Use the slow execution log slowlog of php-fpm to analyze PHP Execution efficiency and program bugs

Enable the slowlog log of php-fpm, view the php file that has been executed for too long, and terminate the process that has been executed for too long! See how it works!

PHP versions earlier than 5.3.3 are set as follows:

      The timeout (in seconds) for serving a single request after which the worker process will be terminated      Should be used when 'max_execution_time' ini option does not stop script execution for some reason      '0s' means 'off'      
 
  10s
       The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow.log file      '0s' means 'off'      
 
  1s
       The log file for slow requests      
 
  logs/slow.log
 

PHP 5.3.3 and later versions are set as follows:

; The timeout for serving a single request after which a PHP backtrace will be; dumped to the 'slowlog' file. A value of '0s' means 'off '.; available units: s (econds) (default), m (inutes), h (ours), or d (ays); Default Value: 0request_slowlog_timeout = 1 s (RunMore than 1 s of php scriptsLogsRecord); The log file for slow requests; Default Value: /usr/local/php/var/log/php-fpm.log.slowslowlog =/usr/local/php/var/log/php-fpm.log.slow (turn on slowRunLogs,LogsThe directory path must exist correctly, otherwise an error will be reported); the timeout for serving a single request after which The worker process will; be killed. this option shoshould be used when the 'max _ execution_time 'ini option; does not stop script execution for some reason.
