Hi! We at Trackingplan.com (YC W22) do this. It's just an snippet you put in your site (you can install it using google tag manager) and automatically documents and monitors all your integrations schema and traffic wise.

It's a different approach than Metaplane, which we are actually evaluating for our dwh and backends monitoring. Trackingplan is more about creating trust on the data collection side of the problem.

Drop me a line, josele (at) trackingplan (dot) com if you want to know more!
