An in-depth look at the Citrix FMA Server VDA… The one that (almost) got away!

Average time to read: 5 minutes

Ever since the introduction of XenDesktop 7, where the FMA took over and XenApp was integrated, a lot has been written with regards to its components, services, agents and so on. What surprises me though, is that the Server VDA is (almost) never mentioned, while this is, or at least was a brand new component. Never before was it optional to install a (relatively) lightweight agent onto a XenApp server, it was basically all or nothing.

12 services that make up the Citrix XenDesktop Flex Management Architecture!

Average time to read: 6 minutes

The Flex Management Architecture is a service-orientated architecture, it consists out of ten, or twelve depending on your point of view, primary services in total. Let me explain, when administering a Virtual Desktop Infrastructure (VDI) for example, the Broker Service, a.k.a. the Desktop service, and the PortICA service both live on your desktop OS based VM’s, which are then part of the FMA as well, making it twelve services in total. Here I’ll provide you with a rundown of all services that make up the FMA including their responsibilities and some background information. I’ve included some artwork as well.

Troubleshooting the XenDesktop FMA… Citrix Scout deep dive – Part one!

Average time to read: 18 minutes

About two weeks ago I wrote (slides included) about my talk at the Dutch Citrix User Group (DuCUG) where I presented about troubleshooting the FMA. I also mentioned that when we do have to deal with CTX Support, and note that I’m not trying to sound negative here, we need to understand what to do when we are asked to inventory our Sites or to (CDF) trace certain components / modules for example. I also went into a bit more detail regarding CDF traces and the accompanying modules and trace messages that come with it, including some of the steps we can take to interpreted the collected data ourselves. That’s what I’d like to discuss in this (short) two part series as well, let’s have a closer look at Scout, CDF tracing / control, some of the FMA services (PortICA) etc… I’ll start out with some of the basics and take it from there.

XenDesktop 7.x internals continued… The Server VDA in more detail.

Average time to read: 3 minutes

Although the new FMA based Server VDA has been built from the ground up it still has a lot of similarities when compared to the ‘old’ ICA protocol stack deployed with XenApp 6.5 and earlier versions. However, unlike XenApp, the VDA (Virtual Delivery Agent) directly communicates with the Delivery Controller, it does this through the Broker Agent, basically the same way as we are used to with the desktop VDA (PortICA).

Troubleshooting Citrix XenDesktop & XenApp 7.x ? Read this !

Average time to read: 15 minutes

When I was thinking about what to write next I thought it might be a good idea to use something ‘from the field’, an issue that I’ve been involved in personally during the past two weeks or so. Then I figured, why just discuss one specific use case when there is so much more to tell. So I won’t, instead I’ll focus on troubleshooting in general and use my ‘real world’ example as a reference throughout this article.
