Appendix C Performance Metrics Table C-5. Memory Data Counters (Continued) Counter usage vmmemctl Label Description Memory Usage Memory usage as percentage of total configured or available memory. VM memory usage = memory active ÷ virtual machine physical memory size Host memory usage = memory consumed ÷ host configured memory size Cluster memory usage = memory consumed + memory overhead ÷ effectivemem Memory Balloon n Stats Type: absolute n Unit: percent n Rollup Type: average (min/max) n Collection Level: 1(4) Amount of memory allocated by the virtual machine memory control driver, which is installed with VMware Tools. VM Amount of guest physical memory that is currently reclaimed from the virtual machine through ballooning. This is the amount of guest physical memory that has been allocated and pinned by the balloon driver. Host Sum of Memory Balloon of all powered on virtual machines and vSphere services on the host. If the balloon target value is greater than the balloon value, the VMkernel inflates the balloon, causing more virtual machine memory to be reclaimed. If the balloon target value is less than the balloon value, the VMkernel deflate the balloon, which allows the virtual machine to consume additional memory if needed. Virtual machines initiate memory reallocation. Therefore, it is possible to have a balloon target value of 0 and balloon value greater than 0. n Stats Type: absolute n Unit: kiloBytes n Rollup Type: average (min/max) n Collection Level: 1(4) Entity VHR C ••ο ο VMware, Inc. 343
