直观地分析PHP应用程序的内存使用情况的工具 [英] Tools to visually analyze memory usage of a PHP app
问题描述
是否有任何免费软件或商业软件可以促进PHP应用程序对内存使用情况的分析?我知道xdebug可以生成跟踪文件，该跟踪文件可以通过函数调用显示内存使用情况，但是如果没有图形工具，数据将难以解释.
Is there anything out there freeware or commercial that can facilitate analysis of memory usage by a PHP application? I know xdebug can produce trace files that shows memory usage by function call but without a graphical tool the data is hard to interpret.
理想情况下，我希望不仅可以查看总内存使用情况，而且还可以查看堆中有哪些对象以及类似于
Ideally I would like to be able to view not only total memory usage but also what objects are on the heap and who references them similar to Jprofiler.
推荐答案
您可能已经知道，Xdebug从2. *版本开始就放弃了内存分析支持.请在此处搜索已删除的功能"字符串: http://www.xdebug.org/updates.php
As you probably know, Xdebug dropped the memory profiling support since the 2.* version. Please search for the "removed functions" string here: http://www.xdebug.org/updates.php
已删除功能
删除了对内存配置文件的支持，因为它无法正常工作.
Removed support for Memory profiling as that didn't work properly.
所以我尝试了另一种工具，对我来说效果很好.
So I've tried another tool and it worked well for me.

这是我在Ubuntu服务器上为启用它所做的事情:
This is what I've done on my Ubuntu server to enable it:
sudo apt-get install libjudy-dev libjudydebian1
sudo pecl install memprof
echo "extension=memprof.so" > /etc/php5/mods-available/memprof.ini
sudo php5enmod memprof
service apache2 restart
然后在我的代码中:
<?php
memprof_enable();
// do your stuff
memprof_dump_callgrind(fopen("/tmp/callgrind.out", "w"));
最后使用 KCachegrind
首先通过在此处下载最新的软件包来安装 Google gperftools : https://code.google.com/p/gperftools/
First of all install the Google gperftools by downloading the latest package here: https://code.google.com/p/gperftools/
然后一如既往:
sudo apt-get update
sudo apt-get install libunwind-dev -y
./configure
make
make install
现在输入您的代码:
memprof_enable();
// do your magic
memprof_dump_pprof(fopen("/tmp/profile.heap", "w"));
然后打开您的终端并启动:
Then open your terminal and launch:
pprof --web /tmp/profile.heap
pprof 将在您现有的浏览器会话中创建一个新窗口，如下所示:
pprof will create a new window in your existing browser session with something like shown below:
使用 Xhprof 和 Xhgui ，您还可以分析cpu的使用情况，也可以仅分析内存使用情况(如果这是当前的问题). 这是一个非常完整的解决方案，它使您可以完全控制，并且日志可以写在mongo或文件系统中.
With Xhprof and Xhgui you can profile the cpu usage as well or just the memory usage if that's your issue at the moment. It's a very complete solutions, it gives you full control and the logs can be written both on mongo or in the filesystem.

如果您使用 puphpet 来设置您的虚拟机，您将很高兴知道它的支持；-)
If you use puphpet to set up your virtual machine you'll be happy to know it's supported ;-)
