The testing, debugging, and performance testing tools that are readily available in linux are originally named test, debugging, and performance tools that come with linux, but they are not appropriate. for example, gdb mentioned in this article, many Linux distributions provide it, but after all it is not a necessary p

Enterprises regard their websites as the key business of daily operation. To maintain optimal performance for key business functions, Linux administrators need a variety of tools to help them easily and effectively monitor Web servers. The following three open-source tools can help Linux administrators better understand their Web server features, potential securi

When there is a problem with the Linux system, we not only need to look at the system log information, but also use a lot of performance monitoring tools to determine what part (memory, CPU, hard disk ...). ) out of the question. In the Linux system, all the operating parameters are saved in the virtual directory/proc, in other words, we use the Performance monit

Linux command-line tools:1, Top command: can display the system each process occupies the resource condition.2. SAR command: the system CPU and memory can be sampled periodically.3,vmstate command: It can count the CPU and memory usage and swap usage information, can also be periodically statistical information.4.iostat Command : Provide detailed IO information5,pidstat command: not only can detect the process, but also to detect threads.Windows Inspe

JoeZonkerBrockmeier mentioned five tools to monitor and improve Linux system performance in an article on the Linux Foundation website. These five tools cover kernel optimization, network monitoring, and system monitoring. they are KDESystemMonitor, Dstats, TheSysstatAuite, network monitoring using Ifstat, and Li Joe Zonker Brockmeier mentioned five

During the maintenance of the application to the customer, I noticed some performance issues under high load. In theory, increasing the load on the application can degrade performance ratios. However, I think the rate of performance degradation is much higher than the load. I also found that performance can be improved
