View and monitor the running status of PHP-FPM in real time

PHP-FPM has a built-in status page. After opening it, you can view the detailed running status of PHP-FPM, which will help PHP-FPM optimization. The following article will record how to view and monitor the running status of php-fpm in real time.

Open php-fpm.conf and configure the php-fpm status page options

pm.status_path = /phpfpm_status (default value is: status)

Configure nginx.conf and add an accessible server (does not need to be placed in http)

server {
                              listen 80; cgi_params; -fpm, the command is as follows:

service php-fpm restart
service nginx restart

The browser access result is as shown below:

In addition, you can view the php-fpm status output format with different parameters:

http:/ /www.phpernote.com/status #Default plain text

http://www.phpernote.com/status?json #json format

http://www.phpernote.com/status?html #html format

http:/ /www.phpernote.com/status?xml #xml format

You can also view process details by using the full parameter:

http://www.phpernote.com/status?full

http://www.phpernote. com/status?json&full

http://www.phpernote.com/status?html&full
http://www.phpernote.com/status?xml&full

The following is a detailed description of the PHP-FPM status parameters:

start time – Start date, if php-fpm is reloaded, the time will be updated

start since – Running time

accepted conn – the number of requests currently accepted by the pool

listen queue – the request waiting queue, if this value is not 0, then increase the number of FPM processes

max listen queue – the highest number of request waiting queues

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 – maximum number of active processes (calculated from FPM startup)

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 change it to a larger number.

slow requests – With php-fpm slow-log enabled, the number of slow requests

The above introduces the real-time viewing and monitoring of the running status of PHP-FPM, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
