What type of monitoring does OCI's monitoring service emphasize?

The Oracle Cloud Infrastructure (OCI) monitoring service prioritizes real-time automatic data collection and analysis to ensure that resources are continuously monitored without the need for manual interventions. This capability allows for immediate detection of changes in resource performance or availability, enabling organizations to respond rapidly to any issues that may arise.

By emphasizing real-time monitoring, OCI supports proactive resource management, helping to prevent potential downtime and maintain optimal performance levels. Automatic data collection ensures that metrics such as CPU usage, memory utilization, and network traffic are consistently gathered and analyzed, allowing for detailed insights into resource behavior over time.

The other options do not align with the core functionalities of OCI's monitoring service. For instance, periodic manual checking or monthly summary reports are not efficient for immediate resource management, as they involve delays that could lead to unresolved issues affecting service performance. Additionally, while user reporting can be helpful, it lacks the automated and continuous nature that real-time monitoring provides, which is essential for maintaining cloud resource health and performance.
