Identify the most cost UNIX process CPU



Multi-user UNIX computer systems running the process, sometimes feel a sudden slow down processing speed, and sometimes even characters from the keyboard is also too long a response will be. Experienced people will know, then the computer must run a CPU-consuming process. This process is sometimes an individual account in the implementation of a CPU process, sometimes there may be unforeseen circumstances out of the system, the system itself during processing. In either case, the system administrator to find out that the process should be timely and make the appropriate treatment.

Although UNIX provides the "acct" and a series of accounting procedures, but these procedures can only be displayed after the process run time and CPU-time information, not real-time unit of time, a process which occupied the most CPU time.

To do this I use the shell language for a program to provide some of the use of UNIX utilities to achieve the above functionality.

This section contains procedures ps, cut, diff and other UNIX utilities, the following briefly explain the functions of these utilities.

ps: to display the current system processes information. With the-e parameter is displayed in the system processes information. Use the-f parameter is showing the process of complete information;

cut: used to trim the file as a unit. Parameter "-c -15,33 -" that the input file before each line 15 characters and 33 characters after the end of the line until all the characters into the output file;

echo: used to screen prompts;

sleep: shell program can wait for several seconds, and then run behind the statement;

diff: used to compare two files, differences are displayed;

sort: the file can sort the various lines, sort the results can be displayed;

grep: can be used to find the file the line to meet certain conditions. Parameter "^" means to find the first lines as a space;

|: The pipe symbol, can be realized to the back of the previous command's output as the role of the command input, so you can omit the intermediate files generated steps to improve the efficiency;

>: That of the output redirected to should have been something on the screen output to a file.

Procedure as follows:

ps-ef | cut-c -15,33 -> tt1

echo Please wait a while ...

sleep 20

ps-ef | cut-c -15,33 -> tt2

echo Attention!

echo

diff tt1 tt2 | cut-c 2 -> tt3

sort tt3 | grep ^ | cut-c -83 | grep-v 0:00

echo

echo That is ok!

rm tt1 tt2 tt3

First of all, the system processes all the processes to obtain information and put them into useful fields in the temporary file tt1. Then the program to wait for 20 seconds (adjusted time with specific cases).

Then the process again to obtain all the information and put all the fields in the temporary file tt2.

Compare the two temporary files, find the 20 seconds before and after the information on those different processes (of which there is consumption of CPU time the process has been changed).

Generated when compared remove the ">" and "<", the results placed in the temporary file tt3.

Tt3 content on the sort to spend CPU time to change the process of around the same row with the information. grep "^" is used to remove the implementation of this program produced a number of shell commands the middle of the process information.

Then cut each line is too long deleting process information, make the output clearer. The grep-v 0:00 is used to remove only occurs once in 20 seconds before and after the process. Program execution now, at 20 seconds of CPU time spent before and after the different processes is displayed on the screen, and from which you can easily find out by looking for the process. Finally, to not leave the system useless junk files, but also to all the three temporary files deleted.

REALDRAW help you reproduce wooden speaker

Note: This training is appropriate against such PHOTOSHOP and other graphics software on the experience of the user to a certain extent

REALDRAW from mediachance company. Famous multimedia software Multimedia Builder is the company's products.

Look at the startup screen REALDRAW it:



I tell you, this picture is REALDRAW by all is: the real hand, pens, as well as the SONY digital camera and so on.

I remember when I first contacted REALDRAW in the last year, I do not remember a specific time. Bored at the time when the Internet occasionally downloaded software. When I see the following Samples of these when I was feeling real performance capabilities of its deeply moved.







I think you like me to see these Samples after the first, there is a rookie-like feel incredible, there is a strong sense of excitement and the creative impulse, right?




[Next]



Well, we look at her main interface:



You got the impression that it? My feeling is that the interface is very streamlined and very easy to get started.

Let us look at her "real effort" section:



The panel is now streaming the first style defined functions. We can be very flexible at any time add, modify, delete all the results. Here I must mention is the 3D lights to this, I think it is REALDRAW most innovative feature, is well known. We can see the real world the role of light absorbed. We also use objects to simulate the real simulation of light. In the past to simulate the effect of light, usually with a gradient to achieve. This method is very inconvenient, if not profound skills, can not be very real. I think this is very convenient REALDRAWR vector source software may draw it in 3D. Surface Skin also a feature of this, he can on the human skin, clothes and other fabrics simulate real textures.

Here are some other panels I would like to also introduce a small, experienced I want to see at a glance if you have a preliminary understanding on the REALDRAW. Got it all, get the http://www.mediachance.com/ when a down it! ! (About 10M or so)

Interview with B & Q (China) Vice President, Human Resources Director Miss Hu Weiyan


Reporter: B & Q has a credo: "high-level management and well-trained staff to give customers 100% satisfaction," NA me is how B & Q staff training, so that B & Q are the same for each employee trained ?

Hu Wei Yan: B & Q than the internal training system, according to various posts with the corresponding required course, to store on the training, for example, the organizational structure of the B & Q store and deputy manager, department managers and general employees, and the company on each level of the employees have coverage. General staff training focused on three main areas: product knowledge (Product Knowledge), Customer Service (Service Skill), there is a sales technique that is (SalesSkill). In addition, new employees are the company standard of induction training. Manager and the director and deputy manager needs some leadership (Leadership), data analysis, business development, performance improvement and other training, such as how he managed to motivate employees (Motivation), how to develop their potential and so on. In addition, the company has three levels of training future managers, internal employees to encourage their development, and company growth. Employees can develop their own career interest to apply, through the company transparent, just and fair channels, get managers the necessary training, successfully passed all the training, once the company has the appropriate job vacancies, will be promoted.
Reporter: B & Q is now recruiting from the campus of the University of fresh students for management trainee, and also has extensive management experience in the recruitment of some people who join, the present in terms of their performance now, which means you have more satisfaction?
Hu Wei Yan: It is too early to say this, B & Q recruitment of university graduates as management trainees, 2002 is the first, is the second year, B & Q is now in rapid development period, the new company plans next year to open nine stores, if each store's management about the terms of 20, opened nine stores will need about 180, not including other support departmental managers. These vacancies, we are filled primarily by three ways: First, the effective promotion within the company, is through a transparent and fair evaluation system, promote a management capacity of staff to play; second is from outside the company to recruit a number of practical experience, and in accordance with B & Q the management of corporate culture required to play; Third B & Q looking to the future that he has the potential to train a lot of management trainees to meet the rapidly growing business needs.
Note: B & Q has developed rapidly in China, from 200 employees in 1999 to the present rapid growth of 5,000 employees, NA me how B & Q's human resources department to operate efficiently: from staff recruitment to training to enable them play fighting in the short term?
Hu Wei Yan: I am, frankly, this experience really hard, as a rapidly developing company, talent selection, promotion and training of human resources and training centers so very busy. How to improve operational efficiency, a very important experience is to strengthen communication between departments, unified management of operational processes and strengthen the process. Open a new store, for example, to communicate with the various departments to coordinate the formulation of the new recruits? "369" principle, that is, three months ahead of general staff induction, deputy manager, department managers and key staff positions report six months ahead of schedule, the manager must give nine months of hillock, to corporate culture, departmental operating procedures, training and personal experience to combat the process of a shop. Human Resources in accordance with the Zhe Ge Shi Jianbiao pushed down, check the recruitment Jin Cheng Mei Zhou, Tong Shi Zhiliang standards to ensure staff - Xuan on Ren, the Baokuo two Cengmian mean, Yishijubei Gai the required abilities and skills second, Fuge and B & Q corporate identity and cultural requirements. Upon arrival staff, training center and front-line operations to ensure the implementation of classroom and on-the-job training for staff to meet requirements related posts. We believe that competent and excellent store managers to create and run a good working atmosphere, so that employees can happily work in B & Q and make them work, dedication, and through staff so that more customers to spend more in store money, spent good money on our products and services have a good reputation. Also within B & Q have a "grass-roots meetings," the calendar, marked the stores, regional Office, the headquarters of various departments held a "grass-roots meeting" of the time, any employee can be made at the meeting and work-related issues and suggested that senior leaders regularly to the meeting, listen carefully, engage in dialogue, are, together with deputy manager to store human resources manager, after the meeting to formulate solutions to the problems seriously, timeline to implement, its reference to the problem is beyond the Deputy manager of the provisions of authority, it must be fast to the company on a layer of management responses and implementation of the program and supervise the implementation, and the next time? "Grassroots conference" to resolve the situation informed questions.
Note: as 3M Company, Marine Corps and other agencies rely on training staff pride, Mary Kay and other means to increase through the celebration of employee satisfaction, NA me B & Q by what means to improve employee satisfaction it?
Hu Wei Yan: B & Q will not only improve employee satisfaction, and further increase employee engagement. B & Q is now the main point of co-operation with Gallup - Q12, B & Q staff through the survey that they collect, aggregate, data processing, the first line to help business managers to make a comprehensive plan of action for improving the work, gradually increase the dedicated staff rate. Gallup in September this year, the company collected nearly 1000 staff survey were, in different countries and different sectors of large amounts of data analysis and comparison, the company found that B & Q China, a relatively low score of the first two are: time to celebrate success and work The device, which shows that our line managers to encourage employees to give enough time, staff work the required documents, materials, equipment, distribution is not reasonable. Through this analysis, of crucial importance for the next part of that business units to develop specific improvement projects / measures and timetable to implement, improve the speed of each business unit manager who will Lieru related to one of the assessment indicators.
Reporter: B & Q's stores located throughout China, which will obviously result in the headquarters and branch, regional communication barriers, but also increased the difficulty of management, B & Q by Shen Yao-like methods to solve this problem? Hu Wei Yan: Yes, it is a challenge to management, I believe the development of enterprises of all is a challenge. In this regard, we spent a lot of time to explore, and is further perfected. Personally, I think: First of all, a clear division of the headquarters / regional office / store of the respective functions and powers; second, standardized company-wide communication channels include a variety of reporting systems and formats; Third, strengthen the construction of commercial data processing systems; Fourth, the unified standard crisis management procedures, etc.; Fifth, promote all the company's team spirit, sharing resources and best actual case / experience.
Reporter: You had the Chinese hotel industry, IT industry in the United States, in Europe's retail enterprises such different industries and different national contexts of the company worked these companies in human resources management should vary greatly, you are how to overcome these differences?
Hu Wei Yan: I is a relatively stable person, when I go to foreign hotel is six and a half thousand, simply did not thinking about jumping. At that time, five or six people to apply for a job competition, it is admitted, I have cherished the opportunity to study hard, at this stage, the basic is learning and absorbing, it laid for future development of good basis. Later, due to an accidental factors, I switched to an American IT enterprises (high-speed development period), personal feel quite friendly corporate culture and respect for the individual, along with a very comprehensive training system, so it feels great personal development space . As a result, hard working and hard work to continuously improve their professional knowledge and skills, and work to show their talent as much as possible, really hard work pays off, another six and a half later, his grown step by step up. B & Q came to me for the first executive search services, frankly speaking, I am biased, that British companies are too conservative and hierarchical, not for me, but the actual contact with headhunters and B & Q, I found, is not the case, In fact, Britain's B & Q corporate culture, or with my previous company, a service very similar to the U.S., I wonder if it is a coincidence? !
Different between the company's human resource management issues, I always think that should apply the dialectical point of view of dichotomy; which enterprises random system which has its two sides, the so-called positive and negative nature, the key is to see whether you have a positive heart of a (positive thinking), such as when facing a very difficult, if the degree of the face with a positive mind, you imagine yourself there will be a good opportunity to take up the challenge, and can test their the ability to be exceeded; if faced with a negative attitude, you may be back fear, unwilling to try. But had to admit: or should that different industries, different countries or different management style is quite big, such as the retail industry and IT industry is the relative quality of staff required, skills varied widely, the company developed a series of human resource management regulations is quite different and oriented. This depends on the individual business and debugging of familiarity (self-learning ability constant).
Reporter: In the human resources industry successful people like you, there are some new people just entering the industry, and to them that you have some kind of proposal Shi Yao?
Hu Wei Yan: I have three suggestions for reference. First of all, to change the concept, human resources department is not a power but a service support department, good service for your customers that all employees within the company, is one of your main goals; second, familiar / operational capacity and human resources to understand professional skills to simultaneously, which will help you to better service to your customers (business managers and front-line employees) and to establish good personal relations / reputation; Finally, failing to decision-making, there must be forward-looking. Matter-the ability to solve problems, while very important, but if a deeper, higher-level plans to make pre-and post solutions to prevent in the future, will help the company's decision-making faster, better, more efficient operations .

Miss Hu Weiyan Description:

Rutgers State University of New Jersey, United States, MBA, has 16 years of well-known foreign human resources management experience, worked in the Shanghai Yangtze Hotel, Motorola (China) Electronics Co., Ltd., is effective in B & Q (China), experienced the company's growth from 600 employees to nearly 5,000 business of rapid development.

UEC is an open source cloud computing environment, it and Amazon EC2 (Elastic Compute Cloud, Elastic Compute Cloud) the same, are based APIs (application program interface) as the basis. companies do benefit from the private cloud.

"In essence, the new version is specifically for cloud computing." Canonical director of corporate support and services Steve George said. To help in the Ubuntu 9.10 version, users set up in the cloud computing environment using the hardware can be in-depth use of cloud computing cores, including flexibility and resource sharing.

Users can set the 10 to 15 units of private server, and use the Amazon EC2 on the same application program interface to access and use the same function as the Amazon. George said that applications can take off Amazon "cloud", and then Switch to the user's own private cloud. or vice versa.

UEC is a comprehensive series of cloud computing technology, including the Eucalyptus project. This project provides an open source system, and hardware and software environment can have a mixed composition of clouds. Canonical said, UEC can easily deploy and manage cloud environment.

Eucalyptus project has aroused strong interest analyst Stephen O'Grady.

"For the release of the server computing, Eucalyptus project development is to allow people most interested in the topic, as it allows private cloud with Amazon and VMware achieve compatibility." O'Grady said.

Ubuntu 9.10, codenamed the past "karmic Koala", it also can serve as Amazon EC2 machine using a graphical environment to achieve and the cloud environment interaction. UEC interface and Ubuntu AMI image is the same, in a work environment can uploaded to other machines.

UEC's storage capacity is enough to support the user in Ubuntu corporate cloud environment, immediate deployment of new applications.
