I agree with Ryan, that in a technical sense this is bogus. But I also feel there is a grain of truth in it. Often at its core the question has to do with comfort, and if recent incidents have caused a loss of comfort, then you get some sharp questions to answer. My strategy would be to increase the level of comfort, but don't commit yourself to wasting a lot of time once the sense of comfort returns. Here is what I would consider legitimate:

Install an alert log scanner that will email you when an error occurs. There are several free ones available on-line.
If you've experienced a recent crash, demonstrate you are taking serious actions to ensure this problem doesn't recur. Actions like monitoring.

Here is what I consider bogus:

Constantly monitoring the buffer cache hit ratio.

Marginal - run STATSPACK at regular intervals. I have had situations where the database would suddenly "hang" or "freeze" or "slow-down". I found that a couple of STATSPACK snapshots could provide a wealth of information about what was going on at the time of the incident. Now, my strong preference is to be notified so I can manually trigger these snapshots, but if it makes someone feel better and get off my case if I have them run at regular intervals, then I'm okay with that.
