This article mainly introduces 10 methods for detecting Python program running time, CPU usage, and memory usage, including using the Python decorator or external UnixShell commands, for more information about how to run complex Python programs, it may take a long time. in this case, you may want to improve the program execution efficiency. But what should we do?

These days I have been studying shell scripts and writing some system load and CPU monitoring script programs. Without nagios monitoring software, as long as the server can access the Internet, you can send an email to remind the administrator of the system load and CPU usage. I. install the shell script and write some system load and

look at how these 3 tools work and their pros and cons. Simulate high CPU usage Before we analyze these 3 technologies, we need to install a tool to simulate high CPU usage scenarios. We use CentOS as a test system and use the prime number generator in Mathomatic toolkit

High CPU is a common fault on website servers. Many windbg tutorials use high CPU as an example. I also met this on the company server in March. The entire debugging process was smooth and regular, but the final reason was very interesting. It was related to a Trojan behavior. The w3wp process of the website server oft

have been thinking about whether the program deliberately let the thread run on the specified CPU, which can improve operational efficiency, so specifically to write a code for CPU usage to draw a sine curve experiment, I use the AMD X4 641 CPU, four core four threads of the film.The code is as follows#include"stdafx.h
high. First, check the system process to determine the process that causes the CPU usage too high. SQL Server Profiler can easily monitor which SQL statements are executed for a long time and consume the most CPU resources. You can use SQL statements to view the CPU usage
Recently, I have read a part of the thread of CLR via C #, which greatly improves the understanding of the thread. As a result, I suddenly remembered a book I saw in guanggu bookstore in college about Microsoft's interview. After several pages, I found that the author was talking about the problem. At that time, I felt that this author was very good at B, because the level of food at that time was still relatively good. Then I forgot. (Of course I didn't buy that book, but I didn't expect to app

. When multiple virtual machines run simultaneously and the CPU usage of the virtual machine reaches 100%, the system will stop responding so that the system will go down. This is a fatal defect for applications. Therefore, it is a good way to limit the maximum processing capability of virtual machines. Www.2cto.comFigure Virtual Machine CPU resource
