In Linux, the meaning of CPU load and CPU usage indicates that the Nagios alarm information was viewed yesterday. It was found that the CPU load on one of the servers was too heavy and the machine was CentOS.

When we use the top command to see the system's resource usage, we see load average, as shown in. It represents the average workload of the system at 1, 5, and 15 minutes. So what is load? How does it relate to CPU utilization?Load average: The system average load is the load of the CPU, which contains information that is not

CPU usage is actually the CPU resource that your program runs on, indicating that your machine is running a program at some point in time. Higher usage means that your machine runs a lot of programs at this time, whereas lessThe top command is a common system performance analysis tool under Linux that allows you to vie

I used to hate those ops. When I saw CPU usage 100% , I shouted wildly, and I once said, if the CPU is not used, is it used for idle? It seems to me that what I said is quite reasonable. But, I was wrong ... But that doesn't mean that OPS is right, and that after 100% of the CPU
