.NET monitoring the number of concurrent connections
===

I've seen a variety of resources on the web recommending that if I have an app making lots of web service calls, to modify the web.config with a section like this:

    <system.net>
        <connectionManagement>
          <add address="*" maxconnection="40" />
        </connectionManagement>
      </system.net>

Is there a way with Windows or SysInternals tools to monitor/log the currently used connections to see if this really is a problem?
