Install standalone and additional components

You can install standalone components that provide advanced features for working with your performance tests.

Note: For all standalone applications, you must first manually install the prerequisite applications. For details, see the Support Matrix.

Install standalone components on Windows

The following standalone components are available for install on Windows.

Component	Description
OneLG	Instead of installing a host and then configuring it as a load generator, you can install a standalone version of the load generator (OneLG). This host can behave only as a load generator, unlike the host, which can also be configured as a Controller or data processor. You can use a local or a cloud-based machine to host your load generator. Note: If you know in advance that a host machine is to be used as a load generator only, we recommend that you install OneLG for the following reasons: The installation requires less disk space Moving the load generator's setup files is less time consuming than moving the setup files of the host.
OpenText Virtual User Generator	OpenText Virtual User Generator (VuGen) generates virtual users, or Vusers, by recording actions that typical end-users would perform on your application. VuGen records your actions into automated Vuser scripts which form the foundation of your performance tests.
Analysis	Analysis provides graphs and reports with in-depth performance analysis information. Using these graphs and reports, you can pinpoint and identify the bottlenecks in your application and determine what changes need to be made to your system to improve its performance.
MI Listener	The MI Listener is one of the components needed to run Vusers and monitor applications over a firewall. To install, run SetupMIListener.exe. For details about firewalls, see Configuration options.
Monitor Over Firewall Agent	Used to monitor servers that are located over a firewall. For details about firewalls in OpenText Enterprise Performance Engineering, see Configuration options.

To install standalone components on Windows:

From the installation directory, run setup.exe. The setup program displays the installation menu page.
Select one of the following options: OneLG, VuGen, Analysis, MI Listener, or Monitors Over Firewall. For details, see the OpenText Professional Performance Engineering Help Center.
Note:
- During the installation of Load Generator Standalone, MI Listener, or Monitors over Firewall components, the setup wizard prompts you to select the mode for running the installed agent. Select OpenText Enterprise Performance Engineering mode.
  
  The agent runs as a service under a special account named IUSR_METRO. This is a local Windows account, created during the installation process (some additional configuration is also added on the load generator).
  
  You can delete the IUSR_METRO account only if the system user was configured to a different Windows account; otherwise the host does not function correctly.
- If you attempt to install standalone components on a system drive other than the default C drive, you get a warning that you are out of disk space on your system drive even though you are not installing there. This is because the installer, while installing the components to the drive as specified by the user, still needs to use the Windows temporary file locations during installation.
  
  Solution: Free up space on your C system drive.
(MI Listener/Monitors Over Firewall installations only) Follow the instructions in the installation wizard. After installation, the configuration wizard opens, requesting the name of the product you are working with. Select OpenText Enterprise Performance Engineering.

Silently install standalone applications on Windows

This section describes how to perform a silent installation of the standalone applications.

Note: For instructions on silently installing load generators on Linux, see the OpenText Professional Performance Engineering Help Center.

Choose one of the following options:

Option 1: Install the prerequisite software and the application separately
Option 2: Install the prerequisite software and the application together

Option 1: Install the prerequisite software and the application separately

Install required prerequisite software. For details, see Prerequisite software.
Extract the Load Generator installation files to a local directory:

Select an application from the <installdir>\Standalone Applications folder.
Extract the .msi file from the .exe application to the installation folder.

Run one of the following commands from the command line:

Load Generator:
Copy code
```
msiexec /i "<installdir>\OneLG_x64.msi" /qb /l*vx "<Path to log file>" IS_RUNAS_SERVICE=1 START_LGA="1"
```
VuGen Standalone:
Copy code
```
msiexec /i "<installdir>\VuGen_x64.msi" /qb /l*vx "<Path to log file>"
```
Analysis Standalone:
Copy code
```
msiexec /i "<installdir>\Analysis_x64.msi" /qb /l*vx "<Path to log file>"
```
where <installdir> is the local directory where you saved the installation files, and <Path to log file> is the full path to the installation log file.

Note: You can install the Load Generator component on a Linux platform to run virtual users. The Linux virtual users interact with the Controller, installed on a Windows machine. For details on installing the Load Generator on Linux, see the OpenText Professional Performance Engineering Installation Guide available from the OpenText Professional Performance Engineering Help Center.

Option 2: Install the prerequisite software and the application together

Select an application from the <installdir>\Additional Component\Applications folder.

Run one of the following commands from the command line.

Load Generator:

Copy code

SetupOneLG.exe -s -sp"/s" IS_RUNAS_SERVICE=1 START_LGA=1 NVINSTALL=Y

VuGen Standalone:

Copy code

SetupVuGen.exe /s /a /s INSTALLDIR="c:\OpenText\VuGen_SA"

Analysis Standalone:

Copy code

SetupAnalysis.exe /s /a /s

Install a load generator on Linux

You can install the load generator component on a Linux platform to run virtual users. The Linux virtual users interact with the Controller, installed on a Windows machine. For details on installing the load generator on Linux, see the OpenText Professional Performance Engineering Help Center.

Install additional components

You can install additional components that provide advanced features for working with performance tests. You install these components from the Additional Components directory, located in the root directory of the installation directory.

The following components are available.

Component	Description
Agent for Citrix Server	Installs an optional component on the server machine that enhances VuGen's capabilities in identifying Citrix client objects.
Agent for Microsoft Terminal Server.	Used for extended RDP protocol record-replay. This component runs on the server side, and is used to create and run enhanced RDP scripts.
