vSphere Basic System Administration Table C-5. Memory Data Counters (Continued) Counter Label Description Entity VHR 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 swapin Memory Swap In For 0 and 1, swapping is favored over ballooning. For 2 and 3, ballooning is favored over swapping. n Stats Type: absolute n Unit: number n Rollup Type: latest n Collection Level: 2 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 n Stats Type: absolute n Unit: kiloBytes n Rollup Type: average (min/max) n Collection Level: 1(4) 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. n Stats Type: rate n Unit: kiloBytesPerSecond n Rollup Type: average (min/max) n Collection Level: 1(4) 340 VMware, Inc.
