You can monitor the performance of a machine in your environment during Load and Performance testing or End-to-End monitoring. This will give you diagnostic information and insight into how your environment is performing in correlation to application performance/user experience.
This article will outline the setup of LoadGen Cloud - Systems Under Test. For the on-premises Systems Under Test information, please read this article.
Systems Under Test menu overview
Within the Systems Under Test menu you can find three options:
- Profiles: the SUT profile brings everything together. Connect SUT Machines (from these machines the Performance Counters are collected), with SUT Templates (templates make it possible to create a set of Performance Counters), and LoadGen Agents. The LoadGen Agents can be placed strategically, from the LoadGen Agent a direct connection is made to the SUT Machine. During a LoadGen End-to-End Monitoring - active / running - session the Performance Counters will be collected from the SUT Machines.
- Templates: with SUT Templates you can create a set of Performance Counters, so you can easily retrieve Performance Counters for a specific goal. As an example, you can create a default template that will retrieve processor, memory, and disk counters. Read more about SUT Templates in this article.
- Machines: The SUT Machines are the actual machine which we collect the Performance Counters from. Read more about SUT Machines in this article.
Profiles
In this menu option, you can easily create your Sytems Under Test Profile. With several steps, we lead you to the process to set up your LoadGen Systems Under Test setup.
Step 1: Name
The first step is to name your SUT Profile.
Step 2: Agents
Date and times will be sent from the LoadGen Agents in UTC format
All of the dates and times which are retrieved from the LoadGen Agents are stored in UTC date and time format. To convert this to your time zone you can use the AddHours( [ActualTime], +n or -n) function. Read more about working with this data in this article.
LoadGen Agents are used to launch the actual session to the Target Environment (Citrix, Azure Virtual Desktop, Microsoft Remote Desktop, VMware Horizon, or Windows 7, Windows 10, or Windows 11 FAT client) and/or collect Performance Counters from the System Under Test machines. The LoadGen Agent can be installed anywhere you like (on-premises, public or private cloud) but of course, will need a connection to your own infrastructure. The LoadGen Agents only need a TCP 443 connection outbound. All the sensitive user information is stored in a Microsoft Azure Key Vault which is set up per tenant, LoadGen Agents are directly requesting sensitive information from the Key Vault and are not sent via the LoadGen Cloud.
The first time you run this wizard you must perform a couple of steps:
- Create the new LoadGen Agent: the LoadGen Agent will create a connection to each SUT Machine and collect the Performance Counters based on the SUT template. Read more about creating a LoadGen Agent in this article.
- Create a Run as Profile: the Run as Profile is the local administrator account that can perform Operating System actions such as logon, logoff, lock, unlock and restart the machine. Read more about Run as Profiles in this article.
- Install the LoadGen Agent service: after you have set up the LoadGen Agent in the wizard, you can click the download icon. This will download the LoadGen installer executable, with a couple of steps you have the LoadGen Agent service up and running and the status of the LoadGen Agent will be set to Online.

Step 3: Connect SUT Machines to a LoadGen Agent and a SUT Template
In this step, you connect your SUT Machine to a LoadGen Agent and the SUT Template. If you don't have any SUT Machines you can create one by pressing the Create new SUT Machine button, read more about creating a SUT Machine in this article.
LoadGen Agent
The LoadGen Agent will create a connection to each SUT Machine and collect the Performance Counters based on the SUT template. Read more about creating a LoadGen Agent in this article. Only active/online LoadGen Agents will be displayed here.
SUT Template
Templates: with SUT Templates you can create a set of Performance Counters, so you can easily retrieve Performance Counters for a specific goal. As an example, you can create a default template that will retrieve processor, memory, and disk counters. Read more about SUT Templates in this article.
Step 4: Summary
The last step is the summary of your newly created Systems Under Test profile.
