Hi List,

How do you measure the network traffic going on your RAC interconnect? on the Oracle and OS side...

Can you share the efficient tools that you use?

I'm trying to figure out (aside from the GC wait events popping out on the AWR)... how would you know if your interconnect is congested?

Let's say I had some RAC node evictions, I want to measure if it's really the interconnect that is congested (I'm looking for the numbers).. the same way that I'll be looking on the CPU scheduling and disk IO issues...
