 Description   

Steps to reproduce:

  1. Use the PHP-FPM by Zabbix agent template
  2. PHP-FPM: Number of processes running returns no processes

[bug report] PHP-FPM: Process is not running - ZABBIX Forums

Result:
Returns 0 when PHP-FPM processes are running
Expected:
Returns number of PHP-FPM processes running

Fix:

update PHP-FPM templates as follows

1. Add a new macro to the template

the user is typically www-data but do ps -ef|grep php-fpm to confirm

Macro: {$PHP_FPM.USER}
Value: www-data

2. Update existing Item "PHP-FPM: Number of processes running" key
from
Code:
proc.num["\{$PHP_FPM.PROCESS_NAME}"]
to:
Code:
proc.num[,"\{$PHP_FPM.USER}",,"\{$PHP_FPM.PROCESS_NAME}"]

I have uploaded the edited template from zabbix 6.0.7 that will hopfully help.

The reason behind this is that the actual process names may differ, depending on used OS distribution. E.g Debian/Ubuntu - php-fpm7.4, php-fpm8.1; RHEL-like - php-fpm. Same for Apache (DEB - apache2, RPM - httpd). Actual process name can be found in line "Name" of /proc/<pid>/status file (10 Notes on selecting processes in proc.mem and proc.num items (zabbix.com)).

The proposed solution doesn't take the master process into account (the user is root and not www-data/apache).

The issue will be resolved for 6.2 and upcoming 6.4 in ZBXNEXT-7924 Switch templates to proc.get - ZABBIX SUPPORT , which will allow to discover processes by their names using regex.

For 5.0 and 6.0 notes about actual process names depending on OS distribution were added.
