Virtual Machine under ESX: VMkernel swapping on the Host System
Monitor the ESX Performance counters mem.swapin, mem.swapout and mem.swapused on a ESX host system.
mem.swapin: Sum of swapin values for all powered-on virtual machines on the host.
mem.swapout: Sum of swapout metrics from all powered-on virtual machines on the host.
mem.swapused: Amount of memory that is used by swap.
One service is created for the VMKernel swap metrics on the ESX host system.
