vector cannot contain metrics with the same labelset

[li yun]

I execute the following query

label_replace(sum_over_time(augmento{coins="xxx"}[20m]), "instance", "", "", "")

Got the following error：

vector cannot contain metrics with the same labelset

What am I doing wrong? thank you very much for your help

Hi,

Looks like the attempted removal of the instance label would lead to
multiple results with the same label combinations, which isn't allowed.

What are you trying to do?
What do your results look like without the label_replace call?

Maybe you are looking for some aggregation function (min, max, avg, topk)?

Kind regards,
Christian

Hi,

You probably want:

sum without(instance) sum_over_time(augmento{coins="xxx"}[20m])

Yes, I want to remove the instance, I tried sum without(instance) sum_over_time(augmento{coins="xxx"}[20m]), but there was an error

{"status":"error","errorType":"bad_data","error":"parse error at char 24: unexpected identifier \"sum_over_time\" in aggregation, expected \"(\""}

sum without(instance) (sum_over_time(augmento{coins="xxx"}[20m])
