Table C-5. Memory Data Counters (Continued)
Counter Label Description
Entity
V H R C
state Memory State Amount of free machine memory on the host. VMkernel has four
free-memory thresholds that affect the mechanisms used for
memory reclamation.
0 (High)
Free memory >= 6% of machine memory
- service console memory
1 (Soft)
Free memory >= 4% of machine memory
- service console memory
2 (Hard)
Free memory >= 2% of machine memory
- service console memory
3 (Low)
Free memory >= 1% of machine memory
- service console memory
For 0 and 1, swapping is favored over ballooning. For 2 and 3,
ballooning is favored over swapping.

swapin Memory Swap
In
Amount of memory that has been swapped in to memory from
disk.
VM
Total amount of memory data that has been
read in from the virtual machine’s swap file
to machine memory by the VMkernel. This
statistic refers to VMkernel swapping and
not to guest OS swapping.
Host
Sum of memory swapin of all powered on
VMs on the host.

• • ο ο
swapinRate Memory Swap
In Rate
Rate at which memory is swapped from disk into active memory
during the current interval. This counter applies to virtual
machines and is generally more useful than the swapin counter to
determine if the virtual machine is running slow due to swapping,
especially when looking at real-time statistics.
