扩展功能，预计 2.2.x 版本完成开发合并

暂时简单部署模式下考虑文件写入 /tmp 目录缓存

数据库方案作为线下定制化方案执行

由于计划接入 heap profiler，heapsnapshot 多次对比分析意义不大，排出计划

预计 2.2.x 版本开发完毕，参考 mat，给出疑似泄漏点更加精确

v2.1.5:

• 增加了虚拟路径转发的功能，文档增加对应的 虚拟路径转发 功能说明

全新重构的 2.0 已经发布: Demo & Document

使用有问题可以 issue 反馈，快速响应

看了下，是v8-profiler的问题，它这些issues还未修复，那如何安装这个包呢？

选择cpu + 子进程 无法进入分析页面。
如果不选择cpu的话，正常

下面是后台报错：

如果有时间的话，能否定位一下问题出在哪？
多谢。

长期工作，提供在线解析 core dump 文件的能力。堆栈异常 + 内存泄漏的比较终极的解决方案了

内存泄漏分析功能增强，预计 2.2.x 版本开发合并
难点在于 v8 的 heap-profiler 数据序列化和导出，目前有两种思路：

封装 inspector，低版本不支持
重写 v8-profiler-next，重写序列化，全版本支持

思考 ing...

这是什么原因？

您好,我想问一上是否支持这个功能,我选择解析类型为OS,出来是实时的,但那个出来的坐标不太明白是什么意思,这个500的单位如果是M的话,为什么就是500了?单机不应该是1.4G?希望解答一下

计划于 2.2.x 完成开发和合入

一期：UI部分采用 vue.js 重构
二期：后台部分处理逻辑彻底重构
三期：提供集群部署功能

附：ReadME重写

用MEM检查内存的时候，浏览器会卡在“Memory Stream 准备完毕，即将开启子进程进行流式读取，此过程较慢，请耐心等待...”，cmd报错common.socket->onData error: TypeError: Cannot read property 'on' of null。
请问这个问题该怎么排查。

Load all heapsnapshot to memory will cause child_process memory explosion, so it will be changed as stream

下载了最新的2.2.0版本，发现CPU页面以前可以点击的火焰图顶部的几个文字按钮还在但是无法点击了

更加友好的 flame chart 展示
https://www.npmjs.com/package/flamegraph

os可以，选择cpu或者mem就返回这个
{"success":false,"code":3,"error":"服务器内部错误!"}
求解……

v2.1.1:

• 优化了文档说明
• 修正一处在开启第三方缓存模式下动态修改鉴权信息的 bug
• CPU Profiling 结果解析算法优化，极大提升速度

node版本:v8.4.0
选择 CPU和mem监控的时候 出现如下错误
[Easy-Monitor: dashboard <10448>] http.axios.profiler error: TypeError: Cannot read property 'composeKey' of undefined
[Easy-Monitor: dashboard <10448>] http.axios.profiler error: TypeError: Cannot read property 'composeKey' of undefined

[Easy-Monitor: dashboard <10448>] http.axios.profiler error: TypeError: Cannot read property 'composeKey' of undefined

v2.1.3:

• 修正了开启子进程处理数据在 Node v6.4.0 及以下版本不支持的问题
• 修正了开启计算的子进程内存溢出后导致主进程 WRITE EPIPE 的错误
• 优化了 MEM 分析部分搜索任意节点的功能，如下：
  • 搜索任意节点一栏移至最上方
  • 展示由引力图更改为详细的树结构展示
  • 搜索逻辑更改为支持从 root 节点出发的限定深度内的所有节点
• 优化了负责数据解析的子进程启动参数，以能够处理更大的 HeapSnapshot
• 优化了 CPU & Memory 分析期间的中间态错误提示

[Easy-Monitor] <common.profiler.js> load error: Error: Cannot find module './bui
ld/profiler/v5.7.6/node-v57-win32-x64/profiler.node'

fix some bugs
add readme_zh

由于正式服务器开放的端口有限, easymonitor 的 web 页面可以增加虚拟目录吗? 以便实现 path 转发

部署在阿里云上
http://114.55.8.96:12333/index

axiosProfilerDetail返回数据：{"success":false,"code":3,"error":"服务器内部错误!"}

目前重构基本已经完成
但是因为 v8-profiler 在 Node 8 下做堆快照导出有Bug，故还未正式升级放出，有兴趣的可以执行：

npm install easy-monitor@[email protected]

注意：Node 8 下配套的 npm 不再支持 tag，故 Node 8 用户需要如下安装：

npm install [email protected]

体验一下新版本，大致用法没有变化，新版本的文档还在撰写中，预计等 v8-profiler 在 Node 8 下的 Bug 修掉后放出正式升级~

最后有问题可以在这里提 issue，新版本兼容 Node v4 ~ Node v6

请问浅引用和保留引用分别指的是什么

预计 2.2.x 开发合并

类似这样的log
配置为一个dashboard,独立运行没任何内容:

   easyMonitor({
        cluster: true,
        bootstrap: 'dashboard',
        dashboard: {
            port_http: 12333,
            port_tcp: 22333
        }
    });

然后每个需要监控的进程使用如下配置:

        easyMonitor({
            cluster: true,
            bootstrap: 'embrace',
            project_name: 'myproj_' + id,
            embrace: {

                tcp_port: 22333,
            },
        });

最后会出现无法查看的情况,最多只能查看一个节点
使用childprocess.spawn来创建

问题可能是你所引用的abbrev出现问题。
npm install 可以正常安装
yarn add 是失败的，错误信息如下：

error An unexpected error occurred: "EINVAL: invalid argument, lstat '/mnt/c/Web/hrm_api/node_modules/abbrev/package.json'".

需要更详细的情况，请联系我

v2.1.2:

• 修正了默认部署模式下开启 inspect 或 debug 调试时无法启动的问题
• 修正了新的 CPU Profiling 算法下的计算调用者百分比的错误，页面增加了调用者函数名称的展示
• 增加了通知子进程进行操作时的超时判定
• 增加了配置长时间采集 CPU 数据时的中间态友好提示：总耗费 xxx 时长，剩余时间 xxx 时长
• 增加了采集 CPU/Memory 数据分析支持开启子进程分析，减小对业务进程计算压力（可动态更改）

开始客户端 UI 重构

这是我写的内存泄露测试代码

let theThing = null
    let replaceThing = function () {
        let leak = theThing
        let unuse = function () {
            if (leak) console.log('hi')
        }
        theThing = {
            longStr: new Array(1000000).join('*'),
            someMethod: function () {
                if(leak) 
                console.log('a')
            }
        }
    }
    router.get('/leak', async ctx => {
        replaceThing()
        ctx.body = '内存泄露测试'
    })

反复访问/leak接口。
然后打开监控页面提示有内存泄露。点击泄露节点打开引力图。发现泄露链的信息没有相关关键词，如下：

I. 泄漏链: ::@117359.context --> system / Context::@117357.this --> Router::@130443._switcher --> Switcher::@130447._cases --> Array::@144155.[1] --> Object::@117353.result --> Switcher::@117355._cases --> Array::@144333


II. 泄漏关键字: context, this, _switcher, _cases, [1], result

本来应该是有theThing, someMethod这种关键词的。
node版本：8.9.1。easy-monitor版本：2.2.1

求大佬解惑！

你好，我用的是node8.2版本 安装总报错 按照之前的问题安装过windows下面的工具了，但还是安装出错。
