Sum
A delta sum over the collection interval, not a running total, because backends such as CloudWatch already aggregate within each period - a cumulative counter at 100 would publish 100 every minute and sum to 6000 over an idle hour. This differs from OpenTelemetry's default temporality.
Parameters
value
the delta. May be negative when monotonic is false.
monotonic
true for MonotonicCounter, false for UpDownCounter, for exporters that distinguish the two.
