Testing Citrix Published Applications is easy with Login VSI!

Hey there Login VSI fans. We are excited to release a new feature in Login VSI 4.1.7 for testing Citrix Published Applications with XenApp. We’ve been able to support Citrix XenApp for some time with some help from our professional services team, but now our default workloads are supported as hosted applications without the need for a published desktop or virtual desktop infrastructure (VDI) as the target. Of course we still provide support for any of your business critical applications you’d like to add to the workloads, and this new release makes that even easier.

Stop Wasting Time: How Time Settings Affect VDI Performance Tests

Stop Wasting Time: How Time Settings Affect VDI Performance Tests

Time zones are settings that are configured once by system administrators and are never looked at again. Why would you even bother to take a look at it again when everything works? That’s a very good question, but based on our own experience with customers, we know that the time settings are not always configured correctly. Not only can this affect your entire virtualized desktop environment, especially security authentication suffers from it, but it can also ruin your Login VSI test results. To avoid wasting your time, we will discuss time settings in this blog.

Three Lesser Known Tips for Your VDI Performance Tests (Login VSI Tips & Tricks)

Three Lesser Known Tips for Your VDI Performance Tests (Login VSI Tips & Tricks)

Two weeks ago I received an email from a customer asking if the colors in Login VSI graphs could be changed after analyzing a test. The customer mentioned that the colors don’t have enough contrast which makes it difficult to clearly distinguish the lines in the graphs. After asking our development team to implement this valuable customer feedback, it was immediately apparent that this functionality was actually already available in the Analyzer! That’s a quick way to deliver new functionality to our customers.

Citrix StoreFront Connection Issue – Trusted Domains Only

Citrix StoreFront Connection Issue – Trusted Domains Only

At Login VSI Support, we sometimes see tickets where customers are having trouble connecting the Login VSI Launcher to Citrix StoreFront. My colleague Jeffrey Hsieh already wrote a helpful blog about the most common Citrix StoreFront errors and how to avoid them during a Login VSI test.

Often I notice Login VSI customers are experiencing the “getting authentication token for resources” error because of the “trusted domains” setting. In this blog I will describe why this error occurs and how to quickly resolve it.

Customize VDI workloads the easy way: Introducing Login VSI Workload Editor Beta

Customize VDI workloads the easy way: Introducing Login VSI Workload Editor Beta

Setting up centralized virtualized desktop environments is challenging, to say the least. With so many components to configure for resiliency and optimum performance, it is hard to know when you’ve set up everything just right. Login VSI’s virtual users provide insight into VDI complexity. Virtual users will try the system out, at scale, and help identify where the environment can be improved. But sometimes the workloads of virtual users need further customization from what we provide out of the box, so to speak. Today, we’ve made a big step to make this customization easier for our customers.

Quickly parse and filter external performance data with PPD - Login VSI Tips and Tricks

Quickly parse and filter external performance data with PPD - Login VSI Tips and Tricks

If you ask the Login VSI support department what they think is the most important part of a Login VSI test they will probably reply with “performance data”. External performance data from VMware ESXtop or Microsoft Performance Monitor is extremely valuable to fully understand the impact of a Login VSI test in a centralized desktop environment. But when it comes to parsing or filtering this performance data, it can be a pain in the butt because of three reasons:

Calculating Maximum Virtual Desktop Capacity – VSImax Explained

Calculating Maximum Virtual Desktop Capacity – VSImax Explained

In virtualized desktop environments, knowing how many users any given configuration can support is critical to maintaining uptime, delivering on SLAs and providing a great desktop experience for end users. Load testing and stress testing virtualized desktop environments is a key use case for Login VSI. After running a Login VSI load test, the Analyzer provides information on the maximum capacity of your virtualized desktop environment with a number--VSImax. But you may ask how this number is actually calculated. This is an excellent question because understanding what goes into a VSImax can help you to better interpret the test results in the Login VSI Analyzer.

Scalability testing with Login VSI: X-IO perspectives

Scalability testing with Login VSI: X-IO perspectives

Guest blog by Hollis Beal, Technical Marketing at X-IO

As part of Technical Marketing at X-IO, one of the parts of my job that I enjoy the most is doing performance testing, and I was asked to share how we use Login VSI in our labs. One of the ways that we leverage Login VSI is in scalability testing for VMware Horizon View 6 with our Intelligent Storage Element (ISE) storage arrays. The main challenge that we have is we are constantly running out of CPU and RAM in the servers as we scale up the user loads when testing a single ISE system. Our testing usually consists of multiple clusters of servers, with each running different numbers of desktops, to run as many desktops as we can.

Workload Mashup - Simulate different behaviors of various users during a VDI performance test

Simulate different behaviors of various users during a VDI performance test with Workload Mashup

“How can you govern a country which has 246 varieties of cheese?”
― Charles de Gaulle

Everyone is unique and not everybody is using their desktop the same way as you do. As an IT engineer I have multiple screens open with several applications such as our support tool, an RDP client, Outlook and my browser. My sales colleagues are continuously talking on the phone and are not always interacting with their computer, and when they do, it’s usually just Outlook and our CRM. The marketing team, if—and that’s a big IF--they are working at all*, is also using different applications than I do, for example Adobe Creative Suite, a marketing automation tool and our CRM.
