AWR report is a good starting point. x$ksxp_client / dba_hist_ic_client_stats / dba_hist_ic_device_stats are some of the views that you can query to get interconnect traffic at client/device level.

But, you really have to start in AWR report to understand global cache workload. Then decide if your interconnect hardware is handling the traffic well or not. Since PQ workload is captured in x$ksxp_client from 11g onwards, you could use dba_hist_ic_client_stats view to differentiate workload at client level.

Of course, at OS level, netstat can be used. In Solaris, I like the script netstatMulti in this page:
