How to determine which script is being executed in PHP-FPM process
提问by Marki555
I am running nginx + php-fpm. Is there any way how can I know what is each of the PHP processes doing? Something like extended mod_status in apache, where I can see that apache process with PID x is processing URL y. I'm not sure if the PHP process knows the URL, but getting the script path and name will be sufficient.

After some googling hours and browsing PHP.net bug tracking system I have found the solution. It is available since PHP 5.3.8 or 5.3.9, but doesn't seem to be documented. Based on feature request #54577, the status page supports option full, which will display status of each worker separately. So for example the URL will be http://server.com/php-status?fulland sample output looks like:
经过一些谷歌搜索和浏览 PHP.net 错误跟踪系统后，我找到了解决方案。它从 PHP 5.3.8 或 5.3.9 开始可用，但似乎没有记录。基于功能请求#54577，状态页面支持选项full，它将分别显示每个工人的状态。因此，例如 URL 将是http://server.com/php-status?full，示例输出如下所示：
pid: 22816
state: Idle
start time: 22/Feb/2013:15:03:42 +0100
start since: 10933
requests: 28352
request duration: 1392
request method: GET
request URI: /ad.php?zID=597
content length: 0
user: -
script: /home/web/server.com/ad/ad.php
last request cpu: 718.39
last request memory: 1310720

PHP-FPM has a built in status monitor, though it's not as details as mod_status. From the php-fpm config file /etc/php-fpm.d/www.conf(on CentOS 6)
PHP-FPM 有一个内置的状态监视器，虽然它不像 mod_status 那样详细。来自 php-fpm 配置文件/etc/php-fpm.d/www.conf（在 CentOS 6 上）
; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. By default, the status page shows the following
; information:
; accepted conn - the number of request accepted by the pool;
; pool - the name of the pool;
; process manager - static or dynamic;
; idle processes - the number of idle processes;
; active processes - the number of active processes;
; total processes - the number of idle + active processes.
; The values of 'idle processes', 'active processes' and 'total processes' are
; updated each second. The value of 'accepted conn' is updated in real time.
; Example output:
; accepted conn: 12073
; pool: www
; process manager: static
; idle processes: 35
; active processes: 65
; total processes: 100
; By default the status page output is formatted as text/plain. Passing either
; 'html' or 'json' as a query string will return the corresponding output
; syntax. Example:
; http://www.foo.bar/status
; http://www.foo.bar/status?json
; http://www.foo.bar/status?html
; Note: The value must start with a leading slash (/). The value can be
; anything, but it may not be a good idea to use the .php extension or it
; may conflict with a real PHP file.
; Default Value: not set
;pm.status_path = /status
If you enable this, you can then pass the path from nginx to your socket/port for PHP-FPM and you can view the status page.
如果启用此功能，则可以将路径从 nginx 传递到 PHP-FPM 的套接字/端口，并且可以查看状态页面。
nginx.conf:
nginx.conf：
location /status {
include fastcgi_params;
fastcgi_pass unix:/var/lib/php/php-fpm.sock;
}

cgi command line is more convinient:
cgi 命令行更方便：
SCRIPT_NAME=/status \
SCRIPT_FILENAME=/status \
REQUEST_METHOD=GET \
cgi-fcgi -bind -connect 127.0.0.1:9000

You can use strace to show the scripts being run - and many other things - in real time. It's pretty verbose, but it can give you a good overall picture of what's going on:
您可以使用 strace 实时显示正在运行的脚本以及许多其他内容。它非常冗长，但它可以让您对正在发生的事情有一个很好的整体了解：
# switch php-fpm7.0 for process you're using
sudo strace -f $(pidof php-fpm7.0 | sed 's/\([0-9]*\)/\-p /g')
The above will attach to the forked processes of php fpm. Use -pto attach to a particular pid.
以上将附加到 php fpm 的分叉进程。使用-p附加到一个特定的PID。
The above would get the scrip path. To get the urls, you would look at your nginx / apache access logs.
以上将获得脚本路径。要获取 url，您需要查看 nginx/apache 访问日志。
As a side note, to see the syscalls and which ones are taking longest:
作为旁注，要查看系统调用以及哪些耗时最长：
sudo strace -c -f $(pidof php-fpm7.0 | sed 's/\([0-9]*\)/\-p /g')
Wait a while, then hit Ctr-C
稍等片刻，然后按 Ctr-C
