build.obs-alert-noise Calculator
Calculates alert noise rate from false positive percentage and total alert volume, and shows the mean time to acknowledge (MTTA) degradation from alert fatigue. Alert fatigue is the primary cause of missed real incidents — reducing false positive rate below 5% is the standard target.
Inputs
Alerts Day
Reference formula or conversion factor shown for context.
Fp Rate
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Ack Min
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Results
false positives/day
Reference formula or conversion factor shown for context.
true positives/day
Reference formula or conversion factor shown for context.
MTTA
Reference formula or conversion factor shown for context.
noise ratio
The proportional relationship between two quantities.
