Prometheus（普罗米修斯）搭建监控在我的上一篇博客，如果有需要可以去参考参考，这篇时下篇，上篇是Prometheus（普罗米修斯）搭建监控，两篇可以连起来看

温馨提示，请将下文文档中所涉及到的邮箱，换成你们自己的。谢谢，不然你们接收不到报警信息，会发到我这
1）部署prometheus监控组件alertmanager.

[root@docker01 ~]# docker load < alertmanager.tar
[root@docker01 ~]# docker run -d --name alertmanager -p 9093:9093 prom/alertmanager
[root@docker01 ~]# vim alertmanager.yml
global:
resolve_timeout: 5m
smtp_from: '2389113325@qq.com'
smtp_smarthost: 'smtp.qq.com:465'
smtp_auth_username: '2389113325@qq.com'
smtp_auth_password: 'ikeamxidxbodeaba'
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: '2389113325@qq.com'
    send_resolved: true
    inhibit_rules:
  • source_match:
    severity: 'critical'
    target_match:
    severity: 'warning'
    equal: ['alertname', 'dev', 'instance']
    [root@docker01 ~]# docker rm -f alertmanager
    [root@docker01 ~]# docker run -d --name alertmanager -p 9093:9093 -v /root/alertmanager.yml:/etc/alertmanager/alertmanager.yml prom/alertmanager

2）创建监控规则，使用email报警方式。监控服务运行状态，如果服务节点down机状态，则发送邮件。
[root@docker01 ~]# mkdir -p prometheus/rules
[root@docker01 ~]# cd prometheus/rules/

[root@docker01 ~]# vim prometheus.yml
12行：

12行：

• targets:
  • 192.168.1.10:9093

15行：

• "/usr/local/prometheus/rules/*.rules"

[root@docker01 ~]# docker rm -f prometheus
[root@docker01 ~]# docker run -d -p 9090:9090 --name prometheus --net=host -v /root/prometheus.yml:/etc/prometheus/prometheus.yml -v /root/prometheus/rules/node-up.rules:/usr/local/prometheus/rules/node-up.rules prom/prometheus

Docker02:
[root@docker02 ~]# docker stop cadvisor
Cadvisor

3）创建邮件发送模板，仍使用email报警方式，模拟服务节点down机状态，查看验证email发送模板。
[root@docker01 ~]# cd prometheus/
[root@docker01 prometheus]# mkdir alertmanager-tmpl
[root@docker01 prometheus]# cd alertmanager-tmpl/

[root@docker01 alertmanager-tmpl]# vim email.tmpl
{{ define "email.from" }}2389113325@qq.com{{ end }}
{{ define "email.to" }}2389113325@qq.com{{ end }}
{{ define "email.to.html" }}
{{ range .Alerts }}

{{ end }}
{{ end }}
[root@docker01 ~]# vim alertmanager.yml

8行：
templates:

• '/etc/alertmanager-tmpl/*.tmpl'
  21行：
  
  21行：
• to: '{{ template "email.to"}}'
  html: '{{template "email.to.html" .}}'
  [root@docker01 ~]# docker rm -f alertmanager
  [root@docker01 ~]# docker run -itd --name alertmanager -p 9093:9093 -v /root/alertmanager.yml:/etc/alertmanager/alertmanager.yml -v /root/prometheus/alertmanager-tmpl:/etc/alertmanager-tmpl prom/alertmanager:latest

Docker02:
[root@docker02 ~]# docker stop cadvisor
