Which three metrics are checked to diagnose a memory bottleneck at the ESXi host level? (Choose three)

A.
MEMSZ

B.
MEMCTL

C.

D.

E.
MCTLTGT

Explanation:
THIS IS A HIGHLY DEBATED QUESTION – SOOoooo If you think it is wrong please research thoroughly before requesting an update… an official response from VMware would be nice. 😀

3 metrics to diagnose a memory bottleneck at the ESXi host level: MEMSZ, MEMCTL, SWAP.

MEMSZ – Amount of physical memory allocated to a resource pool or virtual machine.
MEMCTL – Displays the memory balloon statistics. All numbers are in megabytes.
MCILTGT – Amount of physical memory the ESXi system attempts to reclaim from the resource pool or virtual machine by way of ballooning.
SWAP – When the VMkernel on the host is swapping memory to disk

Revised; Answer is MEMSZ,MEMCTL,SWAP. Checked with VMWARE on this. Renegade_ZA
