教你使用PHP-FPM的slow log分析网站2014-08-04 iteye eimhee最近从GOOGLE ananlytics 发现网站速度变慢了很多,于是想到了PHP中的FPM慢日志功能。好在 PHP-FPM 提供了慢执行日志,可以将执行比较慢的脚本的调用过程 dump 到日志中。Shell代码cd /etc/php5/fpm/pool.d/vi www.conf修改配置Java代码
; 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 = 1s; The log file for slow requests; Default Value: /usr/local/php/log/php-fpm.log.slowslowlog = /usr/local/php/log/php-fpm.log.slow
加上慢执行日志后,我们可以很容易从慢执行日志中看出问题所在,比如:Log代码

再进行进一步的程序分析,就更具方向性了。
