> {code}
> Samza counter "messages-chosen" is registered per system stream without identifying by partition or source. It must include partition or only include the system so the metric name can be unique under all scenarios.

>   systemStreamMessagesChosen += systemStream -> newCounter("%s-%s-messages-chosen" format (systemStream.getSystem, systemStream.getStream))
