Virtualized performance monitoring is a process of tracing, aggregating, monitoring, and analyzing the performance metrics of a virtualized environment. It is intended to improve the stability and resource utilization of the virtualized environment. Virtualized performance monitoring provides the following benefits:

1. Ensure business continuity: Monitors key metrics related to CPU, memory, disk IO, and bandwidth in real time to identify and resolve potential issues at the earliest opportunity, preventing business interruptions caused by performance degradation or defaults.
2. Improve resource utilization: Abstracts and shares resources through the virtualization technology to improve the CPU utilization of physical servers from 15%-20% in traditional mode to 60%-80%. Performance monitoring can help optimize resource allocation to avoid resource waste or overloading, reducing the resource cost.
3. Simplify O&M management: Centrally manages all VMs with monitoring tools, such as SCP and third-party tools, to quickly troubleshoot issues, schedule resources, and create backups. This greatly reduces the O&M complexity. For example, resource demands can be estimated based on historical data analysis to support resource optimization.
