### VMware ESX kernel vmknic stats
### Displays VMkernel port statistics on VMware ESX servers
# NOTE TO USERS: command-line plugin configuration is not yet possible, so I've
# "borrowed" the -N argument.
# EXAMPLES:
# # dstat --vmknic -N vmk1
# You can even combine the Linux and VMkernel network stats (just don't just "total").
# # dstat --vmknic -n -N vmk0,vswif0
# NB Data comes from /proc/vmware/net/tcpip/ifconfig
