ratio

Trips when the relationship between two different metrics is imbalanced.

How it works

Evaluates the proportional relationship between a numerator and a denominator. This logic is asymmetric; it identifies when the two metrics diverge from their expected relative scale.

When to use

  • Capacity planning (Requests per Worker).
  • Cost efficiency (Operations per Dollar).
  • Complex resource balancing (Cache Hits vs. Misses).

When not to use

  • When the two metrics are unrelated.
  • When the denominator frequently reaches zero.
