Esxtop allows monitoring and collection of data for all system resources: CPU, memory, disk and network. When used interactively, this data can be viewed on different types of screens; one each for CPU statistics, memory statistics, network statistics, disk adapter statistics,  disk device statistics, disk  VM  statistics and interrupt statistics.

= Starting ESXTOP =

<code>
esxtop
</code>

== Switching View ==
You can switch view in esxtop using these characters:

* c: cpu
* m: memory
* d: disk
* n: network

= Modifying ESXTOP =

== Extra Columns ==
Say you want to show the ZERO pages in the Memory page:

* Go to the memory page (m)
* Type f to get an overview of available columns
* Type m to select the COW columns (Now you get ZERO and a couple of other columns as well) and enter to go back to the memory overview.

== Just Virtual Machines ==
If you want to see esxtop just for Virtual machines launch it, and type V for only VMs. Type V again to view everything again.
