The resxtop and esxtop command-line utilities provide a detailed look at how ESXi uses resources in real time. Also, esxtop displays information about the state of the physical server running an ESXi Server.
It lists CPU utilization for each physical processor, memory utilization, and disk and network bandwidth for each network and disk device available to the ESX Server machine. Furthermore, esxtop lists CPU and memory utilization for each individual VMkernel world.
Memory utilization is characterized by the type of memory (for example, shared, private, or swapped) that is being consumed. These CPU and memory statistics let you monitor the resource utilization for each of your virtual machines.
