Active labeling is a process that programmatically attaches operational metadata to events, telemetry, and data points in real time to improve routing, triage, model training, and automated actions. Analogy: like an automated triage nurse who tags and directs every patient before a doctor sees them. Formal: a runtime system for attaching dynamic labels to telemetry and data to enable policy, ML, and operational automation.<\/p>\n\n\n\n
Active labeling is the runtime practice of applying context-rich, dynamic labels to telemetry, traces, logs, metrics, events, data samples, or user requests. Labels are added as data flows through the system based on rules, ML models, or policy engines, and they are used downstream for routing, alerting, model training, analytics, and access control.<\/p>\n\n\n\n
