Template data

Template data is passed on to [message templates]({{< relref "./_index.md" >}}) as well as sent as payload to webhook pushes.

Name	Type	Notes
Receiver	string	Name of the contact point that the notification is being sent to.
Status	string	firing if at least one alert is firing, otherwise resolved.
Alerts	Alert	List of alert objects that are included in this notification (see below).

CommonAnnotations	KeyValue	Annotations common to all the alerts included in this notification.
ExternalURL	string	Back link to the Grafana that sent the notification. If using external Alertmanager, back link to this Alertmanager.

The Alerts type exposes functions for filtering alerts:

• Alerts.Firing returns a list of firing alerts.
• Alerts.Resolved returns a list of resolved alerts.

KeyValue

KeyValue is a set of key/value string pairs that represent labels and annotations.

Here is an example containing two annotations:

{
  "summary": "alert summary",
  "description": "alert description"
}

In addition to direct access of data (labels and annotations) stored as KeyValue, there are also methods for sorting, removing and transforming.

SortedPairs		Sorted list of key & value string pairs
Remove	[]string	KeyValue	Returns a copy of the Key/Value map without the given keys.
Names		[]string	List of label names
