php慢日志

php开启慢日志

修改php-fpm.conf

; - 'slowlog'
; The log file for slow requests
; Note: slowlog is mandatory if request_slowlog_timeout is set
slowlog = /var/logs/php/$pool.log.slow
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
request_slowlog_timeout = 1

日志说明

script_filename 是入口文件，执行方法超过执行时间 调用路径

[21-Sep-2016 14:49:34]  [pool www] pid 22263
script_filename = /data/web/public/index.php
[0x00007fe3d8a9c070] fastcgi_finish_request() /data/web/bootstrap/cache/compiled.php:16014
[0x00007fe3d8a9bf40] send() /data/web/public/index.php:56
