hi there,

The post is about selecting a top level metric for monitoring website performance. One a problem is indicated, you would definitely need to drill in to figure out what part of your app is affected, when, and what caused it.

LeanSentry (our own application monitoring product, https://www.leansentry.com) does this. However, describing this was outside the scope of my post (but you can see the demo of it on the website).
