LoadGen Release Q3 2021 introduces Systems Under Test collecting via LoadGen Agents
With the LoadGen Q3 2021 release we introduce a new way of collecting Systems Under Test, you can also deploy LoadGen Agents to as a hub to collect other machines' Performance Counters.
LoadGen Agent Performance
Please note that using the LoadGen Agent for launching sessions (Citrix, Microsoft Remote Desktop, VMware Horizon, and Azure Virtual Desktop) in combination with collecting Performance Counters may have a performance impact on your LoadGen Agent and thus your test results. Keep in mind that your test infrastructure can not be the bottleneck while performing a load test.
- LoadGen Agents can be used in four ways:
- to launch user sessions
- to collect performance counters.
- to use within a VDI to play workloads, VMware Horizon, and Azure Virtual Desktop.
- either a and b.
- The SUT is a totally separate process from launching the test users, test users usually don’t have enough rights to collect performance counters.
- It’s possible to have multiple Run as Profiles for either:
- LoadGen Agents, for example, you can host the LoadGen Agent on a NOT-domain joined machine, hence the separate Run As Profile.
- SUT machines are normally connected to the domain, hence the AD account with local admin rights for the machines to collect performance counters from.
- You can collect performance counters in two ways:
- From the Director – don’t install the Agent on the local machine because the Director itself will handle the process of collecting performance counters.
- From a LoadGen Agent, this is now used as stepping stones to the actual machines which you want to collect performance counters from.
Load Profile / Canvas
Add a new Systems Under Test profile
Manage Systems Under Test
- SUT Profiles: here you can create, remove and clone different SUT profiles, these profiles can be used in all of your canvasses
- Available machines: here you can create, edit and delete multiple machines. You can only use Windows machines at this time, please note that you must allow traffic to the remote machine and have a local administrator account. Read more in this article.
- Templates: templates are really convenient if you want to create specific collections of counters which you want to reuse fast
- Machines in SUT Profile: here you will link all the items together, drag and drop an available machine to this pane and link a template and/or add multiple counters at once
Step 1: Select and Configure your LoadGen Agents
Step 2: Configure Systems Under Test machines
Step 3: Add Systems Under Test machines
Step 4: Activate Systems Under Test machines
Adding a new Template
- Press the Add button.
- Add the Performance Counters via:
- An Excel file.
- Manually entering the Performance Counters.
- Retrieve the Performance Counters from a machine (which will only work through the Manage Systems Under Test wizard).
- When you retrieve the Performance Counters from a machine you can choose which machine to use.
- Choose the Performance Counters to use in your Template.
- Enter a name and description for your new Template and press Save.
