Which three tools can be used to monitor the usage and activities of Autonomous Database on Dedicated Infrastructure? (Choose three.)

Autonomous Database on Dedicated Infrastructure offers several integrated and external tools for comprehensive monitoring. The OCI Console provides native monitoring through OCI Metrics, which tracks resource consumption like CPU and storage, and Performance Hub, which offers detailed real-time and historical database performance analysis, including ASH analytics and SQL monitoring. For centralized, fleet-wide management and deeper diagnostics across hybrid environments, Enterprise Manager Cloud Control can be configured to monitor Autonomous Databases on Dedicated Infrastructure, providing a single pane of glass for both cloud and on-premises assets. These three tools provide a complete monitoring solution for usage and activities.

A. RMAN: RMAN (Recovery Manager) is an Oracle utility primarily for database backup, recovery, and restoration tasks, not for general performance or activity monitoring.
B. Logs: Logs (e.g., alert, audit) are a source of raw data about events, but they are not a monitoring tool. Tools like OCI Logging, EM, or others are used to analyze these logs.

1. Oracle Cloud Infrastructure Documentation - Performance Hub: "Use Performance Hub to Monitor Autonomous Database". Performance Hub is the primary, built-in feature for monitoring real-time and historical performance of an Autonomous Database. It provides graphical views of ASH analytics, SQL monitoring, and other performance data. (Doc ID: Use Performance Hub to Monitor Autonomous Database)

2. Oracle Cloud Infrastructure Documentation - OCI Metrics: "Monitoring an Autonomous Database with Oracle Cloud Infrastructure Metrics". This document explicitly states that Autonomous Database metrics are available through the OCI Monitoring service. It details the available metrics, such as CpuUtilization, StorageUtilization, and SessionCount, which can be viewed in the OCI Console or accessed via the API.

3. Oracle Enterprise Manager Documentation - Managing and Monitoring Autonomous Database: "You can use Enterprise Manager to monitor and manage Autonomous Databases on Dedicated Exadata Infrastructure... Enterprise Manager provides you with a complete, cost-effective, and easy-to-use solution for managing Autonomous Databases." This confirms Enterprise Manager Cloud Control as a key monitoring tool.
