How to view machine configuration under Linux? cpu/Memory/HDDDmesgDisplays the boot information. The kernel will store the boot information in the ring buffer. If you are too late to view the information, you can use DMESG to view it. The boot information is also saved in the/var/log directory, in a file named DMESGDmesg|grep HDHard diskDmesg|grep CPUCpuDMESG|GREP procMemoryDmesg|grep RedhatOperating systemDmesg|moreMore informationUname-aOperating sy

Solving the performance problems of a database system can be a daunting task. It is important to know how to find the problem, but it is more important to understand why the system responds specifically to specific requests. Affect CPU utilization on the database server There are many factors: compiling and recompiling SQL statements, missing indexes, multithreaded operations, disk bottlenecks, memory bottlenecks, routine maintenance, and extraction,

Many people in the process of using a notebook, often pay attention to their CPU performance, we will see the notebook CPU model behind the usual "U", "M" and other words, and "u" is the meaning of low pressure, "M" is the meaning of the standard pressure. Recently, a lot of net users of notebook CPU low-voltage and high-pressure difference is not very understand

Objective:Performance optimization is a commonplace topic, typical performance problems such as slow page response, interface timeout, high server load, low number of concurrency, database frequent deadlock and so on. Especially in the "rough fast" Internet development model of the big line today, with the increasing number of system access and code bloated, a variety of performance problems began to pour.There are three factors that can affect application performance at the system level:

In the absence of nagios monitoring software, as long as the server can be on the Internet, you can send mail to remind the Administrator system load and CPU usage. First, install the following Linux mail client msmtp software (similar to a foxmail tool) 1. Download and install:Http://downloads.sourceforge.net/msmtp/msmtp-1.4.16.tar.bz2?modtime=1217206451big_mirror=0 Copy Code code as follows: # tar JXVF msmtp-1.4.16.tar.bz2 # C

Computer use for a long time, it is inevitable that such a failure. In many computer failures, board card class appears the most likely. Although the CPU is an important part of the computer, but the probability of failure is relatively small, common CPU failures are roughly the following: thermal failure, restart failure, black screen fault and overclocking failure. Because the

CPU processor is a PC computer, one of the most important accessories, the operation of various data, processing and other processes are done by the CPU processor. If a computer is compared to a human body, then CPU processor can be regarded as the human brain, control the whole machine parts of the phase to coordinate operation. Due to the high integration of

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 management: page swappingUser Process Management: Process start and context swit

We can use/proc/cpuinfo to view CPU information. This file contains the data section of each processor on the system. There are six entries in the/proc/cpuinfo description for multi-core and hyper-thread (HT) technical checks: processor, vendorid, physicalid, siblings, coreid and cpucores. We can use/proc/cpuinfo to view CPU information. This file contains the data section of each processor on the system. T

IBM products are the main bar. As early as the Pentium motherboard bus frequency has 50.60.66MHz three kinds, The frequency of the PENTIUMCPU is generally 75.90.100.120.133.150.166.200.233.266.300.MHz. Motherboard and CPU speed is different, in order to coordinate the speed between the two, in the motherboard generally there is no "frequency multiplier factor" Jumpers are used to set the multiplier relationship between the two, currently popular mothe

Layer-3 Ethernet switches are quite common, so I have studied the problems related to the CPU packet sending and receiving of layer-3 Ethernet switches. I would like to share them with you here, hoping they will be useful to you. Layer-3 Ethernet switches are developing rapidly. On the one hand, bandwidth and switching capacity of network devices are greatly increased, and the types of protocols supported by devices are also increasing with the increa

Why is the server so slow? CPU, RAM, and disk I/O resources are exhausted, and ram is used up Machine running is slow because it consumes too many system-specific resources. The main resources of the system include CPU, RAM, disk I/O, and network. Excessive use of any of these resources puts the system in trouble. However, if you can log on to the system, you can use a large number of tools to determine the

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

■ Pisces We have done a lot of articles about CPU, but for most users, we may not have the opportunity to split the CPU in the chassis. Therefore, this time, we will learn about our processor through the system and simple software methods. EntryIf you only want to know your CPU model, Windows Me/2000/XP operating systems can help us complete this task. After ente

0. Why write this blogThe top or PS of Linux can see the CPU utilization of the process, so why do you need to know this detail? There are three reasons for writing this article:* Want to be able to get process CPU utilization in a script in a "non-blocking" way * PS cannot get CPU utilization at the current time of the process; top takes at least 1 seconds to ge

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

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
