Mastering troubleshooting techniques for high CPU usage is paramount for DevOps engineers due to its multifaceted impact on system performance, scalability, and cost efficiency.

By identifying and resolving CPU bottlenecks, engineers can mitigate the risk of performance degradation and maintain optimal resource utilization. Efficient CPU management is essential for scalability, enabling applications to seamlessly handle increasing workloads without compromising performance.

Through proactive troubleshooting and optimization, engineers can design scalable architectures that adapt to evolving demands, ultimately reducing infrastructure costs and enhancing cost efficiency in cloud environments.

What is CPU Usage

CPU usage refers to the percentage of a central processing unit’s (CPU) processing capacity that is currently being utilized by the system or a specific process.

It represents the amount of time the CPU spends executing instructions for various tasks, such as running applications, handling system processes, and processing input/output operations. CPU usage is typically measured as a percentage over a certain period, with higher percentages indicating a greater workload on the CPU.
