php-xhprof安装-使用

介绍

官网的我直接拿过来了

XHProf 是一个轻量级的分层性能测量分析器。 在数据收集阶段，它跟踪调用次数与测量数据，展示程序动态调用的弧线图。 它在报告、后期处理阶段计算了独占的性能度量，例如运行经过的时间、CPU 计算时间和内存开销。 函数性能报告可以由调用者和被调用者终止。 在数据搜集阶段 XHProf 通过调用图的循环来检测递归函数，通过赋予唯一的深度名称来避免递归调用的循环。

XHProf 包含了一个基于 HTML 的简单用户界面(由 PHP 写成)。 基于浏览器的用户界面使得浏览、分享性能数据结果更加简单方便。 同时也支持查看调用图。

XHProf 的报告对理解代码执行结构常常很有帮助。 比如此分层报告可用于确定在哪个调用链里调用了某个函数。

XHProf 对两次运行进行比较（又名 “diff” 报告），或者多次运行数据的合计。 对比、合并报告，很像针对单次运行的“平式视图”性能报告，就像“分层式视图”的性能报告

安装

安装xhprof

下载地址：https://pecl.php.net/package/xhprof

----------------------------------------------------------------------
Libraries have been installed in:
   /tmp/pear/temp/pear-build-defaultuserFBmoKa/xhprof-0.9.4/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

编辑加载的文件

vi /usr/local/etc/php/php.ini

添加配置

extension=xhprof.so
xhprof.output_dir=”/data/xhprof/xhprof_data“

xhprof.output_dir string
储存 XHProf 运行数据的默认目录，用于接口 iXHProfRuns(即 XHProfRuns_Default 类)。

验证

/var/www/html # php --ri xhprof

xhprof

xhprof => 0.9.2
CPU num => 2

配置

安装完后/usr/local/lib/php/目录下会有两个目录 xhprof_lib,xhprof_html/ xhprof_lib为工具的依赖目录，xhprof_html为web展示的项目目录，把xhprof_html 配置在Nginx server下 可以通过web地址的形式的方式访问

cp -r /usr/local/lib/php/xhprof_html/ /data/xhprof/
cp -r /usr/local/lib/php/xhprof_lib/ /data/xhprof/

Nginx配置

server{
    server_name mydata.cn;
    listen 80;
    root /data;
    index       index.php;
    autoindex on;
    location / {
            try_files $uri $uri/ /index.php$is_args$args;
    }
    location ~ \.php$ {
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_pass php5-4-33-fpm:9000;
            try_files $uri =404;
    }
}

测试

编辑一个PHP文件测试

<?php
xhprof_enable(XHPROF_FLAGS_CPU + XHPROF_FLAGS_MEMORY);

for ($i = 0; $i <= 1000; $i++) {
    $a = $i * $i;
}

$xhprof_data = xhprof_disable();

$XHPROF_ROOT = "./xhprof/";
include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_lib.php";
include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_runs.php";

$xhprof_runs = new XHProfRuns_Default();
$run_id = $xhprof_runs->save_run($xhprof_data, "xhprof_testing");

echo "<a href='http://mydata.cn/xhprof/xhprof_html/index.php?run={$run_id}&source=xhprof_testing'>goto</a>:http://mydata.cn/xhprof/xhprof_html/index.php?run={$run_id}&source=xhprof_testing\n";

问题记录

在运行过程中php-fpm老是退出重启

[23-Jul-2021 08:42:33] WARNING: [pool www] child 31 exited on signal 11 (SIGSEGV) after 235.186179 seconds from start
[23-Jul-2021 08:42:33] NOTICE: [pool www] child 35 started

解决方案参考
这是一个已知问题，请参阅xhprof 问题
#45和PHP 错误 #67997。

没有官方修复，该项目似乎处于非活动状态，4 年多没有发布。

然而，你可以通过调用变通办法，xhprof_enable()以XHPROF_FLAGS_NO_BUILTINS：

xhprof_enable(XHPROF_FLAGS_NO_BUILTINS);

xhprof_enable(XHPROF_FLAGS_CPU + XHPROF_FLAGS_MEMORY);

改为

xhprof_enable(XHPROF_FLAGS_NO_BUILTINS);

分析

文件格式

运行完测试文件PHP会根据扩展配置的xhprof.output_dir将分析结果生产到指定的目录,文件如下

/data/xhprof # ls xhprof_data/
60fa70ba8140e.xhprof_testing.xhprof

文件名称组成格式:
唯一值.类型.xhprof
文件名称可以由save_run函数改变

 public function save_run($xhprof_data, $type, $run_id = null)

run_id参数不指定，默认用uniqid函数生产一个基于微秒的唯一id

总体报告

根据goto链接来到结果页面，可以看到一个总体报告，里面统计了总的耗时、以及内存的使用情况

Overall Summary	
Total Incl. Wall Time (microsec):	218 microsecs //执行后总共用的时间 单位(微秒)
Total Incl. CPU (microsecs):	0 microsecs // 执行后CPU占用的时间(微秒)
Total Incl. MemUse (bytes):	2,144 bytes //执行后不包含内部函数所占内存占用的容量
Total Incl. PeakMemUse (bytes):	0 bytes //执行后包含内部函数占用内存的容量
