Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

node-process-watcher

A lightweight real-time monitoring system for all process information. 轻量级的实时监控系统上所有的进程信息。

Example

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");
    }
})

说明

对于进程的内存信息,在windows下采集的是工作集(wss)大小(一段时间内进程所需要的内存页集合大小),在Linux下采集的是(rss)物理常驻集大小,表示所占用的所有物理上的内存大小包括共享内存。

支持环境

  1. linux ✅ Yes
  2. windows ✅ Yes
  3. mac 🟨 Not 目前在mac 无法安装(没有测试过)。本项目使用了预构建,建议使用Node18,不需要编译而是从github下载编译好的文件,如果你电脑上的网络安装的时候无法访问github则会退化成编译。在windows上编译可能遇到的问题可以参考这个链接https://blog.csdn.net/jjocwc/article/details/134152602。
