I did. And I see the words "A human just has to parse through a few lines of text ...".

Why is a human doing this? Why isn't the tool identifying the cause through a pre-determined dependency tree and only alerting on the salient points instead of relying on a human intelligently parsing through this data when they've been woken up by a page at 3am?

My experience has shown me that this kind of parsing can be avoided by using the right tools.

Of course if the system can automatically detect the problem and fix it then it should (this is also mentioned somewhere in the document). But at some point it will have to bail and then a human has to have a look.
