To prepare for the App Visibility proxy component

As the system administrator, configure your network to ensure that the App Visibility proxy can collect end-user browser data, and pass it on to the App Visibility collector and portal.

Before you install the App Visibility proxy, configure the following items:

Define a host name that resolves to the App Visibility proxy’s IP address, or to a Virtual IP on a load balancing server.
Create a certificate in which the Common Name matches the defined host name.
Configure the load balancing server to do the following:
- Negotiate HTTPS using the certificate created in Step 2.
- Redirect end-user HTTP/HTTPS requests from this host name to the host:port of the App Visibility proxy.

To configure the required Terminal Server options

On a Windows operating system, to run the installation utility through a Terminal Services connection or a remote desktop session, configure the Terminal Server options that pertain to temporary folders.

On the host computer, open the Local Group Policy Editor by selecting Start > Run and typing gpedit.msc.
Expand the following folder: Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Temporary folders.
Double-click the following options to set each to Enabled:
- Do not delete temp folder upon exit
- Do not use temporary folders per session
Restart the computer.

Troubleshooting tip

If you receive a notification about Terminal Server configuration when you run the installation, perform the following steps to back up the registry and adjust the registry key values as follows:

On the host computer, open the Registry Editor by selecting Start > Run and typing regedit.
Expand the following folder: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server.
Set the value for PerSessionTempDir and DeleteTempDirsOnExit to 0.
Restart the computer.

Note

You can revert these changes after you complete the installation process. You might need to restart the computer.
