测量和监视Node.JS服务器性能 [英] Measuring and monitoring Node.JS server performance
问题描述
我是Node.JS的新手，已经在Google上搜索了Aswer，但是有很多方法可以做到这一点. 您是否需要某种数学知识才能知道何时需要扩展Node.JS服务器?以及用于监视服务器性能和错误跟踪的工具是什么?
I'm new to Node.JS, already Googled for aswers but there is a lot of ways of doing this. Do you have some sort of math to know when I'll need to scale my Node.JS server? And what tools you use for monitoring server performance and error track?
谢谢！
推荐答案
正如@ThiefMaster所说，这取决于您的系统.您需要监视对站点的请求，CPU负载，内存占用等，并确定是否以及何时添加模式服务器.
As @ThiefMaster said, this depends on your system. You need to monitor the requests for your site, the CPU load, memory footprint etc and decide if and when to add mode servers.
