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
