Introduction
When troubleshooting PHP-FPM, it may be required to determine how many processes are active for an account. You can use this procedure to determine if an account is using the max children for PHP-FPM pools.
Procedure
Log in to the SSH/Terminal as the root user. After successfully logged in, run the below commands to gather information about the processes.
To view the PHP-FPM processes of any account:
( Note: replace $cPusername with your account username )
ps -f -U $cPusername |grep "[p]hp-fpm"
To count the PHP-FPM processes of any account:
( Note: replace $cPusername with your account username )
ps -f -U $cPusername|grep -c "[p]hp-fpm"
To view the PHP-FPM processes for all accounts:
for user in `cat /etc/trueuserdomains|awk '{print $2}'`;
do printf "User $user PHP-FPM processes:\n\n";
ps -f -U $user -u $user|grep "[p]hp-fpm";done
To count the PHP-FPM processes for all accounts:
for user in `cat /etc/trueuserdomains|awk '{print $2}'`;
do printf "User $user PHP-FPM processes:\n\n";
ps -f -U $user -u $user|grep -c "[p]hp-fpm";done
If you have a more specific issue with PHP-FPM processes, it would be best to review the article below for tuning PHP-FPM.
