2）創建監控規則，使用email報警方式。監控服務運行狀態，如果服務節點down機狀態，則發送郵件。
[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）創建郵件發送模板，仍使用email報警方式，模擬服務節點down機狀態，查看驗證email發送模板。
[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 }}
