How to use Grafana Alerts with the Telegram

Grafana Alert Template.md

• Template name: telegram.message

• Content:

  {{ define "alert_list" }}{{ range . }}{{ .Labels.alertname }}
  {{ range .Annotations.SortedPairs }}<strong>{{ .Name }}</strong>: {{ .Value }}
  {{ end }}| {{ if gt (len .GeneratorURL) 0 }}<a href="{{ .GeneratorURL }}">source</a> | {{ end }}{{ if gt (len .SilenceURL) 0 }}<a href="{{ .SilenceURL }}">silence</a> | {{ end }}{{ if gt (len .DashboardURL) 0 }}<a href="{{ .DashboardURL }}">dashboard</a> | {{ end }}{{ if gt (len .PanelURL) 0 }}<a href="{{ .PanelURL }}">panel</a> |{{ end }}
  —
  {{ end }}{{ end }}
  {{ define "telegram.message" }}
  {{ if gt (len .Alerts.Firing) 0 }}<strong>FIRING!!!</strong>
  —
  {{ template "alert_list" .Alerts.Firing }}
  {{ if gt (len .Alerts.Resolved) 0 }}
  {{ end }}{{ end }}{{ if gt (len .Alerts.Resolved) 0 }}<strong>Resolved</strong>
  —
  {{ template "alert_list" .Alerts.Resolved }}
  {{ end }}{{ end }}
  

• Contact point | Optional Telegram settings | Message: {{ template "telegram.message" . }}

• Add verbose annotations to your alerts. Example: The <code>{{ $labels.host }}</code> host is low on free space! Used: {{ $values.display.Value }}% (where display is one of the queries).

• I usually add the following queries: data (the datasource query), metric (the reduce expression), condition, and display, which is round($metric). Multi-dimensional rules documentation.

Also, check out this fork by @gelldur, this templeate is much more cmprehensive.

Helps a lot!
When I was learning how to write message templates, it was much better to read this template than to read the documentation directly.

Thanks you I managed to find the soruce code and create my own custom alerts ✨

{{/* Plantilla Telegram */}}
{{ define "alertas" -}}
{{ range . }}
{{ if len .Values -}}
Values:
{{- range $refID, $value := .Values -}}
    - {{ $refID }} = {{ $value }}
{{ end -}}
{{ end -}}
{{ if len .Labels.SortedPairs }}
Labels:
{{ range .Labels.SortedPairs -}}
    - {{ .Name }} = {{ .Value }}
{{ end -}}
{{ end -}}
{{ if len .Annotations.SortedPairs }}
Annotations:
{{ range .Annotations.SortedPairs -}}
    - {{ .Name }} = {{ .Value }}
{{ end -}}
{{ end -}}
{{ end -}} {{/* range */}}
{{ end -}} {{/* define alertas */}}

{{ define "plantilla.message" }}
{{ if gt (len .Alerts.Firing) 0 }}
🚨 FIRING!!!
{{- template "alertas" .Alerts.Firing -}}
{{ end -}}
{{ if gt (len .Alerts.Resolved) 0 }}
✅ RESOLVED!
{{- template "alertas" .Alerts.Resolved -}}
{{ end -}}
<a href="192.168.0.11:3000">Dashboard</a>
{{ end }}

@gelldur can you make a tutorial to how to use telegram notification template?

Hello @Himura2la
Is it possible to include the server in value parameter of solved? The empty value will make ambuigty to identify which system have been solved.
Another question is, is it possible to change summary of solved? For now in both cases (firing and solved) it uses the same summary.

Hey guys, hello @Himura2la, thank you so much. Please help a little bit. How to really use this template? How to add here the value i want to monitor? from my expression
