How to check the client connected to which node in the cluster

Question

We want to check the client connections going to which server in the cluster. Is there any way to track it?

I saw some audit logs which has host files and source files.

host:FQDN/5.6.7.8|source:/1.2.3.4

Is this means the client from 1.2.3.4 ipaddress is connected to server 5.6.7.8 to run the query?

5.6.7.8 is the coordinator node here for this session?

Answer 1

Yes,

indeed. Your assumption is totally correct. When you take a look at the "CQL Logging examples" part in the Datastax' Cassandra documentation: http://www.datastax.com/docs/datastax_enterprise3.0/security/data_auditing

It explains that in your example 5.6.7.8 is the Cassandra node coordinating the requests from the client with IP 1.2.3.4.
