Replication 201 - work was performed, the stream was replicated to the target cluster.
Replication 409 - the stream is already present the target cluster.
Duplicate - the stream has already been sent to the replication feed so not sent again.
Obsolete - the stream has been deleted during the time in the feed queue or the stream may have been trimmed while in the queue (from retires or relocation). This is likely not helpful as it exposes intra-cluster activities and not SCSP operations the application starts.
The ratio of real work in the above example is:
28226 / 577463
Obtain a real rate of streams replicated by taking the rate from a single node an hour apart and performing the math:
