This is great!
A lot of companies think of using Looker to report on the usual suspects: revenue, user growth etc. and only for only a couple departments within a company. However, this really shows how you can use Looker beyond the usual use cases. Go setup a Looker alert for ETL load errors.
One note: On row 284 of the view, you have value_format_name which is not something I am seeing in any of the openly available Looker versions. Looks like it is in learn.looker.com so I am sure the general public will have access to it soon.
