No. of processors (Physical & Virtual) ?

Hi Clint,

I have a question about the number of processors (physical & virtual) variable question. Basically I'm not sure if I am answering it correctly.

For example:

Server with 2 x quadcore CPU's (8 cores), This machine then runs several virtual machines, such as exchange with ONE CPU for instance. After capturing the log file for this exchange server & running PAL, I have only been entering one CPU to answer the question. Is this correct?

Great tool by the way! I appreciate all the time & effort that must have gone into it & your choice to go open source. :)

Correct. You want to answer with the number of CPUs that the computer has when you look at it in Task Manager.
Thanks for the feedback. :-)

Just for further clarification, are the following examples correct interpretations of this?

 

A) Physical Single Intel Core2 Duo (shows in Task Manager as 2 CPU graphs) should be 2 CPUs.

B) VM running as Single Dual Core AMD Opteron (but shows up in Task Manager as only single CPU even with view "One Graph Per CPU") should be 1 CPU.

 

I'm interpreting this as "use the number of GRAPHS shown in Task Manager" (when using one graph per CPU). Is that correct?

Yes, that is correct. The number of processors variable is used in the Context Switches/sec threshold which is based on how many logical processors that the operating system has.
