Below are some values that I use pretty frequently when troubleshooting a virtual workload and or VMWare ESXi kernel/host even VM issue.  ESXTOP really can be one of the best and under-utilized tools in the environment to gain insight in real time.

ESXTOP -> C (Compute)

ESXTOP -> M (Memory)

ESXTOP -> D (Disk)

ESXTOP -> U (LUN)

ESXTOP ->N (Network)
