I agree with your point that users many not know when something isn't =
working right or not understand the significance of something they =
observe. I have visited users on site and watched as they clicked =
through warnings, exceptions and errors without comment to get to the =
problem that is really bugging them. So yes, people do ignore obvious =
problems if the pain is tolerable. But my approach would be to engage =
my users rather than try instrument the database in such a way that =
would reduce my dependence on prompt disclosure of issues from my users. =
You haven't said anything I disagree with but, personally, I have more =
confidence in my ability to extract the details of my users experience =
through communication and observation than setting up a health check. =
I'm in a position to do that with my users though and I'm sure many =
DBA's don't have that kind of contact.

Just because no-one is complaining (that you know about) does not mean=20

If we use the analogy of a health check in the medical fashion, we need =
to consider the difference between reactive and preventative actions.=20
When we have pain, illness or something just does not feel right, we are =
being reactive. We can describe the symptoms and have an idea of the=20
resolution (stop the pain, feel better, etc.). This is the strength of=20
Method-R (IMHO). It enables you to really drill down to a root cause of=20

ignore the problem (and accept it as a part of life) or don't have any=20
symptoms that you are aware of? Not to be morbid, but this illustrates=20

these types of problems, but I don't think they are all that common in=20

Just food for thought,
