赢得2008年Perfmon数据显示超过400% [英] Win 2008 Perfmon data showing more than 400%
问题描述
大家好,我在4 CPU系统上安装了Windows Server 2008。当我使用Perfmon进程/< Abc> /%处理器时间监视特定进程时,我得到的数据点显示utiization超过400%。处理器/%处理器时间的对应点显示为100%。逻辑上,对于4 cpu系统,utlization不应超过400%。
谢谢你

问: 为什么我看到计数器值出现大幅突然的峰值?
这可能是由计数器值中的整数溢出引起的,导致从较小的值中减去较大的值。 跨度>
Hi all,
I am having a Windows server 2008 installed on a 4 CPU system. When I am monitoring a particular process using Perfmon process/<Abc>/%processor time I am getting the data points which shows the utiization more than 400% . The corresponding points for processor/%Processor Time shows 100%. Logically the utlization should not cross more than 400% for a 4 cpu system.
Thanks
AJ
From the FAQ:
Q: Why do I see a large, sudden spike in the value for a counter?
This may be caused by an integer overflow in the counter value, resulting in a larger value being subtracted from a smaller one.
