Innotop介绍
Innotop是一款Perl脚本编写、开源、功能强大的MySQ的监控工具，它通过文本模式（命令行模式）监控，功能强大，配置简单，易于使用等等特性。Innotop这个项目位于https://github.com/innotop/innotop上。官方的介绍如下：
innotop is a 'top' clone for MySQL with many features and flexibility.
· completely customizable; it even has a plugin interface
· monitors many servers at once and can aggregate across them
The manual is embedded into the program in Perl's POD format, so it should be available through perldoc and man, and is still available online on the previous hosting (the project moved from google code to git): http://innotop.googlecode.com/svn/html/index.html
Innotop安装
在安装之前先要确定你的系统安装了Time::HiRes,Term::ReadKey,DBI,DBD::mysql这四个包。当然在执行perl Makefile.PL命令是会检查这些依赖项，如下所示：
[root@DB-Server ~]# cd /tmp
[root@DB-Server tmp]# unzip innotop-master.zip
[root@DB-Server tmp]# cd innotop-master/
[root@DB-Serverinnotop-master]# ls
Changelog COPYING innotop innotop.spec INSTALL Makefile.PL MANIFEST README.md snapshot_queries.png t
[root@DB-Server innotop-master]# perl Makefile.PL
Checking if your kit is complete...
Looks good
