Based on real-time data analysis, administrators can identify resource bottlenecks and optimize configurations, thereby efficiently adjusting resource allocation and improving overall system performance and operating efficiency. Implementation details: Total resource statistics: Comprehensive statistics of the total resources of the computing blades, including the number of CPU cores, memory capacity, and storage capacity. Through these data, administrators can obtain an overview of the system's resource configuration and understand the total amount and distribution of various computing resources. Resource usage: Real-time monitoring and analysis of computing blade resource usage, including the actual usage of the current CPU, memory, and storage.
