I have been reading the following doc

http://communities.vmware.com/docs/DOC-9279

and apparently the following definitions apply

PCPU UTIL:  thread utilization
CORE UTIL:  core utilization (not the sum of the threads)

Using v5, and the esxtop example below

PCPU USED(%): 0.8 0.6 0.2 0.2 0.1 0.3 0.0 0.0 AVG: 0.3
PCPU UTIL(%): 1.7 1.0 0.5 0.4 0.3 0.7 0.1 0.1 AVG: 0.6
CORE UTIL(%): 2.7     0.9     1.1     0.2     AVG: 1.2

Open in new window


In core 1, the util is 2.7.   What does 2.7 mean.  Does that mean 270 percent ????? (apparently not)

What does CORE UTIL tell me about core 1, core 2, etc

Thanks
