which backend are you using? this potentially may be a bug where we're

I have also verified the samples query for this meter and there are 1544 samples (output shown below) with all of them having value as "150.0". So ideally the "Avg" filed should be "150.0" in this scenario. Could anyone tell me in what scenario we will see these two fields as "inf" in the meter statistics query? Plz let me know if you need more details or logs here. Appreciate your help.
