An alert-threshold is a numeric or categorical value configured in a monitoring system that, when exceeded or crossed by a measured signal, triggers an alert condition. Its parameters include the signal identifier, the threshold value, the comparison operator (greater-than, less-than, within-range), the evaluation window, and the alerting action to take. It persists as a configuration entry in monitoring tools (Prometheus rules, Datadog monitors, PagerDuty thresholds) and is managed through infrastructure-as-code or operational configuration systems. The threshold encodes an organizational judgment about acceptable deviation into a machine-evaluable predicate. [formal: threshold | substrate: mind | horizon: a moment | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
A human-made SRE construct: a numeric or categorical value configured in monitoring systems that, when crossed by a measured signal, triggers an alert. It encodes organizational judgment about acceptable deviation into machine-evaluable form, persisted in configuration management systems and operational runbooks.

An alert-threshold is configured for the sake of alerting: its purpose is defining the level at which a signal becomes an actionable alert. The servant (threshold) points at the master (alerting).

Alert thresholds are parameters that define when system deviations trigger alerts. Their designed purpose is to support monitoring — specifically anomaly detection. For whose sake are thresholds configured? For monitoring.
