You can customize alarm templates

  • Creating a template File
[root@prometheus ~]# mkdir -p /usr/local/Prometheus_alertmanager/template [root@prometheus ~]# vim /usr/local/Prometheus_alertmanager/template/email.tmpl {{ define "email.html" }} {{ range .Alerts }} <pre> = = = = = = = = start = = = = = = = = = = alarm procedures: prometheus_alert alarm levels: {{. Labels. The severity}} the alarm types: {{. Labels. Alertname}} fault host: {{.identifiers. Instance}} Alarm subject: {{.identifiers. Summary}} Alarm details: {{.Identifiers. {{ (.StartsAt.Add 28800e9).Format "2006-01-02 15:04:05" }} ========end========== </pre> {{ end }} {{ end }}Copy the code

Format “2006-01-02 15:04:05” must not be filled in, the time defined here is the birth time of go language!! If you fill in the wrong time, it will be garbled.
