找到哪个函数（文件）导致服务器重载 [英] find which function(file) causes server overload

问题描述

我已阅读 此主题 ，但是我的主题不重复。

I have read this topic, but my topic is not duplicate.

如果我有一个特定的帮助函数/方法，它将会很好的跟踪所有进一步的功能，在PHP中执行，以确定每个函数的执行时间，如下所示：

It will be excellent, if I had an specific helper function/method, which will track all further functions, which are being executed in PHP, to determine the each function's execution time, like this:

executed URL: /mypage.php
function execution times:
        initialize(): 1.2 seconds
         - cookie_checker(): 0.1 ms
           -- set_cookie():  0.01 ms 
           -- blabla():  0.5 ms
         - start_authorization(): 0.27 ms
        page_output(): 2.4 seconds
         - header_output(): 0.3 ms
           -- XXXXXXXXXXXXX():  0.01 ms 
           -- YYYYYYYYYYYYY():  0.5 ms
         - ZZZZZZZZZZZZZ(): 0.27 ms

所以，我会有日志，找出哪些功能导致se rver / CPU过载。有任何想法如何实现这一点？

so, i will have logs and find out which function causes server/CPU overload. Have you any ideas how to achieve this?
