Access php status information from inside php - php

Question

php-fpm provides a status page for those who are interested. It looks like this:
curl http://localhost/server-status
pool: default
process manager: dynamic
start time: 11/Dec/2014:17:51:33 -0500
start since: 61383
accepted conn: 4682
listen queue: 0
max listen queue: 0
listen queue len: 0
idle processes: 11
active processes: 1
total processes: 12
max active processes: 2
max children reached: 0
slow requests: 3
How do I access this information from php? Please don't tell me to use curl to request the status page from localhost.

Answer 1

Unfortunately server-status from FPM is not PHP mechanism. You cannot get it by internal PHP mechanisms.
Your only way to reach this is using some kind of connect mechanism to fpm server itself.
You can get it by grabbing info from url with CURL or file_get_contents() or any other mechanisms that fetches data from url.
You can connect local socket with shell exec using parameters like:
(shell code)
SCRIPT_NAME=/status \
SCRIPT_FILENAME=/status \
REQUEST_METHOD=GET \
cgi-fcgi -bind -connect /var/run/php-fpm/www.sock
You can use some kind of variation of socket connecting with parameters. I haven't tried that, but a good place to start is here: https://github.com/wizaplace/php-fpm-status-cli
Probably if you get very stubborn you can find another creative way, but either of them are doing it as internal mechanism of PHP-FPM.

Answer 2

In ubuntu I was able to access PHP-FPM status page by this
SCRIPT_NAME=/status SCRIPT_FILENAME=/status REQUEST_METHOD=GET cgi-fcgi -bind -connect /var/run/php/php7.0-fpm.sock
Note: You may get not found error while running above command, like
Primary script unknown
Status: 404 Not Found
Content-type: text/html; charset=UTF-8
File not found.
If you are getting this error make sure you have uncommented pm.status_path = /status in pool.d/www.conf.
Absolute path for that config file in ubuntu 17.04 with PHP 7 is /etc/php/7.0/fpm/pool.d/www.conf and line number is 232
After editing conf file restart fpm with service php7.0-fpm restart
GETTING IT VIA PHP SCRIPT
You can get output of php-fpm status by running above command via php with exec()
exec( 'SCRIPT_NAME=/status SCRIPT_FILENAME=/status REQUEST_METHOD=GET cgi-fcgi -bind -connect /var/run/php/php7.0-fpm.sock', $php_fpm_status );
// Above statement will assign an array to $php_fpm_status filled with every line of output from the command, make it as whole string
$php_fpm_status = implode(PHP_EOL, $php_fpm_status);
// You can try printing php-fpm status
echo $php_fpm_status;
