What esxtop statistic should the administrator examine in order to validate that the guest OS is experiencing performance degradation?

A user has submitted a trouble ticket complaining that the email server VM has become very
sluggish. After looking at the logs, the vSphere administrator suspects the iSCSI network is
experiencing congestion.

GAVG/wr – Average guest operating system write latency per write operation in milliseconds.

%ACTV – Percentage of guest physical memory that is being referenced by the guest. This is an instantaneous value.

PATH – Storage path name. This name is only visible if the corresponding adapter is expanded. See interactive command e in Storage Adapter Panel Interactive Commands.

PKTRXMUL/s – Number of multicast packets received per second.

GAVG is the sum of KAVG(latency experimented by the host) + DADG(latency experimented in the actual device) so this will result in the comulative latency experimented by the actual guest VM.

I would go with A
