The above command it a great way to get a public website's "fingerprint", meaning a relatively quick way to sum up the entire site. I think I will add a database field for each website that I manage. This will allow a process to check the site's integrity, and ensure that everything is working. That, along with a link checker to ensure that all other resources load, will ensure the site's proper display.
