The Prometheus data model provides four core metrics: Counter: A value that increases, like a request or error count Gauge: Values that increase or decrease, like memory size Histogram: A sample of observations, like request duration or response size Summary: Similar to a histogram, but also provides the total count of observations. Seems like "up and down" is the most exact match for "increase and decrease", hence D
