Chapter 1: General Overview The CA Nimsoft xendesktop probe monitors the health, utilization, and performance of Citrix XenDesktop-based Virtual Desktop Infrastructure (VDI) environments. The xendesktop probe performs comprehensive monitoring and data collection for various aspects of the Citrix XenDesktop VDI, providing Quality of Service (QoS) data and issuing alarms when it detects sub-optimal performance in the XenDesktop-based VDI. The probe automatically discovers virtual XenDesktops, as well as hypervisor virtual machines that power the virtual desktops that may be using VMware vsphere, Xenserver or hyper-v virtualization technologies. The probe communicates with the XenDesktop VDI environment via PowerShell commands and extracts key information for real-time monitoring. You can define alarms to be raised and propagated as CA Nimsoft alarms when specified thresholds are breached. Features Auto-discovery of the entire Citrix XenDesktop VDI environment Monitoring of clustered Citrix XenDesktop VDI environments Hierarchical display of XenDesktop desktop catalogs, groups, hypervisors, machines, user sessions, controllers, and license server Auto configuration and monitoring templates Predefined templates with selected QoS monitoring metrics and alarm thresholds Chapter 1: General Overview 7
Chapter 2: Requirements This section describes the requirements for the xendesktop probe. This section contains the following topics: Prerequisites (see page 9) Hardware Requirements (see page 9) Software Requirements (see page 10) Supported Platforms (see page 10) Prerequisites This section describes the prerequisites for this probe: XenDesktop version 5.6 or later environment. Windows PowerShell command line interface on the XenDesktop Delivery Controller (DDC) server. The latest version of PowerShell that comes with Windows Server 2008R2 or later is required. For information on configuring PowerShell for use with the xendesktop probe, see the xendesktop Guide. Windows Remote Management (WinRM) enabled on the DDC server. For instructions on enabling WinRM, see the xendesktop Guide. Hardware Requirements The xendesktop probe should be installed on a system with the following minimum resources: Memory: 2-4 GB of RAM CPU: 3 GHz dual-core processor, 32-bit or 64-bit Chapter 2: Requirements 9
Software Requirements Software Requirements The xendesktop probe requires the following software environment: Nimsoft Monitor Server 5.1.1 or later Nimsoft Robot 5.23 or later Java Virtual Machine 1.6 or later (typically installed with NMS 5.0 and later) Infrastructure Manager 4.02 or later Microsoft.NET Framework 3.5 on the system where the Infrastructure Manager application is running Important!: On 64-bit Linux systems, the Java jre included in the xendesktop probe package does not install successfully when you deploy the xendesktop probe on a CA Nimsoft robot. You must manually install the glibc.i686 library or compatible 32-bit libraries on 64-bit Linux systems where you deploy the xendesktop probe. Supported Platforms The xendesktop probe supports the same set of operating systems and databases as supported by the Nimsoft Server solution. Please refer to the Nimsoft Compatibility Support Matrix for the latest information on supported platforms. See also the Support Matrix for Nimsoft Probes, for additional specific information on the xendesktop probe. 10 xendesktop Release Notes
Chapter 3: Considerations This section describes important information to know about the xendesktop probe. This section contains the following topics: Installation Considerations (see page 11) General Use Considerations (see page 11) Installation Considerations Installation follows the standard probe distribution process. General Use Considerations None. Chapter 3: Considerations 11
Chapter 4: Known Issues and Workarounds This section describes known issues and possible workarounds for this probe. These issues and workarounds apply to the latest version of the probe unless otherwise noted. Deploying the Probe on a 64-bit Linux Machine Important!: On 64-bit Linux systems, the Java jre included in the xendesktop probe package does not install successfully when you deploy the xendesktop probe on a CA Nimsoft robot. You must manually install the glibc.i686 library or compatible 32-bit libraries on 64-bit Linux systems where you deploy the xendesktop probe. Auto-Discovery Time for Large XenDesktop Implementations In large Citrix XenDesktop VDI implementations, it may take some time for discovery to occur when you open the xendesktop probe configuration GUI, especially the first time you open the GUI. You may see a delay while the resource tree is populated in the navigation pane of the GUI. Increasing Probe Heap Space for Large XenDesktop Implementations If you have more than 3000 virtual desktops for a DDC server (represented as a resource in the xendesktop probe), you may need to increase the heap space for the probe. Heap space is allocated during probe startup. By default the heap space for the xendesktop probe is 256 MB. You can increase the heap space setting for the xendesktop probe in the Raw Configure window for the probe. Follow these steps: 1. Shift + right-click on the xendesktop probe in Infrastructure Manager. 2. Choose Raw Configure from the menu. The Raw Configure dialog opens. 3. Click startup in the left pane. 4. Select the options key and open it for editing. Chapter 4: Known Issues and Workarounds 13
General Use Considerations 5. Enter a value similar to the following: -Xms256m Xmx<nnnn>m where <nnnn> is heap space up to 2048 MB or greater. For example, to increase the heap space to 1024 MB, enter the following: -Xms256m Xmx1024m Ensure the machine where the CA Nimsoft robot and probe are deployed has enough RAM. 6. Click OK and Apply. 14 xendesktop Release Notes
