/proc/vmware/mem
Reading from this file reports the maximum size with which a new virtual machine
can be powered on, admission control status including the amount of unreserved
memory and unreserved swap space and the current amount of free memory in the
system.
/proc/vmware/pshare/status
Reading from this file reports various detailed statistics about the current status of
transparent page sharing.
/proc/vmware/swap/stats
Reading from this file reports various detailed swap statistics.
/proc/vmware/config/MemSharesPerMBLow
This option specifies the a numerical value for the low shares value. By default, this
number is 5.This number is multiplied by the virtual machine’s maximum memory
size to obtain the number of shares.
/proc/vmware/config/MemSharesPerMBNormal
This option specifies the a numerical value for the normal shares value. By default, this
number is 10. This number is multiplied by the virtual machine’s maximum memory
size to obtain the number of shares.
/proc/vmware/config/MemSharesPerMBHigh
This option specifies the a numerical value for the high shares value. By default, this
number is 20. This number is multiplied by the virtual machine’s maximum memory
size to obtain the number of shares.
/proc/vmware/config/MemBalancePeriod
This ESX Server option specifies the periodic time interval, in seconds, for automatic
memory reallocations. Reallocations are also triggered by significant changes in the
amount of free memory. The default is 15 seconds.
/proc/vmware/config/MemSamplePeriod
This ESX Server option specifies the periodic time interval, measured in seconds of
virtual machine virtual time, over which memory activity is monitored in order to
estimate working set sizes. The default is 30 seconds.
/proc/vmware/config/MemIdleTax
This ESX Server option specifies the idle memory tax rate as a percentage. A tax rate of
x percent means that up to x percent of a virtual machine's idle memory may be
reclaimed. Virtual machines are charged more for idle memory, than for memory that
they are actively using. A tax rate of 0 percent defines an allocation policy that ignores
working sets and allocates memory strictly based on shares. A high tax rate results in
