avg() doesn't deal with NaN's

[zemek]

If you try to run avg(query) on a query that returns some NaN values, the entire avg is NaN.

It seems like it would be reasonable to just exclude these NaNs from the average so you don't have to do like avg(query >= 0) or something more complicated if you want both positive/negative numbers.

and if you wanted to create an alert if query has NaN values, you would need to write a separate alert anyway like query != query

This is the correct behaviour. You are most likely aggregating incorrectly and trying to take an average of an average, which is statistically invalid.

It makes more sense to ask questions like this on the prometheus-users mailing list rather than in a GitHub issue. On the mailing list, more people are available to potentially respond to your question, and the whole community can benefit from the answers provided.
