A company runs several instances of an application that requires large amounts of memory.
Which three metrics are checked to diagnose a memory bottleneck at the ESXi host level? (Choose three)
A.
MEMSZ
B.
MEMCTL
C.
SWAP
D.
ZIP
E.
MCILTGT
Explanation:
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
A, E – wrong, does not indicate shortage of memory
B – memory baloon is higher, when vmware needs to take away memory allready allocated to VM
C – memory swap to disk is classical memory shortage
D – ZIP indicates memory is compressed, which also show memory shortage
