MySQL效能监控工具mysqlreport安装部署及相关收集内容的解释说明

MySQL效能监控工具mysqlreport安装和中文说明管理 mysql 最让人困扰的就是如何有效的掌握 MySQL 的健康状况，因为 MySQL 虽然有提供许多系统变量值供您参考，但这些零散的数据若要手动搜集与过滤将会是一件十分没有效率的事情(除非您写 Scripts 去分析)。而接下来要介绍的这套 “工具” 其实是由 hackmysql.com 的站长所撰写的 perl Scritps，旨在协助 MySQL DBA 搜集与分析 MySQL 的运作状况。官方网站： http://hackmysql.com/软件下载： http://hackmysql.com/mysqlreportmysqlreport以很友好的方式显示MySQL状态变化。事实上，它几乎报告了所有的状态。不像SHOW STATUS 只是在显示了100多个状态值，mysqlreport 则以人性化的方式阐释和格式化了这些状态值，大大增加了其可读性。mysqlreport 的好处是可以快速的查看各种状态参数组，从而了解服务器的运行状态情况，而无需从SHOW STATUS 的结果中人工计算。例如索引读取比率是个重要的参数，但是SHOW STATUS 中并没有显示；它是一个推断值(key_reads和 key_read_requests 的比值)。mysql命令行中经常使用下面的指令来获取当前数据库的实时状态：mysql>show status;mysql>show innodb status;但是他们的显示结果不太友好，我们需要更好的更加人性化的分析结果，而不是堆出来一堆数字。mysqlreport是一个第三方的Mysql状态报告工具，它把mysql的show status 和 show innodb status的结果进行一系列的后期处理，让可读性更强，更友好。 下面是mysqlreport的安装过程：MySQLReport 是用perl语言编写，所以想要运行它首先需要安装perl环境；它还要与MySQL数据库连接，所以还需要安装数据库接口 DBI 和数据库驱动DBD-MySQL 。# perl-v //如果显示perl版本说明perl环境已经安装安装DBIyum -y installperl-DBI或者# wgethttp://www.cpan.org/modules/by-module/DBI/DBI-1.634.tar.gz# tar -zxf DBI-1.634.tar.gz# cd DBI-1.634# perl Makefile.PL# make# make test# make# makeinstall安装DBD-mysql
