Question 24
ObservabilityWhich of the following is NOT one of the three pillars of observability?
Correct answer: C
Explanation
Observability is built on three pillars: metrics, logs, and traces. Alerts are a monitoring response mechanism, not one of the core pillars used to understand system behavior.
Why each option is right or wrong
A. Metrics
B. Events
C. Alerts
The three core observability data types are metrics, logs, and traces; alerts are not a pillar but an operational action taken after monitoring detects a condition. In standard observability frameworks, alerts are derived from thresholds or rules applied to those three signals, so they sit outside the foundational triad rather than within it.
D. Traces
