其实很简单，就是利用linux下的
watch 工具来做监控，方法如下：
[yejr@localhost imysql]# watch -d -n 10 "egrep 'MySQL thread|Log|Modified db pages' innodb_status.3249 " Every 10.0s: egrep 'MySQL thread|Log|Modified db pages' innodb_status.3249 Thu Apr 9 10:01:12 2009 MySQL thread id 6, query id 71 localhost root Sending data Log sequence number 2703 3443241402 Log flushed up to 2703 3442763607 Modified db pages 83325
或者：
[yejr@localhost imysql]#watch -d -n 10 "mysqladmin ext|egrep Innodb_data" Every 10.0s: mysqladmin ext|egrep Innodb_data Thu Apr 9 10:03:55 2009 | Innodb_data_fsyncs | 4144699 | | Innodb_data_pending_fsyncs | 0 | | Innodb_data_pending_reads | 0 | | Innodb_data_pending_writes | 0 | | Innodb_data_read | 5567172608 | | Innodb_data_reads | 298413 | | Innodb_data_writes | 4492881 | | Innodb_data_written | 18549422080 |
参数解释：
-d --differences -n --interval
不用我多说了吧，怎么样，是不是觉得很有意思呢 :)
