Suppose I have a counter metric; let's name it `foo`. Suppose foo first shows up with a value of 0 in a scrape at time t0, shows up with a value of 10 in a scrape at time t0+10s, and has value 10 in all subsequent scrapes. What will the PromQL expression `rate(foo[60s])` get me? I suppose nothing until time t0+60s; some non-zero value from t0+60s to t0+70s; and zero from t0+70s onward. Is that right? If not, what will I get?
Now suppose instead that foo first shows up in a scrape at time t0 with a value of 10, and in every scrape after that the value of foo is also 10. What will `rate(foo[60s])` give me? If I understand correctly, it will give me nothing until time t0+60s, and from then on it will give me zero. Have I got this right? That is a rather disappointing answer. This counter really did start at zero, and got 10 increments before the first scrape. It would be gratifying to have a PromQL query that shows this blip of activity. Can I write a different PromQL query that will get this result? While retaining all the other smarts of `rate`?
