What can be enabled to obtain granular OS level metrics from an Amazon RDS database?

1. Standard Monitoring

2. Enhanced Monitoring

3. AWS CloudWatch Logs

4. AWS Systems Manager

The correct answer is: Enhanced Monitoring

Enabling Enhanced Monitoring on an Amazon RDS database provides a rich set of granular metrics that are specifically focused on the operating system level. This enhancement allows you to gain insights into the database instance's performance, including CPU usage, memory usage, disk reads and writes, and other crucial metrics that can affect database operations. Enhanced Monitoring operates at the operating system level and provides real-time metrics collected from the RDS instance, which can be invaluable for troubleshooting performance issues and optimizing database configurations. It offers a more detailed view than Standard Monitoring, which primarily provides metrics focused on database-level performance but lacks insights into the underlying OS metrics. The other options do not provide the same level of detail with respect to OS-level metrics. Standard Monitoring does not go into the operating system particulars. AWS CloudWatch Logs mainly focuses on logging data rather than real-time OS performance metrics. AWS Systems Manager is a service that allows user management and automation across AWS resources but is not specifically designed for providing OS-level metrics for RDS instances. Therefore, Enhanced Monitoring is the appropriate choice for obtaining granular OS level metrics from an Amazon RDS database.
