你好，我想歸零.Alerts.Firing，這也是$alert在迭代之后。我是golang的新手，請幫忙，謝謝。
補充：其實是一個Prometheusalert的模板。原始日期由（微信）創建alertmanager并發送至receiver（微信）。這是微信模板
{{ define "wechat.default.message" }}
{{- if gt (len .Alerts.Firing) 0 -}}
{{- range $index, $alert := .Alerts.Firing -}}
{{- if eq $index 0 -}}
Detail: {{ $alert.Labels.alertname }}
{{- end }}
---- Problem started ------
Message: {{ $alert.Annotations.description }}
Time: {{ ($alert.StartsAt.Add 28800e9).Format "2006-01-02 15:04:05" }}
{{ if gt (len $alert.Labels.instance) 0 }}ip: {{ $alert.Labels.instance }};{{- end }}
{{- if gt (len $alert.Labels.namespace) 0 }}namespace: {{ $alert.Labels.namespace }};{{- end }}
{{- if gt (len $alert.Labels.node) 0 }}Node: {{ $alert.Labels.node }};{{- end }}
{{- if gt (len $alert.Labels.pod_name) 0 }}Pod: {{ $alert.Labels.pod_name }}{{- end }}
-----------------
{{ $alert :="" }}
{{- end }}
{{- end }}
{{- if gt (len .Alerts.Resolved) 0 -}}
{{- range $index, $alert := .Alerts.Resolved -}}
{{- if eq $index 0 }}
!!!! Problem resolved !!!!!
Detail: {{ $alert.Labels.alertname }}
{{- end }}
Started_at: {{ ($alert.StartsAt.Add 28800e9).Format "2006-01-02 15:04:05" }}
Resolved_at: {{ ($alert.StartsAt.Add 28800e9).Format "2006-01-02 15:04:05" }}
-------
{{ if gt (len $alert.Labels.instance) 0 -}}ip: {{ $alert.Labels.instance }};{{- end }}
{{- if gt (len $alert.Labels.namespace) 0 -}}namespace: {{ $alert.Labels.namespace }};{{- end }}
{{- if gt (len $alert.Labels.node) 0 -}}Node: {{ $alert.Labels.node }};{{- end }}
{{- if gt (len $alert.Labels.pod_name) 0 -}}Pod: {{ $alert.Labels.pod_name }}{{- end }}
{{ $alert :="" }}
-----------------
{{- end }}
{{- end }}
{{- end }}
所以很難看到alertmanager. 我只能看到這個模板呈現的結果。請看下文。

uj5u.com熱心網友回復：
只是意識到它不能通過零一個物件來解決。因為：
- 無法在微信中保留最后一個“已解決”的主機 232.20。
- 下次原始資料仍然包含“已決議”的主機 232.20，因此無法通過任何方式將其洗掉。
- 所以輸出也不能改變。
謝謝。
