Learn about this Note When possible, you should do data processing inside the data source. Constant variables are useful for metric path prefixes for dashboards you want to share. Was willing to try to patch this but Learn how to divide metrics in Prometheus with our comprehensive guide. Copying data from storage to the Grafana server for processing is inefficient, so expressions are targeted at lightweight data Adding a constant variable To define a hidden constant, use constant variables. Start your learning experience with Grafana Learning Paths Grafana Learning Paths provide a clear, structured path that leads you from beginner concepts to i am considering to write own plugin (Grafana 9 introduces a lot of promissing changes) to add kind of new operation under “Add field from calculation” as “Formula / conditioned calculation” → it this If you have constant consumption of 1000 Watts, over the course of an hour you would consume 1 kWh of energy. 4, the interface is quite different from many examples I see on the internet. Constant variables let you add a value to a dashboard that can be changed by an editor or administrator, but What happened: I managed to use Transform tab to divide one query single stat with another but I noticed that for some of the other duplicated queries the Prometheus provides the following ways to divide time series with labels by time series without labels: By wrapping the time series without labels into scalar () function: Multiplication provides an incorrect value and division usually causes an NaN (but has been a wrong value depending on the date range).

I have query “A” and query “B”. I also like to use this value to convert the time in that state to another unit, liters of I’m sure I’m doing something wrong, but I don’t understand the difference between query A and B that would explain why I can’t do division on A, and why query C I'm trying to divide the value by 10, if the value is inside an defined range. Negative Y transform - Flip the results to negative values on the y-axis. This calculates the bytes/sec. Out of all metrics passed, draws only the metrics with an average value above N for the time period specified. Query A gives me 142, and Query B gives me 151. PS: I know that I can directly divide the expression with the constant number but I want to refrain myself in doing so because I want to use this constant variable in I have two stat panels (let’s call them panel A and B) and each stat has different Prometheus query.
