That's just a matter of the PromQL query used to visualize the data. Try: (Q23_counter - Q23_counter offset 1m) >= 0
Another option is increase(Q23_counter[1m]), but since it interpolates the value over the time range given, it won't show values of exactly 1.0 On Thursday, 17 February 2022 at 00:10:16 UTC [email protected] wrote: > Hi Brian, > > Thank you very much for replying > > I meant push because I am using pushgateway in python prometheus client > > I will definitely consider counter for this > > But Out of 3 drifts - I want a spike in bar chart whenever a drift occurs > Like this > > > Regards, > Yegna > > > On Wed, Feb 16, 2022 at 12:37 Brian Candler <[email protected]> wrote: > >> It sounds like you're attacking this from the wrong direction. >> >> What I believe you want is a counter of drift events.
