Is pvesh get nodes reporting incorrect cpu maxcount ?

[pschonmann]

Hi i tried to ge some info about nodes via pvesh and get probably wrong value ...

Tried this code

root@e3-1270v6s5:~# pvesh get nodes --noborder --human-readable=1

Am i wrong ? Misinterpreting values ? Or is it bug ?
Thanks for help. Have a nice day.

To me it seems the command gives back not the core count but the thread count.

Your first example has 4 cores and 8 threads.
Your second example has 10 cores and 20 threads and I assume it is a dual processor system?

That's only from a look at it. Has to be confirmed from someone with knowledge.

yes that returns the 'logical' core count (iow. threads)
