What's changed and what's your intention?
For back-pressure visualization in dashboard from the Prometheus data source, issue an instant query instead of a range query with a 30 min window, to fetch the real-time value of the recent 1 min.
Also remove the option for sampling algorithms as they're not applicable any more.
