首先是获取特定进程对象,可以使用Process.GetProcesses()方法来获取系统中运行的所有进程,或者使用Process.GetCurrentProcess()方法来获取当前程序所对应的进程对象。当有了进程对象后,可以通过进程对象名称来创建PerformanceCounter类型对象,通过设定PerformanceCounter构造函数的参数实现

Obviously, when Pylance is turned on, more white icon Python processes will appear, and CPU continue to be highly occupied, but these white icon Python processes can all be manually terminated. Regardless of whether Pylance is enabled or not, the white icon Python processes those hardly occupy ...
① psutil (python system and process utilities) 是一个跨平台的第三方库,能够轻松实现获取系统运行的进程和系统利用率(包扩CPU、内存、磁盘、网络等)信息。 ② psutil 主要用于系统监控、分析、限制系统资源和进程的管理。 ③ psutil 库实现了同等命令行工具提供的功能,如ps、top、lsof、netstat、ifconfig、who、...

1. CPU资源浪费,可能鼠标点击的频率非常小,但是扫描线程还是会一直循环检测,这会造成很多的CPU资源浪费;如果扫描鼠标点击的接口是阻塞的呢? 2. 如果是堵塞的,又会出现下面这样的问题,如果我们不但要扫描鼠标点击,还要扫描键盘是否按下,由于扫描鼠标时被堵塞了,那么可能永远不会去扫描键盘; ...
