The unit for this metric is `{operation}`, reflecting that there is no 1-1 map between this throttle state and a connection. The current Prometheus value can be extracted by subtracting the `throttled` counter from the `unthrottled` one. This can prove insufficient to debug issues, as many connections can be throttled and unthrottled in between metric collection runs, so emitting just the delta is not enough. Same applies for pause/resume attributes, of course. -- This is an automated message from the Apache Git Service.
