Observability · Flashcard
What are the three primary telemetry signals in observability?
- AMetrics, logs and traces
- BAlerts, dashboards and reports
- CCounters, gauges and events
- DSpans, labels and samples
Why this is the answer
Metrics, logs and traces are the three pillars/signals of telemetry. 'Alerts, dashboards and reports' are consumption surfaces built on signals, not signals themselves. 'Counters, gauges and events' are metric instrument types plus a log-like concept, not the three signals. 'Spans, labels and samples' are sub-components — a span is part of a trace, a label tags a metric.
