Monitoring Linux system performance every day is a daunting task for every system/network administrator. After 5 years of Linux system administrators in the IT industry, I found it's not easy to monitor and keep the system up and running, so I've summed up 8 very useful command-line tools for Linux/unix system administrators. These commands support all Linux systems and can be used not only to monitor the s

A fully running Linux system consists of many subsystems (introduction, Cpu,memory,io,network, ...). ), monitoring and evaluating these subsystems is part of the performance monitoring. We often need macroscopic view of the whole system state, also need microscopic look at the operation of each subsystem. Fortunately, we don't have to reinvent the wheel to monitor these subsystems with the tools available,

System Performance analysis Tools The above sections describe several aspects of how Linux performance is affected and how to solve them, but how do you find out from the system that something is wrong with a certain aspect or a few aspects, which requires the use of several common performance analysis

For system and network administrators, it is a heavy task to monitor and debug the performance of Linux systems on a daily basis. After 5 years working as an administrator in the IT field as a Linux system, I gradually realized how difficult it was to monitor and keep the system up and running. For this reason, we have written a list of the 18 most commonly used command-line tools that will help each Linux/

When writing a network service, it is more concerned about how many concurrent connections the service can achieve, and how much interactivity can be achieved on the basis of this connection. Writing a service is a very hard thing to do, But also to write a test tool that can reflect the results of more consumption of working time. The following is a test tool that can be easily set up to perform high concurrency and high-swallowing performance tests

Are you still writing a lot of CSS code for creating Border rounded corners? Every time you encounter such a problem, you will rewrite that set of code, which is troublesome and boring. Does it increase the pressure on the server because it does not use technology? Does the Code remain like this? Is the CSS Code that has been written for several years still the old one? If it is good at accumulation, the tool already exists, and new and advanced technologies are constantly created. Using these C
