In the performance testing process, it is of great significance to monitor host resources. On the one hand, during the test, you can determine whether the pressurization is successful and whether the system can withstand the current pressure to ensure system security. On the other hand, after the test, you can sort the monitoring data, it can provide data support for performance analysis, problem discovery, and bottleneck search. This article will introduce the common resource monitoring

Collectl is a lightweight performance monitoring tool that monitors information such as CPU, disk, bandwidth, memory, network, NFS, and process. Monitoring System Resources is a necessary task for system administrators. We often need to monitor system resources to solve system problems. The Linux system also comes with many monitoring tools, such as top, vmstat, iostat, and SAR. It is very important to be familiar with these tools, but these tools a

Special character escape Because WEB applications need to be federated to multiple languages, each containing some special characters, for dynamic or tabbed languages, a problem that we often encounter when we need to dynamically construct the content of a language is the escape of special characters. The following are some of the special character types that Web developers most frequently need to escape: HTML special characters; JavaScript special characters; SQL special characters; If you do n

CodeSmith is one of the most widely used tools in code generation and has rich template resources and users. Many of my friends used CodeSmith and there are many ready-made templates. NCodeGenerate provides a template Conversion Tool from CodeSmith to NCodeGenerate. It makes it easier for users to switch from CodeSmith to NCodeGenerate. Next we will introduce it.

Ncodegenerate asCodeGenerate tool. You can edit templates, check syntax, and execute template generation code. If there is no logical error in the template, there is no problem in the whole process. But who can ensure there is no error in the written template? Can you? I cannot.ProgramDevelopers know that code debugging takes much longer than code writing during development. Okay, ncodegenerate provides the debugging function. Today, we will briefly t
