phpfpm uses its own status optimization steps

php-fpm has a built-in status page like nginx, which is very helpful for understanding the status of php-fpm and monitoring php-fpm. For subsequent zabbix monitoring, we need to first understand what the php-fpm status page is.

1. Enable php-fpm status function

<code><span># cat  /usr/local/php-5.5.10/etc/php-fpm.conf | grep status_path</span>
pm.status_path = /status</code>

2. nginx configuration

<code>server {
    listen  *:<span>80</span> default_server;
    server_name _;
    location ~ ^/(status|ping)$
    {
        <span><strong>include</strong></span> fastcgi_params;
        fastcgi_pass <span>127.0</span><span>.0</span><span>.1</span>:<span>9000</span>;
        fastcgi_param SCRIPT_FILENAME <span>$fastcgi_script_name</span>;
    }
}</code>

3. Restart nginx/php-fpm

<code>service nginx restart
service php<span>-fpm</span> restart</code>

4. Open the status page

<code><span># curl http://www.ttlsa.com/status</span>
pool:                 www
process manager:      dynamic
start time:           <span>14</span>/May/<span>2014</span>:<span>22</span>:<span>40</span>:<span>15</span> +<span>0800</span>
start since:          <span>58508</span>
accepted conn:        <span>33</span>
listen queue:         <span>0</span>
max listen queue:     <span>8</span>
listen queue len:     <span>0</span>
idle processes:       <span>2</span>
active processes:     <span>1</span>
total processes:      <span>3</span>
max active processes: <span>5</span>
max children reached: <span>0</span>
slow requests:        <span>2091</span></code>

5. Detailed explanation of php-fpm status

• pool – fpm pool name, mostly www
  process manager – process management method, value: static, dynamic or ondemand. dynamic
  start time – start date, if php-fpm is reloaded, the time will be updated
  start since – running time
  accepted conn – the number of requests accepted by the current pool
  listen queue – request waiting<strong>queue</strong>, if this value is not 0, then increase the number of FPM processes
  max listen queue – the highest number of requests waiting in the queue listen queue len – socket waiting queue
  length idle processes – number of idle processes active processes – Number of active processes
  total processes – total number of processes
  max active processes - the maximum number of active processes (counted after FPM starts)
  
  max children reached
  - The number of times the maximum number of processes is limited. If this number is not 0, it means that your maximum number of processes is too small, please Make it bigger. slow requests – php-fpm slow-log is enabled, the number of slow requests
  
6. Other parameters of php-fpm

One of the more personalized aspects of the php-fpm status page is that it can take parameters, it can take parameters

json

, xml, html and the first three parameters can be combined with full respectively.

6.1 json

6.5 full detailed explanation

• pid – Process PID, you can kill this process alone. You can use this PID to kill a long running process.
state – the state of the current process (Idle, Running, …)
• start time – the date the process started
  start since – how long the current process has been running
  requests – How many requests have been processed by the current process
  request duration – request duration (subtle)
  request method – request method (GET, POST, …)
  request URI – request URI
  content length – request content length (only for POST)
  user – user (PHP_AUTH_USER) (or ‘-’ if not set)
  script – PHP script (or ‘-’ if not set)
  last request cpu – Last request CPU usage.
  last request memorythe - the memory used by the last request
  
  
7. Complete

php-fpm status page is very useful. When using zabbix or nagios monitoring, you can consider using xml or the default method. If you use the web, it is recommended to use html, the table will be clearer.

The above introduces the steps for phpfpm to use its own status optimization, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
