普罗米修斯警报管理员只发送邮件

Question

我有prometheus alertmanager和简单规则

普罗米修斯

• 作业名称："主机_PRO"；static_configs:

  • 目标：["192.168.0.17:9100"]标签：组："alert">

• 作业名称："主机_ PRE"；static_configs:

  • 目标：["10.2.2.235:9100"]标签：组："noalert"名称："PVE">

alertmanager.yml

global:
# The smarthost and SMTP sender used for mail notifications.
smtp_smarthost: 'example:587'
smtp_from: 'example'
smtp_auth_username: 'example'
smtp_auth_password: 'example'
smtp_require_tls: true
route:
group_by: ['alertname']
group_wait: 10s
group_interval: 10s
repeat_interval: 24h
routes:
- match:
group: alert 
receiver: mail
receivers:
- name: 'mail'
email_configs:
- to: '[e-mail]'

规则示例

- alert: NodeCPU_0_High
expr: 100 - (avg by(instance, cpu) (irate(node_cpu_seconds_total{mode="idle", cpu="0"}[1m])) * 100) > 80
for: 2m
labels:
severity: critical
app_type: linux
category: cpu
annotations:
summary: "Node CPU_0 usage is HIGH"
description: "CPU_0 load for instance {{ $labels.instance }} has reached {{ $value }}%"

如何发送电子邮件只有当主机与组"；警报"；是高吗？

Answer 1

在alertmanager.yml文件中设置以下内容：

route:
...
routes:
- receiver: none
matchers:
- group != alert
- receiver: mail
matchers:
- group = alert 
receivers:
- name: none
- name: 'mail'
email_configs:
- to: '[e-mail]'
