仅使用非常小的资源消耗。

const {node_process_watcher} = require("node-process-watcher");
// or import {node_process_watcher} from "node-process-watcher";
node_process_watcher.on("screen1",(list)=>{
    // Print the information of all processes on the system every second
    // 每秒打印一次系统上所有进程的信息
    console.log(list[0]);
    // { id: 4, user_name: 'SYSTEM', cpu: 0, mem: 0, name: 'System' }
    node_process_watcher.close("screen1"); // 关闭
})
node_process_watcher.on("screen2",(list)=>{
    // Filter specific processes
    // 过滤特定的进程
    node_process_watcher.pids("screen2",[
        list[0].id
    ])
    console.log(list[0]);
    if (list.length === 1) {
        // Stop listening for information only after all the on events are closed
        // 所有的on关闭后才会停止监听信息上的信息
        node_process_watcher.close("screen2");
    }
})
