I'm feeling a bit Gauged about this question. But I'm sure I'll nail it when I'm not so Prometheus-ed.

A) Gauge is the way to go here. It's the one that's designed to handle dynamic values, unlike those other static metrics.

B) I agree, Gauge is perfect for tracking values that can change over time.

Hmm, I was thinking B) Histogram, because that can show the distribution of values. But I guess that's not the best fit for a single number that fluctuates.

I'm going to go with D) Counter, because that's the one that keeps track of a value that can only increase over time, right?

No problem! It can be a bit confusing, but now you know that Gauge is the metric type that can increase and decrease over time.

I see, thanks for the clarification. I thought it was Counter because it keeps track of values that can only increase.

Actually, the correct answer is A) Gauge. A Gauge represents a single number value that can increase and decrease over time.

Actually, a Counter is a cumulative metric that can only increase, while a Gauge can increase and decrease.

I'm not sure, but I think it's D) Counter because it counts occurrences.

A Gauge sounds like the perfect choice to represent a number that can go up and down. The other options seem more for counting or binning data.

Yeah, a Gauge makes sense for that type of metric. Counters are more for incrementing values and histograms are for distribution data.
