Performance counter for Number of ports in use for making a connection

Question

I am using this command to identify the number of ports in use

netstat -anob

Is there a performance counter that i can use so that i can plot a graph on perfmon and see what happens when the number of requests per second increases?

Answer 1

Yes - you'll want to look at TCPv4/Connections Established. Note that this will be different than the IIS perf counters - not sure if you want system or IIS.
