Which two statements accurately describe the relationship between Database Management and metrics collected in OCI Monitoring service?

Database Management primarily functions by directly querying the managed database's internal performance views, such as the Automatic Workload Repository (AWR) and Active Session History (ASH), to gather detailed diagnostic data. This rich, database-specific information is then supplemented with broader infrastructure metrics (e.g., CPU, Memory, Storage) that are available in the OCI Monitoring service, providing a comprehensive performance overview. The data collection mechanism for these detailed metrics is independent; Database Management uses its own processes via the Management Agent or direct connections. However, the service is not entirely separate, as it publishes these collected metrics to the OCI Monitoring service under its own namespace (oracledatabase) for unified viewing, dashboarding, and alarming.

A. Database Management's core value comes from deep diagnostics obtained by directly querying the database, not by relying exclusively on the more high-level metrics in OCI Monitoring.
D. The service provides its features using a comprehensive set of automatically collected metrics; it does not depend on users to manually create and upload custom metrics.

1. Oracle Cloud Infrastructure Documentation, "Overview of Database Management": This document states, "To use Database Management, you must first enable it for a database. When you do so, metrics are automatically collected and sent to the Oracle Cloud Infrastructure Monitoring service." This confirms that Database Management has its own collection process (supporting C's premise of an independent mechanism) and that it integrates with OCI Monitoring by sending data to it (refuting absolute independence but supporting the overall model).

2. Oracle Cloud Infrastructure Documentation, "Use Performance Hub to Analyze Database Performance": This section details that Performance Hub uses data from the Automatic Workload Repository (AWR). AWR data resides within the database itself and is accessed via direct queries, which directly supports option B's claim that "Database Management directly queries the database for detailed performance data."

3. Oracle Cloud Infrastructure Documentation, "Database Management Metrics": This page lists metrics in the oracledatabase namespace, which are specific to the Database Management service. It also notes that these are in addition to metrics from the base database service (e.g., ocidatabase). This supports option B's concept of supplementing its own data with other metrics available within the OCI Monitoring ecosystem.
