1 AppSpeed Installation Overview 1 VMware vCenter AppSpeed provides performance management and service‐level reporting for applications running within virtual appliances. AppSpeed analyzes the traffic that flows between end users, Web applications, and back‐end servers. This analysis provides visibility into multitier applications and enables rapid identification of performance issues originating from inadequate resource allocation and application problems.
VMware vCenter AppSpeed Installation Guide System Requirements Review the following system requirements before you install AppSpeed: You must have admin‐level access to vCenter Server for the automated installation process. Routable IP addresses for servers and probes need to be defined. NOTE Using DHCP is not recommended. However, if DHCP is used, you do not need routable IP addresses. If HTTPS sites are to be monitored, an SSL private key is required.
2 Installing and Configuring the AppSpeed Server 2 The first stage in the installation process is to import the OVF file and install and configure the AppSpeed server. You can install the AppSpeed server on any ESX host that is managed by the monitored vCenter.
