先安裝orzdba，連結：http://blog.itpub.net/28939273/viewspace-1875895/

安裝依賴的包：
[root@hank-yoon servers]# yum install perl-TermReadKey.x86_64

否則報錯如下：
[root@hank-yoon servers]# ./orztop -u=root -p='yoon' -S=/export/data/mysql/tmp/mysql.sock

資訊中還包括了資料庫的每秒的insert/update/delete/select，邏輯讀，命中率，當前活動執行緒等，可以大致看到資料庫的當前壓力情況；
當你的例項出現效能瓶頸時，不妨用該工具看看，抓取一下當前正在跑的慢sql
