Signal-to-noise ratio: the proportion of monitoring alerts

Signal-to-noise ratio: the proportion of monitoring alerts that are genuine and actionable versus those that are false, irrelevant, or redundant, used as the primary metric for evaluating the effectiveness of a monitoring system

Why This Is a Definition

This definition precisely establishes what the term means by identifying it as a proportion measurement, specifying what constitutes 'signal' versus 'noise', and articulating its role as the primary evaluation metric. It distinguishes this concept from mere data volume or frequency.
