Reporting with AMS 5

We are exploring using AMS 5.  One of the reasons we are looking at this is that we can not multicast with our current media server.  After a month or so of trying to get multicast up and working we think we have solved that issue.  Now that it is running, is there a way we can track the number of connections we have for an event.  Currently we only do live webcasts a couple of times a month.  In the past I usually get asked for the number of people who watched the webcast.  This is within a corporate environment.  We are using Wirecast as our encoder if that matters.
