load average

More and more people are beginning to touch the Linux operating system, from VPS to the brushless system (such as OpenWrt, Tomato), but also essential to a variety of probe and system monitoring interface to see "System average Load" or "load

Metrics to measure CPU performance:1, the user uses the CPU situation;CPU runs regular user processesCPU Running niced ProcessCPU running real-time process2, the system uses CPU condition;For I/O Management: interrupts and drivesFor memory

When a Linux system encounters a problem, we not only need to view the system log information, but also need to use a large number of performance monitoring tools to determine which part (memory, CPU, hard disk ......) An error occurred. In Linux,
