Enable slow log slowlog for nginx php-fpm

The php-fpm slow log slowlog setting allows us to see which php processes are too slow to cause website problems.

We can easily find the problem.

The code is as follows:

Copy code

Vi/data1/server/php-cgi/etc/php-fpm.conf   ; The log file for slow requests ; Default Value: not set ; Note: slowlog is mandatory if request_slowlog_timeout is set Slowlog =/data1/log/$ pool. log. slow   ; 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: 0 Request_slowlog_timeout = 1 s

Both request_slowlog_timeout 0s must be set to disable, that is, slowlog is useless.

1 s indicates that processing in more than 1 s will be recorded.

How many seconds is the execution slow?

The code is as follows:	Copy code
/Data1/server/php-cgi/var/log/php-fpm.log [19-Apr-2013 12:40:35] WARNING: [pool www] child 29514, script'/xx/www/adx/tx/tm. php '(request: "GET/tx/tm. php ") executing too slow (1.034708 sec), logging

Add the slow log tutorial for different php versions.

PHP versions earlier than 5.3.3 are set as follows:

The code is as follows:

Copy code

The timeout (in seconds) for serving a single request after which the worker process will be terminated Shocould be used when 'max _ execution_time 'ini option does not stop script execution for some reason '0s' means 'off' <Value name = "request_terminate_timeout"> 10 s </value> The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow. log file '0s' means 'off' <Value name = "request_slowlog_timeout"> 1 s </value> The log file for slow requests <Value name = "slowlog"> logs/slow. log </value>

PHP 5.3.3 and later versions are set as follows:

The code is as follows:

Copy code

; 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: 0 Request_slowlog_timeout = 1 s ; The log file for slow requests ; Default Value:/usr/local/php/log/php-fpm.log.slow Slowlog =/usr/local/php/log/php-fpm.log.slow ; The timeout for serving a single request after which the worker process will ; Be killed. This option shocould be used when the 'max _ execution_time 'ini option ; Does not stop script execution for some reason. A value of '0' means 'off '. ; Available units: s (econds) (default), m (inutes), h (ours), or d (ays) ; Default Value: 0 Request_terminate_timeout = 10 s

Note: request_terminate_timeout terminates a process that has been executed for too long.

Request_slowlog_timeout writes slow files to logs.

Later, you can optimize the program file based on the slow execution log/usr/local/php/logs/slow. log!
