QUESTION 41
A company runs several instances of multi-threaded application that requires virtual machines to be configured with multiple vCPUs.
Which metric is checked to determine if CPU contention exists on
an ESXi 5.x host?
A. %RUN
B. %WAIT
C. %USED
D. %RDY
Answer: D
Explanation:
http://communities.vmware.com/docs/DOC-9279
“%WAIT”
The percentage of time the world spent in wait state.
This %WAIT is the total wait time. I.e., the world is waiting for some VMKernel resource. This wait time includes I/O wait time, idle time and among other resources. Idle time is presented as %IDLE.
“%RDY”
The percentage of time the world was ready to run.
A world in a run queue is waiting for CPU scheduler to let it run on a PCPU. %RDY accounts the percentage of this time. So, it is always smaller than 100%.
+Q: How do I know CPU resource is under contention?+
+A: %RDY is a main indicator. But, it is not sufficient by itself.+
