SOLR-1855 has a script that checks replication details:
/solr/${CORE}/replication?command=details
# Get the last time the core replicated correctly.
# Get the last time the core failed to replicate.
# Is this core replicating (aka pulling index from master) right now?

Subject: replication start notification
Is there a programmatic way or otherwise to become aware when the
replication operation starts? In looking at the source for
ReplicationHandler, there aren't log statements to indicate that it started.
Thanks, Jon
