      修改 alertmanager.yml 配置邮件报警对象

      [root@localhost alertmanager]# cat alertmanager.yml

      global:

      resolve_timeout: 5m

      smtp_smarthost: 'smtp.163.com:25'

      # group_by: ['alertname']

      group_wait: 10s

      group_interval: 1m

      repeat_interval: 1m

      receiver: 'jsb'

      receivers:

      - name: 'jsb'

      email_configs:

      - to: "TARGET_ADDRESS@163.com"

      # 使用 alertmanager 自带的 amtool 工具检查一下alertmanager.yml 配置文件书写是否正确  郑州不孕不育医院哪家好http://byby.zztjyy.com/

      description: "{{ $labels.instance }} of job {{ $labels.job }} yi shutdown 1 minutes"

      expr: avgBusy1 > 60

      for: 1m

      labels:

      severity: warning

      # 使用 promtool 检查配置文件书写是否正确,然后重启 prometheus

      [root@e36188d4c068 prometheus]# ./promtool check config prometheus.yml

      Checking prometheus.yml

      SUCCESS: 2 rule files found

      Checking rules/cpu.rules

      SUCCESS: 1 rules found

      Checking rules/test.rules

      SUCCESS: 1 rules found

      [root@e36188d4c068 prometheus]# systemctl restart prometheus

      测试邮件报警

      我们这正常的交换机 cpu 使用率是 35% 左右,会有一点浮动,但是基本上就是这样,通过修改 rules/cpu.rules 中的阈值,进行触发邮件报警;

      expr: avgBusy1 > 30
