Teiid really doesn't have its own dashboard, it uses its own developed tool to demonstrate how the dashboard could be used with datavirt. It uses http://dashbuilder.org/ Also, there's a newer version of the dashboard builder that you may want to take advantage of, with its new features.
I was talking indeed about teiid dashboard builder, https://github.com/teiid/teiid-dashboard which hasn't been updated for almost 2 years.
I would like to use newer versions of Teiid, and do a quick demo using dashboard builder, but between Teiid, teiid dashboard builder, and Teiid Designer I find myself having to use 8.12.5 to have them all working together.
I guess I could just download the newer version of dashbuilder and try to make it work with a newer version of Teiid
