An administrator needs to store numeric values that describe resource performance at regular intervals and analyze them in near real time with a time-series store. Which half of the Azure Monitor data platform fits this need?
- AAzure Monitor Metrics, which keeps numeric data in a time-series database Correct
- BAzure Monitor Logs, which keeps event records that you query with KQL
- CAzure Activity Log, which keeps the audit trail of control-plane writes
- DAzure Service Health, which keeps the status of platform-wide incidents
Why A is correct: Correct. Azure Monitor Metrics is the half of the data platform that collects numeric values at regular intervals into a time-series database optimized for near real-time analysis.
Why B is wrong: Logs holds log and trace records queried with KQL, not the time-series numeric store described.
Why C is wrong: The activity log records control-plane operations, not regular-interval numeric performance values.
Why D is wrong: Service Health reports platform incidents and advisories, not a time-series store of resource metrics.
