其實(shí)很簡(jiǎn)單，就是利用linux下的 watch 工具來(lái)做監(jiān)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 |

參數(shù)解釋：

-d --differences
-n --interval

不用我多說了吧，怎么樣，是不是覺得很有意思呢 :)
