Create notification templates

Create reusable notification templates to send to your contact points.

You can add one or more templates to your notification template.

Your notification template name must be unique. You cannot have two templates with the same name in the same notification template or in different notification templates. Avoid defining templates with the same name as default templates, such as: __subject, __text_values_list, __text_alert_list, default.title and default.message.

In the Contact points tab, you can see a list of your notification templates.

To create a template, complete the following steps.

Click Add template.
Choose a name for the notification template.
Write the content of the template in the content field.
New notification template email.subject
Click Save.

{{ define "email.subject" }} and {{ end }} is automatically added to the start and end of the content:

Edit notification template email.subject

To create a notification template that contains more than one template:

Click Add Template.
Enter a name for the notification template.
Write each template in the Content field, including {{ define "name-of-template" }} and {{ end }} at the start and end of each template.
New notification template
Click Save.

Template the subject of an email

Template the subject of an email to contain the number of firing and resolved alerts:

1 firing alert(s), 0 resolved alerts(s)

Create a template called email.subject with the following content:

{{ define "email.subject" }}
{{ len .Alerts.Firing }} firing alert(s), {{ len .Alerts.Resolved }} resolved alert(s)
{{ end }}

Execute the template from the subject field in your contact point integration:
```
{{ template "email.subject" . }}
```

Template the message of an email

Template the message of an email to contain a summary of all firing and resolved alerts:

There are 2 firing alert(s), and 1 resolved alert(s)

Firing alerts:

- alertname=Test 1 grafana_folder=GrafanaCloud has value(s) B=1
- alertname=Test 2 grafana_folder=GrafanaCloud has value(s) B=2

Resolved alerts:

- alertname=Test 3 grafana_folder=GrafanaCloud has value(s) B=0

Create a notification template called email with two templates in the content: email.message_alert and email.message.

The email.message_alert template is used to print the labels and values for each firing and resolved alert while the email.message template contains the structure of the email.

{{- define "email.message_alert" -}}
{{- range .Labels.SortedPairs }}{{ .Name }}={{ .Value }} {{ end }} has value(s)
{{- range $k, $v := .Values }} {{ $k }}={{ $v }}{{ end }}
{{- end -}}

{{ define "email.message" }}
There are {{ len .Alerts.Firing }} firing alert(s), and {{ len .Alerts.Resolved }} resolved alert(s)

{{ if .Alerts.Firing -}}
Firing alerts:
{{- range .Alerts.Firing }}
- {{ template "email.message_alert" . }}
{{- end }}
{{- end }}

{{ if .Alerts.Resolved -}}
Resolved alerts:
{{- range .Alerts.Resolved }}
- {{ template "email.message_alert" . }}
{{- end }}
{{- end }}

{{ end }}

Execute the template from the message field in your contact point integration:
```
{{ template "email.message" . }}
```

Template the title of a Slack message

Template the title of a Slack message to contain the number of firing and resolved alerts:

1 firing alert(s), 0 resolved alerts(s)

Create a template called slack.title with the following content:

{{ define "slack.title" }}
{{ len .Alerts.Firing }} firing alert(s), {{ len .Alerts.Resolved }} resolved alert(s)
{{ end }}

Execute the template from the title field in your contact point integration:
```
{{ template "slack.title" . }}
```

Template the content of a Slack message

Template the content of a Slack message to contain a description of all firing and resolved alerts, including their labels, annotations, Silence URL and Dashboard URL:

1 firing alert(s):

[firing] Test1
Labels:
- alertname: Test1
- grafana_folder: GrafanaCloud
Annotations:
- description: This is a test alert
Silence: https://example.com/alerting/silence/new?alertmanager=grafana&matcher=alertname%3DTest1&matcher=grafana_folder%3DGrafanaCloud
Go to dashboard: https://example.com/d/dlhdLqF4z?orgId=1

1 resolved alert(s):

[firing] Test2
Labels:
- alertname: Test2
- grafana_folder: GrafanaCloud
Annotations:
- description: This is another test alert
Silence: https://example.com/alerting/silence/new?alertmanager=grafana&matcher=alertname%3DTest2&matcher=grafana_folder%3DGrafanaCloud
Go to dashboard: https://example.com/d/dlhdLqF4z?orgId=1

Create a template called slack with two templates in the content: slack.print_alert and slack.message.

The slack.print_alert template is used to print the labels, annotations, SilenceURL and DashboardURL while the slack.message template contains the structure of the notification.

{{ define "slack.print_alert" -}}
[{{.Status}}] {{ .Labels.alertname }}
Labels:
{{ range .Labels.SortedPairs -}}
- {{ .Name }}: {{ .Value }}
{{ end -}}
{{ if .Annotations -}}
Annotations:
{{ range .Annotations.SortedPairs -}}
- {{ .Name }}: {{ .Value }}
{{ end -}}
{{ end -}}
{{ if .SilenceURL -}}
  Silence: {{ .SilenceURL }}
{{ end -}}
{{ if .DashboardURL -}}
  Go to dashboard: {{ .DashboardURL }}
{{- end }}
{{- end }}

{{ define "slack.message" -}}
{{ if .Alerts.Firing -}}
{{ len .Alerts.Firing }} firing alert(s):
{{ range .Alerts.Firing }}
{{ template "slack.print_alert" . }}
{{ end -}}
{{ end }}
{{ if .Alerts.Resolved -}}
{{ len .Alerts.Resolved }} resolved alert(s):
{{ range .Alerts.Resolved }}
{{ template "slack.print_alert" .}}
{{ end -}}
{{ end }}
{{- end }}

Execute the template from the text body field in your contact point integration:
```
{{ template "slack.message" . }}
```

Template both email and Slack with shared templates

Instead of creating separate notification templates for email and Slack, you can share the same template.

For example, if you want to send an email with this subject and Slack message with this title:

1 firing alert(s), 0 resolved alerts(s)

Create a template called common.subject_title with the following content:

{{ define "common.subject_title" }}
{{ len .Alerts.Firing }} firing alert(s), {{ len .Alerts.Resolved }} resolved alert(s)
{{ end }}

For email, execute the template from the subject field in your email contact point integration:
```
{{ template "common.subject_title" . }}
```
For Slack, execute the template from the title field in your Slack contact point integration:
```
{{ template "common.subject_title" . }}
```
