帮忙分析下NODEJS 线上性能日志!
发布于 6 个月前 作者 xulayen 1268 次浏览 来自 分享

压测NODEJS(PM2管理的负载)接口之后,随便点击任意一个接口出现CPU暴涨到100%+,不点击之后恢复10%(压测之前CPU只有0.3%左右),再次点击又暴涨到100%+ 只有杀掉NODE进程,重启站点才正常。这是通过node --prof-process分析出来的日志

Statistical profiling result from isolate-0x3f09b30-v8.log, (1097 ticks, 7 unaccounted, 0 excluded).

从日志看,CPU消耗主要集中在shared_librarys,这部分占比达到80%,shared_librarys中node的消耗占比最大,达到70%。两个比例相乘,可以看出node程序占总的CPU消耗达到56%。我再尝试分析下,暂时先记录下来。

从Node的分析: 265 36.6% LazyCompile: ~Script vm.js:44:14 265 100.0% LazyCompile: ~createScript vm.js:273:22 265 100.0% LazyCompile: ~runInThisContext vm.js:322:26 265 100.0% LazyCompile: ~Module._compile internal/modules/cjs/loader.js:657:37 可以看出来这段调用栈消耗CPU最高

@linxiaoziruo 谢谢你!,你说的是对的。同时我也用v8开源项目测试分析了一下日志文件得出结论是。每次NODE主程序都在进行编译。我想了一下因为一次偶然的机会我直接把开发环境的.babelrc文件直接发布到生产环境上去了。根本没有进行把es6编译成es5放上去。导致每次程序被访问都会重新编译一遍。所以日志会显示 LazyCompile

另外分享一下我的方法。


node --prof app.js # 执行完找到 isolate-xxxxxxxxxx.log这样的文件,执行下面的命令

node --prof-process --preprocess isolate-xxxxxxxxxx-v8.log > v8.json

git clone https://chromium.googlesource.com/v8/v8.git

打开v8/tools/profview/index.html

选择刚刚执行好的v8.json文件查看堆栈

重新编译打包之后再次测试的v8测试图是。谁能帮我分析下:
