• 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.
