Despite being in the industry for 15 years, a decade of which at Amazon, I don't think I've ever seen an easier way to "keep your finger on the pulse" of your website or API endpoints. It's amazing that the Netflare found a way to do this completely unobtrusively.
A great product that auto tracks uptimes and degradation, and allows you to act before customers do... Its like your eyes on your application or site 24 /7. Highly recommended for any and all companies... best part is the cost... FREE!
