I just wndered in to the ALE section of the community so I'm sorry no one has responded to your post earlier.
ALE is only half of the equation for those cool dashboards.
ALE collects the data feeds from your Aruba ecosystem and then offers feeds to susbcribing analytic engines. I don't have the technical or marketing words for this, as I'm just starting to dabble in it myself.
ALE alone can provide almost nothing interesting, but the data streamed from it to an analytics platform can give you all manner of information.
