The VCM Agent is not installed directly on the ESX/vSphere Servers and vCenter Servers; instead

collections are accomplished using what is referred to as "agentless collections". There are two types of

agentless collections, and each type is specific to a particular configuration. One type uses an Agent Proxy,

and the other type uses a direct call to the vSphere API using vSphere PowerCLI.

The collected data is displayed in the Console | Virtual Environments.

ESX 2.5/3.x,vSphere 4, and ESXi Servers Collections

When collecting from ESX 2.5/3.x, vSphere 4, and ESXi Servers, you must configure at least one VCM

Agent Proxy machine. The Collector communicates with the Agent Proxy, and the Agent Proxy then

directly communicates with the ESX 2.5/3.x, vSphere 4, and ESXi Servers using SSH and/or Web Services

for necessary data collection actions. In the case of ESX 2.5, the Agent Proxy communicates with the

VirtualCenter Servers to collect certain ESX 2.5 data it cannot collect directly. The data is processed by the

Agent Proxy and relayed to the Collector.

The Agent Proxy machine must be a Windows server that meets the minimum hardware and software

requirements specified in the VCM Hardware and Software Requirements Guide. A single Agent Proxy

machine supports up to 50 ESX/ESXi/vSphere Servers.

VCM Support of ESXi

VCM supports collecting Guests and Hosts data from ESXi machines. ESXi does not support SSH, and

therefore UNIX/Linux data classes data cannot be collected. Only Web Service Settings are required for

ESXi machines.

IMPORTANT When collecting from ESXi, attempting to collect any data other than VM Hosts or VM

Guests data from the ESXi machine will result in a collection failure. This includes collection filters supplied

with the product and targeted for ESX 2.5 and ESX 3.x/vSphere 4. Running such collections on all the All

VM Hosts Machine will also fail for ESXi machines.

Only the VM Hosts and VM Guests data types are available for collection, and it is not possible to run

UNIX Remote Commands. You may see SSH settings in the License VM Host wizard for the ESXi

machine, but you do not need to configure them.

vCenter Server Collections

When collecting from vCenter Server, you must configure the Collector with the necessary components,

including an Agent (installed by default), Remote Commands (VCM functionality that includes vCenter

Collection PowerShell templates to be the model for your local scripts), PowerShell 2.0, and vSphere

PowerCLI 2.0. The Collector Agent runs the vCenter Collection remote commands, which include your

Powershell scripts, and then vSphere PowerCLI accesses the vSphere APIon the vCenter Servers to

perform the necessary data collection actions. The data is relayed to the Collector and added to the

database.

When collecting using the vCenter collection remote command, neither SSH nor Web Services should be

configured when using this collection method. For configuration information, see "Configuring vCenter

Server Data Collections" on page 137.

Configuring Agent Proxy Virtualization Collections

The following table provides a list of installation and configuration procedures to follow when configuring

VCM.

IMPORTANT The steps must be executed in the order presented.
