What is the main role of the 'vCenter Operations Manager'?

The primary role of the 'vCenter Operations Manager' is to provide performance monitoring and health metrics for virtualized environments. This tool allows administrators to gain insights into the performance of their virtual machines, hosts, and overall infrastructure. By analyzing various metrics such as CPU utilization, memory usage, and network performance, the Operations Manager helps in identifying potential issues before they affect the performance of applications and services running in the virtual environment.

Furthermore, it enables automated alerting based on predefined thresholds, giving administrators the ability to respond quickly to performance degradations or resource shortages. Visibility into the health of the virtual environment allows for better capacity planning and optimization, ensuring that resources are used efficiently.

While other options relate to important aspects of virtualization management, they do not capture the primary focus of vCenter Operations Manager, which is centered specifically on monitoring and providing insights for performance and health metrics.
