So, sure I understand the attraction of an active notification. But, for that to
work that assumes people actively looking at things and taking action as soon as
they get an email. That very rarely happens, even for people who look at the
failures regularly. Let's take a look at the stable maint list:


That's 2 months, where is the immediate response on those? Only a handful only
have a single isolated failure, and looking at them they are mostly transient
failure (like a down mirror, git failure, upstream release, etc) which was
likely blocking other development and was almost certainly fixed without looking
at the ML results. The majority of the failure just sat for a long time.

The issue with the ML is that it's not actually used as a notification but
instead people only look at the details periodically. The ML provides a really
bad interface for visualizing these results over time. That's why using
openstack-health is a better solution for doing this. Now, I don't pretend that
it's complete or perfect, it's still a relatively young project. But, the thing
is everyone can help us work on fixing any issues or gaps with it:


Instead, of pretending the ML work for doing this I think it'll be better if we
concentrate on making the dashboard for this better.
