[Hyperic-hq-discuss] QUESTION: How do I get the number of hyperthreading cores?

[Andrew M. <and...@uk...>]

How do I use sigar to get the number of hyperthreading CPUs please? The machine I am using has a quad core intel xeon E5440.

sigar identifies 3 physical CPUs but says that each one has 1 socket with 4 CPUs in it, which means a total of 16 logical CPUs. Is that right? Is that the right way to tot up the number of logical CPUs?
