的一个标记
receivers:这里指定了上面定义的接收者的配置，email指定邮件发给谁；“our”指定dingtalk的发送url，注意这个uri的末尾，send前用的"our";“other”下面指定了两个url，区别就是url末尾的send前面，一个是“our”，另一个是"other"

prometheus-webhook-dingtalk配置

## Customizable templates path
templates:
   - /home/user/monitor/alert/prometheus-webhook-dingtalk-1.4.0.linux-amd64/template/template.tmpl

## Targets, previously was known as "profiles"
targets:
  our:
    url: https://oapi.dingtalk.com/robot/send?access_token=xxxx
    secret: xxx_secret
  other:
    url: https://oapi.dingtalk.com/robot/send?access_token=xxx_other
    secret: xxx_other_secret

targets下有两个，分别是"our"和"other",这里对应上面alertmanager配置的url里的"our"和"other。

这样配置，如果规则一告警，就是alertmanager的name为other的receiver来发送告警通知，发送到我们的钉钉群和业务侧钉钉群。如果是规则二告警，通过our发送，便只发送到我们的钉钉群。
