安装 orzdba
代码SVN地址:http://code.taobao.org/p/orzdba/src/trunk/
说明:Perl脚本,用于对Linux主机和MySQL相关指标进行实时监控。
修改代码160行左右配置MySQL的相关验证信息,如username,password,host,port,sock等
安装tcprstat
安装orzdba_rt_depend_perl_module.tar.gz依赖包(version模块、Class-Data-Inheritable模块、Module-Build模块、File-Lockfile模块)
shell> grep -n 'my $MYSQL' orzdba
160:my $MYSQL= qq{mysql -s --skip-column-names -uroot -P$port };
shell> chmod +x orzdba
shell> ./orzdba --help

-sys:打印系统信息,包括-t(打印当前时间)、-l(打印负载信息,分1分钟、5分钟、15分钟)、-c(打印cpu信息)、-s(打印交换分区信息)
-d:打印磁盘信息,需要指点磁盘设备名
-n:打印网络信息,接收和发送大小,需要指点网卡设备名
查看DISK(-d)和NET(-n)需要带具体的设备名(具体可以查看/proc/diskstats和/proc/net/dev中的设备或者可以取自iostat
和sar -n DEV)
Linux指标的数据都来自/proc目录下的相关系统元数据:
LOAD : /proc/loadavg
CPU : /proc/stat
SWAP : /proc/vmstat
DISK : /proc/diskstats
NET : /proc/net/dev
查看MySQL响应时间(rt)
通过调用tcprstat来监控MySQL的响应时间。
