This could be two questions with different answers:


1. Is there anyone / who is connected to the Cassandra server right now?

Use the netstat or ss command and check the active TCP connections on 
native port (default is 9042)


2. Is there anyone / who is connecting to the Cassandra servers between 
now and next hour/day/week/month/etc.?

Use iptables/nftables to log new TCP connections (ct state new) on that port
