Prometheus 绑定QQ邮箱告警

环境准备：

1.部署好Prometheus，可参考https://blog.51cto.com/u_13760351/5513690

2.为了方便实验，只用了一台服务器（192.168.10.15），生产环境可以分开部署

部署过程：

1.编辑alertmanager.yml

vim alertmanager.yml

global:
  resolve_timeout: 5m
  smtp_from: '[email protected]'            #发送人的邮箱，自定义
  smtp_smarthost: 'smtp.qq.com:465'
  smtp_auth_username: '[email protected]'  #你自己的邮箱
  smtp_auth_password: '安全码'   #这个是上面获取安全码的值，不是你邮箱的密码
  smtp_require_tls: false
  smtp_hello: 'qq.com'

route:
  group_by: ['alertname']
  group_wait: 5s
  group_interval: 5s
  repeat_interval: 5m
  receiver: 'email'

receivers:
- name: 'email'
  email_configs:
  - to: '[email protected]'      #收件人
    send_resolved: true
           

2.部署alertmanager服务

docker run -d --privileged=true \
--restart=always \
-p 9093:9093 \
-v /root/prometheus/alertmanager.yml:/etc/alertmanager/alertmanager.yml \
-v /etc/localtime:/etc/localtime:ro \
--name alertmanager \
quay.io/prometheus/alertmanager:latest
           

3.编写告警规则

vim host_monitor.yml

groups:
- name: node-up
  rules:
  - alert: node-up
    expr: up == 0
    for: 5s  #服务停止超过5秒就会告警停止
    labels:
      team: node
    annotations:
      summary: "{{$labels.instance}}  Instance has been down for more than 5 seconds"
           

4.添加告警

vim prometheus.yml

global:
  scrape_interval:     15s
  evaluation_interval: 15s
alerting:
  alertmanagers:
  - static_configs:
    - targets:
       - 192.168.10.15:9093 #替换为当前主机ip
rule_files:
  - "/etc/prometheus/host_monitor.yml"  #规则路径

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
    - targets: ['localhost:9090']

  - job_name: 'node'
    file_sd_configs:
      - files:
        - node_targets.yml

  - job_name: 'mysql'
    static_configs:
    - targets: ['192.168.10.15:9104']

           

手动停止node服务，测试告警

5.查看服务状态

6.查看告警规则

7.服务故障，邮件通知

8.服务恢复，邮件通知
