MySQL监控工具-orzdba
源代码地址：http://code.taobao.org/p/orzdba/src/trunk/
[root@linuxidc servers]# chmod +x orzdba
在代码的160行左右，配置自己的MySQL验证信息：username、password、socket、host、port
[root@linuxidc servers]# grep -n 'my $MYSQL' orzdba
160:my $MYSQL = qq{mysql -s --skip-column-names -uroot -pyoon -h127.0.0.1 -P$port };
先安装tcprstat
[root@linuxidc servers]# ln -sf /export/servers/tcprstat-static.v0.3.1.x86_64 /usr/bin/tcprstat
[root@linuxidc servers]#chmod u+s /usr/bin/tcprstat
需要安装的perl依赖包：
yum install perl-Test-Simple.x86_64
yum install perl-Time-HiRes
yum install perl-ExtUtils-CBuilder
yum install perl-ExtUtils-MakeMaker
yum install perl-DBD-MySQL
yum install perl-DBI
安装中报错：（因缺少了“yum install perl-Test-Simple.x86_64”）

安装Perl的File：LockFfile模块
安装version模块
wget http://search.cpan.org/CPAN/authors/id/J/JP/JPEACOCK/version-0.99.tar.gz
tar -zxvf version-0.99.tar.gz
cd version-0.99
perl Makefile.PL
make
make test
make install
安装安装File::Lockfile模块：
wget http://search.cpan.org/CPAN/authors/id/G/GL/GLORYBOX/File-Lockfile-v1.0.5.tar.gz
tar -zxvf File-Lockfile-v1.0.5.tar.gz
cd File-Lockfile-v1.0.5
perl Build.PL
perl ./Build
perl ./Build test
perl ./Build install
安装Class-Data-Inheritable模块：
wget http://search.cpan.org/CPAN/authors/id/T/TM/TMTM/Class-Data-Inheritable-0.08.tar.gztar -zxvf Class-Data-Inheritable-0.08.tar.gz
cd Class-Data-Inheritable-0.08
perl Makefile.PL
make
make test
make install
安装Module-Build模块：
wget http://search.cpan.org/CPAN/authors/id/K/KW/KWILLIAMS/Module-Build-0.31.tar.gz
tar -zxvf Module-Build-0.31.tar.gz
cd Module-Build-0.31
perl Build.PL
./Build
./Build test
./Build install
安装完提示：Usage: Socket::inet_ntoa(ip_address_sv) at ./orz line 477
因主机名不能解析，将IP和主机名写到/etc/hosts文件
[root@linuxidc servers]# vi /etc/hosts
172.16.9.242 linuxidc.com
[root@linuxidc servers]# ./orzdba -lazy -rt -S /export/data/mysql/tmp/mysql.sock
count：此间隔内完成的请求数量
avg：此间隔内所有完成的请求，响应的平均时间
95_avg：此间隔内，95%的请求量的平均响应时间，单位微秒，该值较能体现MySQL Server查询的平均响应时间
[root@linuxidc servers]# ./orzdba -innodb -S /export/data/mysql/tmp/mysql.sock
