I just found this document which explains the “new” naming conventations/translation of the citrix plug-ins/agents.
As of 2010-03-25 (March 25th, 2010), EdgeSight 5.0 and 5.1 (all service packs) will stop functioning.
You will receive the following error message for payload uploads:
Archive load error: The archive ‘/edgesight/app/suser/ZRemoteLib.zpd#12!lsync.htm’ is not appropriately signed. The system cannot find the file specified.
The only resolution it to upgrade both components to 5.2: server and clients!!
EdgeSight versions 5.0 and 5.1 have a known issue where the trusted certificate will expire on March 25, 2010. EdgeSight software is digitally signed with the trusted certificate.

Outcome phase II Project VRC: latest generation virtualization technology doubles Terminal Server workload capacity
PQR and Login Consultants combine their strength in Project VRC, to benchmark workloads for Terminal Server (TS) on the latest hardware and virtualization software
De Meern/Amsterdam, 1 February 2010 – PQR and Login Consultants launch the results of phase II of the independent research project ‘Virtual Reality Check’ (VRC). Based on 150 new tests, Login and PQR present their findings on the influence of hardware and virtualization software on the performance of TS and Citrix XenApp, in a new whitepaper: ‘Project VRC: Phase II’.
The Research & Development project ‘Virtual Reality Check (VRC), the Platform Performance Index’ was started early 2009 by Login Consultants and PQR. Goal of the project is analyze the developments in the application and desktop virtualization market and to present the outcomes as objective as possible.
Initiators Jeroen van de Kamp, CTO Login Consultants, and Ruben Spruijt, Technical Officer at PQR, now present – as a result of 150 additional tests – the latest findings in the whitepaper ‘Project VRC: Phase II’. The document shows the impact of Terminal Servers on the performance of the latest hardware and hypervisors in the (virtualization) market. Spruijt comments: ‘During the second phase of the VRC project, I was surprised by the significant economies of scale, which was made possible by the new processor architecture. Without any change in the hypervisors, this lead to the a 100% increase of possible concurrent users. This is very promising for the future! Van de Kamp adds: “We see that hardware plays a significant part in the increase in scale. A little under two years ago we were careful to virtualize Terminal Servers and XenApp, but this has changed fundamentally. Project VRC’s outcomes substantiate that.
Phase I of the project did not compare hypervisors, but described their behavior in separate whitepapers. The market obviously did compare the outcomes of the different whitepapers, which is why we decided to take up the outcomes of Phase II in one single document. The hypervisors VMware vSphere 4, Citrix XenServer 5.5 and Microsoft Hyper-V2.0 have been tested on HP ProLiant DL380G6 servers equipped with Intel ’Nehalem’ Xeon 5500 processors. The Virtual Session Indexer (VSI) 2.1 made this possible. This product independent benchmark tool for Terminal Servers and Virtual Desktop Infrastructures, indexes the performance, base4d on the number of simultaneous working sessions on 1 machine (either virtual or physical; the number of operating systems is leading) . By doing so each platform is tested in an identical way.
People who have an interest in the project can, besides comparing the test results, also execute the tests by themselves. The used testing environment and methods are covered in the whitepaper. The VSI 2.1 tool is freely downloadable through the Login Consultants website
The Whitepaper ‘Project VRC: phase II’ is available for download via www.virtualrealitycheck.net.
Login Consultants today released VSI 2.1. Login VSI 2.1 is a specifically designed benchmark for SBC and VDI environments. VSI loads the system with simulated user workload, and focuses on how much users can run on the system before it saturates. VSI is platform and protocol independent, and configuration is simplified and automated where possible. As a result, VSI is a turn-key benchmark: perform tests within days instead of weeks, there is no need to create the workloads first. VSI is intended to be used by VDI/SBC engineers/admins, a degree in testing methodologies is not required. The free version is called “VSI 2.1 Express”, the advanced version is “VSI 2.1 PRO”.
Changes in VSI 2.1
Fixes in VSI 2.1
VSI can be downloaded from Login Consultants tools section of http://www.loginconsultants.com/downloads.
In the last week i installed a XenDesktop4 environment at a customer to build a infrastructure to make video conferencing and multimedia sessions possible.
First of all you need severals things:
The AD Account is very important. The Tool is creating a SPN, a Group and an additional OU with the name of the farm. The SPN is needed for the virtuell Clients, where the XPsAgent will be installed. This Agent will query the AD for the Farm Settings. Later more…
The Installation of the Delivery Controller is very easy and Citrix’s setup works very fine. It install all neccessary features/roles and software automatically. It is possible that the setup need the Windows Source to install something. It also reboot the machine and restart the setup…. this works good, but the Setup asks not what to install at all. Only some components. The WebInterface and Diagnostic Facility will be installed automatically. Later more about the Web interface and the Consoles!
After choosing the components the setup will ask you about the farm and later the Setup wants to know where the new farm will be created and asks about the licensing. The Setup will start and after several Minutes it will ask to install some printers. This message appears up to 6 times. The first and second time while the setup installes the printers and againg after applying some hotfixes.
If the installation has finished you must first start the AD Config Tool to select the OU where the farm communications will be stored. If the tool runs successfully you find the FarmOU and FarmGUID in the CDS Console under the view “read-only properties”.
After that you can install the XDsAgent on the vClient. Logon with a domain account! The setup should automatically find the Farm.
When installation has finished and the vClient has rebooted you can connect to the webinterface which is installed on the DDC.
Important Hints for the Setup and usage:
To see the Toolbar in the desktop session you must use the DesktopWeb (Directory DesktopAppliance) – WebInterface. This is a setting in that webinterface. Normal Webinterfaces (also V5.2.0) dont have this setting! Also the usb settings are not configurable with normal xenapp web interfaces.
When all settings and configurations are complete you can see in the toolbar the usb-button where you can connect the available devices.
If you want to use the Micrsoft TableCam you must first install the Microsoft Office Communicator 2007 R2 – The Device Drivers are included in that package.
Here some helpfull links from citrix KB:
Troubleshooting Virtual Desktop Agent Registration with Controllers in XenDesktop – CTX117248
What i used and what runs:
All Webcams were running with a very good performance! The Windows 7 Movie “wildlife” runs extremly good over the vDesktop!
Very impressive what XenDesktop 4 can do with such content!
Yesterday Citrix released the new XenDesktop Version 4. i post here the information from mycitrix.com With this new release there are four editions. the HP OEM Edition is not listed here!
The Citrix XenDesktop 4 Express Edition is a free download version that provides up to 10 virtual desktops. It is ideal for setting up a small environment and enables you to experience the performance and flexibility of virtual desktops. It includes the following technologies:
Citrix XenDesktop 4 VDI Edition offers a high-performance VDI solution for delivering virtual desktops with Citrix HDX™ technology.
Virtual Desktop Delivery Infrastructure
Citrix XenDesktop 4 Enterprise Edition offers an enterprise-class desktop virtualization solution with HDX™ technology and FlexCast™ delivery technology, that delivers the optimal virtual desktop to any user, anywhere.
Virtual Desktop Delivery Infrastructure
Citrix XenDesktop 4 Platinum Edition provides a comprehensive enterprise-class desktop virtualization solution with HDX™ technology, FlexCast™ delivery technology, advanced management, monitoring and security.
The download list is similar to the enterprise edition. Additionally the single sign-on component is listed here.
Additionally to all editions the workflow orchestration is displayed in the download section.
I found a very cool whitepaper how to set up a HA desktop virtualization environment with xen products including GSLB with Netscaler.
download it here.
Highly Recommended!
I troubleshooted an ES5.2 installation and found a strange bug with the function to display the logfiles from the ez_queue’s.
The default path for the logging is:
%ProgramFiles%\Citrix\System Monitoring\Server\EdgeSight\scripts\rssh\log. When you want to view this logs from the ES-Website you will get an error: cannot find ….Scripts\rssh\log\file.log
You can see that the folder Scripts was created during the installation in lowercase and will be used in uppercase. normally it should not be a problem.
So i reviewed the logs and in all logfiles the path is called Scripts
I renamed the folder and the logs are visible on the website.
really strange!
I found several examples how to copy a complete folder with c# and i want to share this script because for me it is the best and easiest solution. it is copy from the famous web-site csharp411
I’ve added some more functions to handle different scenarios, when the folder already exists or the files already exists.
In this example I’m setting ‘overwrite = true’ in the function File.Copy(file, dest, true);
public static void CopyFolder(string sourceFolder, string destFolder) { if (string.IsNullOrEmpty(sourceFolder)) { throw new ArgumentNullException("sourceFolder"); } if (string.IsNullOrEmpty(destFolder)) { throw new ArgumentNullException("destFolder"); } if (!Directory.Exists(sourceFolder)) { throw new ArgumentException("Source folder does not exist", "sourceFolder"); } try { if (!Directory.Exists(destFolder)) { Directory.CreateDirectory(destFolder); } string[] files = Directory.GetFiles(sourceFolder); foreach (string file in files) { string name = Path.GetFileName(file); string dest = Path.Combine(destFolder, name); File.Copy(file, dest, true); } string[] folders = Directory.GetDirectories(sourceFolder); foreach (string folder in folders) { string name = Path.GetFileName(folder); string dest = Path.Combine(destFolder, name); CopyFolder(folder, dest); } } catch (Exception er) { // Do something with this exception... } } |
some friends and colleagues told me to change the language to english, so here it is.
i killed my last Blog because i want to do a real new start. i tested enough the last months 
Enjoy!
