statspack看CUP使用率的问题

Question

Top 5 Timed Events
~~~~~~~~~~~~~~~~~~                                                     % Total
Event                                               Waits    Time (s) Ela Time
-------------------------------------------- ------------ ----------- --------
CPU time                                                           18    73.94
log file sync                                         138           4    14.95
log file parallel write                               441           1     3.43
control file sequential read                           54           1     2.65
db file parallel write                                 32           0     2.04
          -------------------------------------------------------------
Wait Events for DB: DEV  Instance: dev  Snaps: 49 -50
-> s  - second
-> cs - centisecond -     100th of a second
-> ms - millisecond -    1000th of a second
-> us - microsecond - 1000000th of a second
-> ordered by wait time desc, waits desc (idle events last)CPU使用率高不高是看这一栏的值吗？Total Time的值高就是高？

Answer 1

Top 5 Timed Events这里能看出用了多长时间.. 不能判断cpu使用率高不高..监控cpu直接用top命令看下.. window直接看任务管理器了..

Answer 2

谢谢，我也觉得奇怪，任务管理器最多也就30%，怎么报告里显示个73%。还有就是top命令有哪些？能举两个例子并说明下是用来查看什么的吗？

Answer 3

top 是linux 的命令 。
windows之间看任务管理器就可以了linux下看CPU，敲入top就能看到了..

Answer 5

谢谢除了看任务管理器之外还有哪里什么方法看CPU的使用率吗（在statspack报告里）？关键是任务管理器里CPU使用率也是不稳定的，有没有可以量化的工具？给个具体的值什么的
