Err... You seem to be disagreeing with the example case rather than
this particular statement. I wholeheartedly agree with you that it's
far better to check the underlying services than just the end product,
but it still usually doesn't make sense to have all of those services
being parents to the "ultimate" check, and it certainly doesn't make
sense to have the "ultimate" service check be a child of just one such
component that makes up the entire web-service (or whatever it might
be).

An exercise in futility. Teach them regex-fu instead and refuse to add
CSS tags until they've made their logmessages regex-searchable in some
sane way.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
