VMware vCenter AppSpeed Installation and Upgrade Guide
6 VMware, Inc.

VMware vCenter AppSpeed
Installation 1
You install AppSpeed on a VMware host machine that resides within the datacenter network and integrates
with the VMware vSphere Client. You install one or more AppSpeed probes on each host to be monitored.
This chapter includes the following topics:
n“Installation Prerequisites,” on page 7
n“Installation Workflow,” on page 9
Installation Prerequisites
Before installing AppSpeed, review the system and deployment requirements.
A variety of VMware ESX™ versions support AppSpeed.
nServer: ESX 3.5.x or 4.0.x Probes: ESX 3.0x, 3.5.x, or 4.0.x
nvSphere 4.x
System Requirements
Before you install AppSpeed, make sure that you have the necessary administrator privileges and system
requirements.
Review these system requirements before you install AppSpeed.
nYou must have admin-level access to vCenter Server for the automated installation process.
nYou must define routable IP addresses for servers and probes.
VMware recommends that you do not use DHCP because the IP address of AppSpeed Server might change
after setup is complete. However, if you do use DHCP, you do not need routable IP addresses.
nIf HTTPS sites are to be monitored, you require the SSL private keys.
nYou must have Administrator privileges on the client machine to install Adobe Flash Player 10.
nAdobe Flash Player 10 must be installed as an ActiveX Control; therefore, it must be downloaded using
Internet Explorer.
nVMware recommends that you synchronize the time on the hosts on which AppSpeed Server and the
AppSpeed probes will be installed. If the time is not synchronized, AppSpeed might lose data and
experience delays in the mapping process. To synchronize the time, set an NTP server in the Configuring
Time option for each ESX host in vCenter.
VMware, Inc. 7

Deployment Considerations
Your must have sufficient system resources to deploy AppSpeed.
When planning your AppSpeed deployment, make sure that you have these system resource requirements.
nServer
n40GB hard disk drive
n4GB RAM
n2 vCPUs
Virtual CPUs are created as part of the AppSpeed deployment. In addition, AppSpeed reserves
3000MHz.
nProbes
n5GB hard disk drive
n0.5GB RAM
n2 vCPUs
Virtual CPUs are created as part of the AppSpeed deployment. Two vCPUs require no more than the
equivalent resources of a single physical CPU.
Port Requirements
AppSpeed requires that specific ports be open on your firewall.
Table 1-1. Open Port Requirements
Server Connection Required Open Ports
