CPU Utilization
CPU utilization is a performance metric that measures the percentage of time a central processing unit (CPU) is actively executing instructions versus being idle. It indicates how much of the CPU's processing capacity is being used by running processes, threads, or system tasks. High utilization can signal heavy workloads, while low utilization may indicate underused resources or potential bottlenecks elsewhere in the system.
Developers should monitor CPU utilization to optimize application performance, identify resource bottlenecks, and ensure efficient system scaling in production environments. It is critical for debugging performance issues in compute-intensive applications like data processing, gaming, or real-time systems, and for capacity planning in cloud or server deployments to avoid over-provisioning or under-utilization.
