Which term describes service-specific indicators that are directly tied to service level objectives?

• A. KPIs
• B. Metrics
• C. Observability triad
• D. SLIs

Answer: (D)

SLIs are service-level indicators that measure how a service performs against its defined targets. They’re built specifically for the service and directly map to the goals set in the service level objectives, so they provide a concrete, objective view of whether the service is meeting its commitments. Examples include availability, latency, and error rate—things you can measure to determine if the service is performing as promised.

KPIs are broader business metrics and aren’t inherently tied to a particular service’s operational targets. Metrics is a general term for any measured quantity and doesn’t imply alignment with SLOs. The observability triad refers to data types—metrics, logs, and traces—that you collect to understand system behavior, not to the specific indicators used to gauge service performance against SLOs.
