GrafanaCONline: Prometheus rate queries in Grafana
Why Stack Overflow recommends it
Stack Overflow users link it when explaining how Grafana's time interval relates to the range duration in Prometheus rate and increase queries.

What it is
A GrafanaCONline 2020 session on choosing the range in Prometheus rate queries when they are visualized in Grafana. It covers dynamic range variables, the many interval settings, interactions with recording rules, and a new Prometheus data source feature meant to improve rate graphs.

You will never get the exact increase in each of the time windows due to the way Prometheus rate and increase work. By setting the min step in Grafana to whatever window step you like and the range selection in the query itself to $__interval and $__rate_interval once Grafana 7.2 is released, you get pretty close to what you want. But consider that once you zoom out far enough the window will start to grow if there are not enough pixels to fit all "windows". In addition having the min step and range exactly the same can and will lead to increases getting lost. $__rate_interval fixes that. Edit: The queries from Grafana to Prometheus contains a step parameter that Prometheus "steps through" a

I had similar question when I started learning Prometheus. First thing to note, Prometheus expression language evaluates to four types . strings scalars instant vectors range vectors ( Instant vectors vs range vectors is very well explained in the resources I have linked below. ) Prometheus HTTP API's [LINK] have two types , instant queries - API returns single value for the given evaluation time range queries - API returns multiple values based on time range and step When querying through the Prometheus UI, results can be represented as either table or graph . If you inspect the API call made from the Prometheus UI, you will notice that queries displaying data in the table will hit the inst
