As @tscroggins says, it is not possible to "completely avoid" the false positives and false negatives. At the end of the day, as with a lot of things, it comes down to money. How much does it cost you / your organisation to respond to a positive alert only to find it was a false positive and therefore "wasted" cost? How much does it cost you / your organisation / your customers if you miss an "incident" due to a false negative? Lost orders? Damaged reputation? SLA breaches? These considerations can be taken into account when putting together a business case for improving your monitoring, taking on extra staff to respond to alerts, improving your infrastructure to reduce latency, rewriting your applications to be more robust and/or self-healing, etc. etc. Start looking too deeply and you won't sleep at night! Find a good enough / tolerable level of monitoring that gets you close but doesn't cost the earth!
