How is server load generally calculated?

Server load is primarily calculated by evaluating the CPU usage, memory usage, and the number of active processes. This approach provides a comprehensive view of how the server's resources are being utilized at any given moment. CPU usage indicates how much processing power is being consumed, while memory usage reveals how much RAM is being allocated to different applications and processes. Active processes reflect the current workload the server is managing, showcasing both the number and complexity of tasks the server must handle.

Together, these metrics give IT professionals a clear perspective on the server's performance and capacity. High levels of CPU or memory usage can signal that the server is under heavy load, potentially affecting response times and overall system performance. By monitoring these key indicators, system administrators can make informed decisions regarding resource allocation, optimizations, or the need for scaling up infrastructure to meet demand effectively.

In contrast, while network traffic, the number of connected users, and disk space usage can influence overall system performance, they don't directly represent the server load like the core metrics of CPU and memory usage do. Thus, these other factors are secondary when calculating server load.
