Versions:
- Grafana: 7.4.0+
- Prometheus: 2.24.1+
- Node Exporter: 1.0.1+
Interval and range variables: http://docs.grafana.org/features/datasources/prometheus/
- Support for $__range, $__range_s and $__range_ms only available from Grafana v5.3
- It’s possible to use some global built-in variables in query variables; $__interval, $__interval_ms, $__range, $__range_s and $__range_ms, see Global built-in variables for more information. These can be convenient to use in conjunction with the query_result function when you need to filter variable queries since label_values function doesn’t support queries.
- Make sure to set the variable’s refresh trigger to be On Time Range Change to get the correct instances when changing the time range on the dashboard.
