Cpu display information that you may not understand in CentOS command top When using the top Command, the following line is displayed: What are the meanings of each value in it? I was asked this question today and found that the answer is not very clear. Sure enough, the most frequently used top commands every day are still unknown... Shame... So I checked some information:Official explanation Cpu (s) indi

Tags: priority GitHub official item CTO how RTU iowait RelatedAdd by Zhj: Here's a good explanation of what WA means in the top command, and we know that when Io is blocked, the operating system changes the process to a blocking state, and the CPU is scheduled to run other processes.When the CPU is idle, it checks for blocked IO (disk or network), and if so, it is WA; if not, that is the real idle. In the t

CPU load observation and performance monitoring in CentOS CPU load and Utilization CPU load and utilization are two different concepts, but they can all be viewed in the top command. CPU utilization shows the percentage of CPU occupied by the program in real time during runn

This article describes how to use cgroups to restrict cpu resources in Linux to avoid a process occupying all CPU resources. For more information, see This article describes how to use cgroups to manage cpu resources. Let's talk about the cpu usage of the control process. When running multiple programs on a machine tha

You will see this line when you use the top command:What are the meanings of each of these values?Asked this question today, I found that the answer is not very clear. Sure enough, every day with the most top command has not been well-acquainted ... Ashamed... So I looked up some information:Official explanationThe CPU (s) represents the CPU information. The meaning of each value is:Us:user

Basis of judgment:A physically encapsulated CPU (judged by physical ID) can have multiple cores (differentiated by Core ID).Each core can have multiple logical CPUs (judged by processor).One core implements this core's own hyper-Threading technology through multiple logical CPUs.The CPU cores entry contains the number of cores in the same physical package.The siblings entry lists the number of logical proce

1. Indicator Range 1.1 User mode CPU utilization+ System Mode CPU UtilizationReasonable value: 60-85%, if the us+sy time in a multiuser system exceeds 85%, the process may take time to wait in the running queue, the response time and business throughput will be compromised; the US is too large to indicate that there is a user process that consumes a lot of CPU ti

The overclocking of the computer is to improve the working frequency of the CPU, graphics and other hardware by artificial way, so that they work stably under the rated frequency state. The Intel P4C 2.4GHz CPU For example, its rated operating frequency is 2.4GHz, if the operating frequency to 2.6GHz, the system can still run stably, then the overclocking was successful. The main purpose of

I. Preface in order to understand the meaning of this article more conveniently, it is better to look at the following cumbersome concepts and make it easier to understand. Do not understand these concepts, even after reading you can only know, run the next vmstat, look at the results of Linux feedback, but also to know why ~ First said the concept of memory. It's not about the CPU. Because the memory will consume

Choose 533 or 667? Detailed description of the relationship between CPU and memory I recently read some questions from some netizens about CPU, such as the gap between front-end bus 533 and 667, and how about the memory of ddrii667 on t2050 (Front-End bus 533 MHz ?...... I want to write thisArticleSo that more friends can understand this layer-by-layer relationship and know how to choose

A computer overclock increases the operating frequency of CPU, video card, and other hardware manually so that they can work stably at a higher rate than its rated frequency. Taking intel p4c 2.4ghz CPU as an example, its rated operating frequency is 2.4 GHz. If the operating frequency is increased to 2.6 GHz, the system can still run stably, and the overclocking is successful. The main purpose of

A while ago, I suddenly became interested in the working principle of computer hardware. Therefore, I read some documents, and I have summarized and understood (and guessed) them. I will give you the following article. Appendix: This article only analyzes the CPU interruption technology theoretically, but does not analyze the implementation of the interrupt technology. Ready Go Directory 1. What is CPU int

Because of the management problems in our alization are caused by the annoyingly popular desirable host Migration Feature! I previusly talked about PCI device addressing problems, but this time the topic to consider is that of CPU models. every hypervisor has its own policies for what a guest will see for its CPUs by default, xen just passes through the host CPU, with qemu/KVM the guest sees a generic mode

Loadaverage is displayed when we use the top command to view system resource usage, as shown in. It indicates the average workload of the system in 1, 5, 15 minutes. So what is the load? What is the relationship between it and cpu utilization? When we use the top command to view the system resource usage, we will see the load average, as shown in. It indicates the average workload of the system in 1, 5, 15 minutes. So what is the load? What is the rel

I tried to detect Keyboard Events in python by placing a function event. get () in pygame IN THE while loop. The result is that the cpu usage is always 100%. However, the event listening functions in the operating system and other languages (such as C #) basically do not occupy the cpu. How do they do this? Does it sacrifice the real-time response of events? I tried to detect Keyboard Events in python by pl

General CPU failure has the following: thermal failure, restart failure, black screen fault and overclocking failure (CPU go to die, of course, do not forget) 　One, the CPU pin contact is bad, cause the machine can not start General performance in a sudden unable to boot, the screen shows no signal output, excluding video card, monitor no problem, unplug the

In the DIY computer field, many players in the installation, attention is often focused on the computer performance of the CPU, graphics, motherboards, memory, hard disk and other core hardware, on the chassis power, radiator and other hardware often do not care too much. Because of this, some friends assembled computers are often equipped with some of the inferior radiator, cottage chassis power supply and so on, in the future when used, it is very e

Which tools can view CPU load?You can use the top command, the uptime command, and especially the top command, to be powerful, not just to see the CPU load.How is CPU load understood? is CPU utilization not?To differentiate between CPU load and
