VMware vCenter AppSpeed Inst allation
AppSpeed Installation Overview
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. The analysis
enables rapid identification of performance problems that originate from inadequate resource allocation and
application problems.
AppSpeed is installed on a VMware host machine that resides within the data center network and integrates
with the VMware vSphere™ Client. AppSpeed is installed on a centralized server, with one or more AppSpeed
probes installed on each host to be monitored.
This chapter includes the following topics:

VMware vCenter AppSpeed Installation and Upgrade Guide
Installation Prerequisites
The following VMware ESX™ and vCenter versions support AppSpeed:
ESX, version 3.0.x, 3.5.x, or 4.0x
vCenter Server, version 2.5x, or vSphere 4.0
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.
You 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.
If HTTPS sites are to be monitored, you require the SSL private keys.
You must have Administrator privileges on the Client machine to install Adobe Flash Player 10.
VMware 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. You can synchronize the time by setting an NTP server in the
Configuring Time option for each ESX host in vCenter.
Deployment Considerations
When you plan your AppSpeed deployment, consider the following system resource requirements:
Server
30GB HDD
4GB RAM
2 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.
Probes
5GB HDD
0.5GB RAM
2 vCPUs
Virtual CPUs are created as part of the AppSpeed deployment. Two vCPUs require no more than the
equivalent res ource s of a s ingle physical CPU. AppSpeed configures resource limits to ensur e that no
more resources than are available on the physical CPU are required at any time.
8 VMware, Inc.

monitor additional vSwitches. The probe settings, including the management network, storage device, and
monitored vSwitches, are configured as part of the probe installation process.
You can add and remove probes. See “Install an AppSpeed Probe” on page 14 and “Delete Probes from Hosts”
on page 15.
To modify the probe configuration, see the VMware vCenter AppSpeed User’s Guide.
To configure the AppSpeed probe to monitor a vNetwork distributed switch, see “Configure AppSpeed with
vNetwork Distributed Switching” on page 17
The AppSpeed probe deployment process automatically makes the following changes in the vCenter:
Creates a snapshot of the AppSpeed Server virtual machine if one does not already exist. To save disk
space, you can remove the AppSpeed Server virtual machine snapshots after the probe installation is
complete.
Creates the AppSpeed Probes folder if it does not already exist.
Creates promiscuous port groups for the selected vSwitches.
Creates a probe by creating a linked clone of AppSpeed Server. AppSpeed Server is cloned as the probe,
then the linked clone is deleted. If the linked clone cannot be created, AppSpeed creates a new virtual
machine and copies it. The virtual machine of the probe has the appropriate hardware settings, including
CPU and memory reservation.
.

You can verify the successful installation and deployment of the probes by checking the probe status in any of
the following locations:
Recent Tasks pane of the vSphere Client
Probes Management window of the AppSpeed user interface
Servers tab or Transactions tab of the Unmapped Traffic page
If the probe is successfully installed and deployed, the status of the probe is Running. In addition, if active traffic
is present on the part of the network that the probe is monitoring, the traffic throughput is reflected accordingly.
The traffic throughput can be 0 if there is no traffic on the monitored vSwitches or if a problem occurs with the
installation. If the problem persists and you know that traffic is present, see “Troubleshooting” on page 26.
VMware, Inc. 15
Page 16
VMware vCenter AppSpeed Installation and Upgrade Guide
View Unmapped Traffic
You can view information about the unmapped servers and transactions detected on the network. Unmapped
objects are not yet mapped to a specific server or application. The number of unmapped objects typically
decreases as AppSpeed maps the environment.
To view unmapped traffic on HTTP sites that incorporate SSL protection, you must configure the SSL keys for
each endpoint where AppSpeed detects SSL traffic. See “Manage SSL Keys” on page 16.
Procedure
1 In the Inventory tree, select Applications and Servers.
2 On the page selection bar, click Unmapped Traffic.
3 View the status information for the unmapped traffic.
Server: Name of the server (Servers tab only).
Name: Name of transaction (Transa ct ions tab only).
Endpoint: IP address and ports used by the server (Servers tab only).
Latency: Average and standard deviation (STDEV) latency rates for the server or transaction.
Hits: Average number of hits per second for the server or transaction, and the total number of hits in
the specified time frame.
Throughput: Average throughput for the server or transaction, and the total throughput in the
specified time frame.
Errors: Average rate of errors, as a percentage, for the server or transaction.
Manage SSL Keys
For AppSpeed to monitor traffic on HTTPS sites that incorporate SSL protection, you must configure the SSL
keys for each endpoint, the IP address and port pair, where AppSpeed detects SSL traffic. AppSpeed supports
the configuration and monitoring of SSL keys for HTTPS sites only
View SSL Key Information
You can view the existing SSL key configuration in the AppSpeed user interface. Viewing the key
configuration will enable you to decide for which endpoints you want to provide an SSL key.
Procedure
1Click the Administration tab, and in the Management Tools pane click SSL Management.
2 View the secure site endpoints for which AppSpeed cannot monitor traffic without a key.
The Pending SSL Endpoints table lists the endpoints for which valid SSL keys are required, including
their IP addresses and ports. AppSpeed automatically identifies the SSL endpoints for which keys do
not exist.
The Monitored SSL Endpoints table lists the endpoints for which valid keys exist in AppSpeed,
including the respective server name, where available, and IP address and ports. AppSpeed monitors
traffic on these endpoints.
16 VMware, Inc.
Page 17
VMware vCenter AppSpeed Installatio n
Add an SSL Key
You can assign a key to a pending endpoint to enable AppSpeed to actively monitor its traffic.
If necessary, you can extract the SSL files from the Web server to obtain the key (see “Extracting SSL Files” on
page 23).
Procedure
1 In the SSL Management window, select the check boxes for the endpoints in the SSL Pending Endpoints
table and click Add/Update SSL key.
2 Browse to and open the key file.
The key is assigned to the selected endpoints. The endpoint moves from the SSL Pending Endpoints table
to the Monitored Endpoints table.
Configure AppSpeed with vNetwork Distributed Switching
When you install a probe in AppSpeed the distributed switches do not appear in the Probe Installation
window. You must manually configure AppSpeed to monitor these switches. AppSpeed can monitor one
vNetwork Distributed Switch in each distributed virtual port group.
You need to review the following issues before proceeding:
You must have an existing vSwitch that is not already being monitored by an AppSpeed probe. If you do
not have an available vSwitch, you must create a temporary one, as described in “Creating and Deploying
Temporary vSwitches” on page 21.
Consider whether the management network needs to be connected to the distributed vSwitch, or only to
the monitoring functionality
Consider whether the probe needs to be deployed on a distributed vSwitch or on a Cisco Nexus 1000v
switch.
Use the information in Table 2 to determine which procedures you need to perform.

Configure AppSpeed to Monitor a vNet work Distributed Switch
This section describes the basic procedures for configuring an AppSpeed probe to monitor a vNetwork
distributed switch in which the creation of a temporary vSwitch is not required.
AppSpeed can monitor vNetwork distributed switches. However, AppSpeed does not directly install a probe
to monitor such a switch.
As part of the probe installation, you need to specify an available vSwitch to monitor during the installation
process, until the probe is eventually configured to monitor the distributed vSwitch. You also need to create a
promiscuous distributed virtual port group, and change the network settings of the probe to monitor the
vNetwork distributed switch. As with vSwitches, AppSpeed monitors only the virtual machines on hosts on
which the probes are installed.
To deploy a probe, at least one vSwitch must be available on the host for the probe to monitor. If the host does
not have any vSwitches configured, or if all other vSwitches are already being monitored by other probes, you

example when no legacy switches are available for the AppSpeed probe to monitor. After a probe has been
deployed, VMware recommends that you delete the temporary switch.
Create a Temporary vSwitch
To deploy a probe, at least one vSwitch must be available on the host for the probe to monitor. If the host does
not have any vSwitches configured, or if all other vSwitches are already being monitored by other probes, you
must create a new temporary vSwitch before you deploy the new probe. If an available vSwitch exists on the
host, you do not need to create a temporary switch.
Procedure
1 In the vSphere Client, select Home. On the Inventory tab, select Hosts and Clusters.
2 Select the destination host on which to install the probe.
3 Select Configuration > Networking, and in the Virtual Switch view, select Add Networking Wizard.
4 In the Connection Type window, select the Virtual Machine option and click Next.

If you select Static IP, you must type values for each of the IP, Network, and Gateway (optional)
fields.
7Click Install Probes.
8 Review the installation summary and click OK.
N
OTE If your management network was set to a temporary vSwitch and the probe failed to communicate
with AppSpeed Server, an error message appears when the probe deployment completes. The issue is
resolved when you perform the following steps, however the error message might continue to appear as
failed in the user interface.
a Right-click the probe name, select Edit Settings and specify the management network and monitor
network settings as required. For further information, see step 3 in “Configure the AppSpeed Probe

Multiple AppSpeed Servers
You can centrally manage AppSpeed through a single user interface when more than one AppSpeed Server is
installed.
Select a Server and Switch Between Servers
When you activate AppSpeed from the vSphere client with more than one AppSpeed Server installed, you are
redirected to a selection screen where you can select which server to connect to.
Procedure
1Click the Switch Server link at the top right of the page.
2 In the selection screen, type the namespace of the server to which you want to switch.
Limitations when You Use Multiple Servers
The following limitations apply when using multiple servers.
No central license management exists.
You can apply the license key to multiple AppSpeed Servers, as long as the actual number of
monitored CPUs does not exceed the number of CPUs defined in your license.
The same virtual machine might be monitored by two or more different AppSpeed Servers. As a
result, the licenses are counted twice, once on each server. Nevertheless, only the actual number of
CPUs that are being monitored are relevant to your AppSpeed license.
Topology and monitoring information is not shared between the servers. The same application can be
mapped in two or more servers. The monitoring data in the two servers might be different because the
two servers might detect different traffic. Changes in the configuration of the application, such as names
and thresholds, in one server are not reflected in the other.
One AppSpeed Server can map the management traffic of a different AppSpeed Server as an application.
22 VMware, Inc.
Page 23
When you use the vSphere Client, you cannot connect to AppSpeed Servers that are located on different
vCenter Servers in a linked vCenter Server environment. You must use the vSphere Client to log in to each
vCenter Server on which AppSpeed Servers are located.
Extracting SSL Files
You can extract the SSL files from the Web server to obtain the SSL keys. The extraction procedure varies
according to the type of Web server. Following the extraction, you can upload the key file to AppSpeed Server,
as described in “Add an SSL Key” on page 17.
Extract SSL Files from an Apache Server

Upgrading AppSpeed
If a new version of AppSpeed is available, you can upgrade to that version.
Overview of the Upgrade Process
The AppSpeed upgrade process uses an ISO image and is fully automated. VMware provides the ISO image.
You upgrade AppSpeed by connecting the ISO image with the new version to the AppSpeed Server virtual
machine and running a command-line interface (CLI) command. The CLI command performs the following
actions:
1 Upgrades AppSpeed Server and performs two sequential reboots.
2 Sets up AppSpeed Server with the new version, keeping all configurations and monitoring data of the
previous version.
3 Creates a recovery virtual machine snapshot of the AppSpeed Server virtual machine, to which you can
revert at any time.
4 Creates a backup copy of all of the configuration and monitoring data to enable the upgrade to restore
existing data.
5 Distributes the upgraded version to all probes.
You can observe the progress of the AppSpeed Server upgrade and setup processes from the console. You can
observe the redeployment of the probes in the AppSpeed user interface.
Upgrade AppSpeed
You upgrade AppSpeed version using the ISO image that VMware provides. The upgrade process reboots
AppSpeed Server and recreates all AppSpeed probes. This might take some time.
Procedure
1 Save the ISO file to a location on your local disk.
2 In the vSphere Client, connect AppSpeed Server to the ISO file.
a Select the AppSpeed Server virtual machine in the inventory tree.
bClick the Connect CD/DVD devices icon and select Connect to ISO image on local disk from the
menu.
c Browse to the location of the ISO file.
3 Log in to the AppSpeed Server console as the console user.
4 From the default console shell, run the command upgrade_AppSpeed.
5 Press Enter to run the upgrade script.
After AppSpeed Server boots from the ISO image, it continues the upgrade process, including rebooting
and recreating the probes. This process can take up to one hour.
A message appears when the AppSpeed Server upgrade is complete.
6 When prompted, disconnect the ISO file in the Client.
The probes are recreated in the new version. You can monitor the redeployment process from the
AppSpeed Probes Deployment window.
After the upgrade is complete, verify the redeployment of the probes, as described in “Verify the Installation”
on page 15.
