Proving Availability and Performance in a Citrix Environment

In my role as a Dynatrace Consultant I’ve had the opportunity to visit customers repeatedly over extended periods of time. This has allowed me to contribute to different approaches to solving problems, and to observe how well the solutions fit the unique needs of each customer. It helps if you’ve seen certain use cases before; however, there are always cases when you come across a customer whose requirements initially sound… read more

Citrix Session Reliability: Does it Cloud Your Network Insight?

In this post, I won’t discuss the merits – good or bad – of Citrix’s Session Reliability feature; that topic is best left to Citrix engineers. Instead, I’ll focus on the importance of understanding and managing the performance of the underlying network to ensure the best possible end-user experience, with an emphasis on potential connectivity issues that may – or may not – be related to the Session Reliability feature. read more

How to Roll Out Citrix XenDesktop Globally, Without a Hitch

In addition to Pieter Van Heck, Alasdair Patton (Delivery Architect for Dynatrace) and Mark Revill (Field Technical Services, Dynatrace) also contributed to the authoring of this post.  Windows XP is living on borrowed time: Microsoft officially ended extended support for it on 8 April 2014. It was inevitable, but now many companies and organisations across the world face the unenviable task of removing XP from their organisations without disrupting regular business… read more

Filling Citrix Visibility Gap with Application-Aware Network Performance Monitoring: Part 2 – End-User Experience Monitoring

Citrix XenApp or XenDesktop are a perfect fit for lowering the costs of desktop management and simplifying access to the hosted applications from any device. Last week we discussed some challenges to application performance monitoring (APM) introduced by Citrix. Apart from getting yet another component in the data center to take care of, the virtualized application delivery becomes “black boxed” from the APM perspective. It gets harder to isolate the fault domain to the network, the infrastructure, or the applications themselves. Today, we will look into monitoring end-user experience of applications delivered through Citrix. read more

Filling Citrix Visibility Gap with Application-Aware Network Performance Monitoring – Part 1: Load Balancing

There are many reasons why companies choose Citrix XenApp or XenDesktop. Citrix can lower the costs of desktop management and simplify access to hosted applications from any device. Citrix seems like an ideal solution but it introduces certain challenges to application performance monitoring (APM). With Citrix we get yet another component in the data center to take care of. In addition, the virtualized application delivery becomes “black boxed” from the APM perspective. It gets harder to isolate the fault domain to either the network, infrastructure or applications themselves. In this two-part series we will analyze how to discover and handle some performance issues which can happen in the Citrix enabled environment. We start by looking at how to monitor network performance to discover potential problems with load balancing. In the second part we will look into managing experience of Citrix users from the perspective of network monitoring. read more
