Template variables for alerting rule labels and annotations

The following template variables are available when expanding annotations and labels.

Name	Description
$labels	The labels from the query or condition. For example, {{ $labels.instance }} and {{ $labels.job }}. This is unavailable when the rule uses a [classic condition]({{< relref "../../alerting-rules/create-grafana-managed-rule/#single-and-multi-dimensional-rule" >}}).
$values	The values of all reduce and math expressions that were evaluated for this alert rule. For example, {{ $values.A }}, {{ $values.A.Labels }} and {{ $values.A.Value }} where A is the refID of the expression. If the rule uses classic conditions, then a combination of the refID and position of the condition is used. For example, {{ $values.A0.Value }} or {{ $values.A1.Value }}. If a value can return no data then it is recommended to use either {{ $values.A }} where the missing value will show <no value> or an if statement to check if A exists when using {{ $values.A.Labels }} and {{ $values.A.Value }}. For example, {{ if $values.A }}{{ $values.A.Value }}{{ end }}.
$value	The value string of the alert instance. For example, [ var='A' labels={instance=foo} value=10 ].
