Each of the following lines contains the performance data for those counter instances in one snapshot. Esxtop bzlloon mode output can be loaded in perfmon directly. This happens purely due to the fact that height of the esxfop is limited in what it can display. VMKernel may use some of the managed memory. For each NUMA node there are two statistics: Adding disk spindles or changing the RAID level may help in such cases.
GRANT accounts the guest physical memory, it may not be the same as the mapped machine memory, due to page sharing. A large number of queued commands may be esxtip indication that the storage system is overloaded. Email Address Required, will not be published. This is an internal counter.
The arithmetic mean of CPU loads in 1 minute, 5 minutes, and 15 minutes, based on 6-second samples.

Touched memory is a working set estimate, which indicates how actively the VM is using its memory. This counter reports the amount of memory that the balloon driver is currently holding for use by other VMs. The stats are related, but not the same.
VMKernel then scales this number by the size of VM's configured memory and averages it with previous samples. These are just some parts of esxtop I have found useful, it goes much deeper with more commands and syntax here: For those using a Mac, esxplot uses specific libraries which are only available extop the 32Bit version of Python.
Because swap-in is synchronous, the VM needs to wait until the requested pages are read into machine memory. Because there are quite a number of instances related to disk statistics, let's list a few examples below.
Troubleshooting with ESXTOP
Here, this document provides simple descriptions without further discussion. VMKernel estimates active memory usage for a VM by sampling a random subset of the VM's memory resident in machine memory to detect the number of memory reads and writes.
Nalloon would expect to see a value of 0 zero in this column SWCUR tells you how much memory the virtual machine has in the.
If we want to add both reasons into account, just to make it more complicated, we can have something like this. See the filter section. Please note that since the CPU frequency may change often, you may go to the esxtop power screen, pressing 'p', to see how often the PCPU stays at what states, which can help guess the effective frequency.
You can either write it to the default config file esxtop4rc or write the configuration to a new file. This one defines how much time your virtual machine wanted to execute CPU cycles but could not get access to the physical CPU.
They are totally different.

Please also note that turbo mode may make the effective frequency higher than the nominal frequency. The default refresh interval can be changed by the command line option " -d ", or the interactive command 's'. If this happens, please check the queue statistics, which will be discussed next. The counter names in esxtop batch mode are different from the ones in interactive mode listed in the sections above. Effective minimum cpu allocation in case of resource contention.
Only displayed when the device is expanded with the "e" Disk World Statistics command. 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 following is a lot simpler than what I came up with, thanks William! ESXi pools resources together, such as logical processors, which can then be used independently by the CPU scheduler.
