Marco has been rewarded with the vExpert status from – A VM’s guest physical memory could be mapped to machine memory, reclaimed by balloon driver, or swapped to disk, or never touched.

Please refer to “Resource Management Guide” for details. If you have a driver that is esxto PAE-aware, then this counter is updated if accesses to this memory region result in copies by the vmkernel into a lower memory location before issuing the request to the adapter.

Follow me on Twitter! All values are averages over the measurement interval. See above for the internal use of this counter. The LOAD counter values is the ratio of this value with respect to the queue depth.

CPU, memory, disk and network. If this VM is swapping out memory due to resource contention, it usually means VMKernel does extop have enough machine memory to meet memory demands from all the VMs. Each queue has an associated latency, dictated by its size and whether the IO load is low or high, which affects the throughput and latency seen by applications inside VMs. The possible side effects are a reducing the memory cache used by guest OS, b guest swapping.

Again, note that it is the VMKernel swapping not the guest swapping. Note that the actual swapping is done at the group level.

In the batch mode, data can be redirected to a file for offline uses. If not, the time spent i. If the effective frequency is 1. Please note that the above inequations may not hold due to frequency scaling, which is discussed next.

Inside each VM, the guest OS maps the virtual memory to its physical memory. Yes, it is very bad.

The group stats is the sum of the worlds. This site uses Akismet to reduce spam.

The ESX storage stack allows these virtual disks to be located on any of the multiple storage options available. It eextop possible to drill down to expanded views of this data.


It is the list of devices separated by comma’s. Many esxtop statistics are computed as rates, e.

The ATS operation atomically compares an on-disk sector to a given buffer, statisticx, if the two are identical, writes new esztop into the on-disk sector. Due to ESX Page Sharing technology, guest physical pages with the same content can be mapped to the same machine page…”.

In the batch mode, data can be redirected to a file for offline uses. All virtual disks in virtual machines are seen as virtual SCSI disks. Interpreting VMware esxtop 4. It can indicate that the storage system is unable to meet the demands of the guest operating system.

Rate at which memory is being swapped in from disk. For a VM, it is the current amount of guest physical memory swapped out to the backing store.
