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 poollisten 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.

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.
