Use mod_log_slow slow response request targeting apache

Why 80% of the code can not do farming architect? >>>  

apache + php site load time to time high load, but because of the above sites too much, too difficult to troubleshoot in the end is what caused the site. nginx + php-fpm'd better check, he had a slowlog, you can quickly navigate to the location of php code failure, use xdebug to look into the problem is too complex. Write mod_log_slow inspired by the mysql slowlog. The following translation of the official. 1. compile and install mod_log_slow 1) extracting

tar zxf mod_log_slow-1.0.7.tar.gz
cd mod_log_slow

git clone git://github.com/yokawasa/mod_log_slow.git
cd mod_log_slow

2) Open Makefile and modify variables ap_basedir

#vi Makefile
 ap_basedir=/改成你的apache安装路径
# make
# make install

    CustomLog logs/transfer_log "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" \"%{logslow-id}n\" \"%{logslow-time}n\""

    ## (VirtualHost) mod_log_slow configuration
    LogSlowEnabled On
    LogSlowLongRequestTime 100
    LogSlowFileName /usr/local/apache/logs/slow_log
    LogSlowTimeFormat "[%Y-%m-%d %H:%M:%S]"
