What do you mean by saying "correctly replicated"? Keep in mind by using
LOCAL_QUORUM, you should *not* expect the data to be strongly consistent
when the read and write are in different DCs. If that's desired, use
EACH_QUORUM on either read or write, and keep the other at LOCAL_QUORUM.

Hello Team,
I have a multi dc Cassandra setup.
We write and read using local quorum to a particular datacenter A
The replica definition in schema is correct.
Sometimes we don't see data getting correctly replicated to datacenter B.
I need to know what may be different ways to troubleshoot this.
What are the key metrics, details, log patterns I may look for
Thanks
