- 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](https://grafana.com/docs/grafana/next/alerting/alerting-rules/create-grafana-managed-rule).
