Description

We currently offer the following messages/sec metrics:

1. Messages/sec per-container.
2. Messages/sec per-SystemStreamPartition for KafkaSystemConsumer.

We don't offer messages/sec per SystemStream. This metric is useful in cases you want to know the total messages processed for a stream in a single container, especially in cases where a single container is processing all partitions for a stream.
