Configuration prerequisites

Configuring Process & Session Timeout

To change the Session Timeout:

To change the Process Timeout:

Configuring NetScaler https

To configure this, you need to specify the port and protocol in the FglAM configuration file:

vmparameter.0 = "-Dcom.dell.netscaler.10.30.180.70.protocol=https";

vmparameter.1 = "-Dcom.dell.netscaler.10.30.180.70.protocol.port=443";

Configuring your XenDesktop system for monitoring

To discover your XenDesktop environment for configuration, you must enable a remote connection to at least one of the XenDesktop Delivery Controllers in your XenDesktop site. Follow the instructions in Configuring a remote connection on a XenDesktop Delivery Controller to enable the remote connection for a XenDesktop Delivery Controller in each XenDesktop site.

To monitor the License Server, StoreFront Server, Database Server, Domain Controller Server, and Delivery Controllers that the XenDesktop Discovery Wizard detects in a XenDesktop environment, you must enable remote connections to the machines running these components. See Configuring remote connections on a License Server, StoreFront Server, Database Server, Domain Controller Server, and Multiple Delivery Controllers for instructions.

Monitoring process-level information for each virtual application requires that a remote connection to each virtual machine is enabled. To simplify the configuration process, it is recommended that you enable a remote connection on the XenDesktop virtual machine’s master image. For complete instructions on how to enable a remote connection on a master image and to update it, see Configuring XenDesktop Master Images for monitoring virtual applications.

XenDesktop agents rely on the Foglight Agent Manager services to collect data from the monitored system. These remote connections use Kerberos authentication. It is recommended that you verify the Kerberos configuration before creating XenDesktop agent instances. For more information, see Configuring the Agent Manager Kerberos settings.

Obtaining WinRM (or DCOM) scripts

Foglight for Citrix XenDesktop and XenApp comes with scripts that allow you to automatically configure your WinRM or DCOM connection:

While both WinRM and DCOM connections are supported, WinRM is recommended. The scripts are available for download from the Foglight browser interface. Running a WinRM or DCOM script on the XenDesktop Delivery Controller allows you to automatically configure remote connections.

To configure a remote connection using a WinRM or DCOM script:
  1. Log in to the Foglight browser interface.
  2. On the navigation panel, under Dashboards, choose Administration > Cartridges > Components for Download.
  3. On the Cartridge Inventory dashboard, locate the row containing WinRM PowerShell automation script or DCom PowerShell automation script, as required, and click to download it.
    For more information about the Cartridge Inventory dashboard, see the Administration and Configuration Help.
    Tip: The WinRM and DCOM scripts are also available for download from the XenDesktop Discovery Wizard. For more information about this wizard, see the Foglight for Citrix XenDesktop and XenApp User Guide.

Configuring a remote connection on a XenDesktop Delivery Controller

After obtaining a WinRM or DCOM script, use it to configure a remote connection on your XenDesktop Delivery Controller.

To configure a remote connection on a XenDesktop Delivery Controller:
  1. Log in to the XenDesktop Delivery Controller machine.
  2. Copy the ZIP file containing the WinRM script to the XenDesktop Delivery Controller machine, and extract its contents, consisting of a readme file and a PowerShell script.
  3. Review the instructions in the readme. Run the PowerShell script locally on the XenDesktop Delivery Controller machine.

Configuring remote connections on a License Server, StoreFront Server, Database Server, Domain Controller Server, and Multiple Delivery Controllers

After obtaining a WinRM or DCOM script, use it to configure a remote connection on your Citrix components, including the License Server, StoreFront Server, Database Server, Domain Controller Server, and multiple Delivery Controllers.

To configure remote connection on a License Server, StoreFront Server, Database Server, Domain Controller Server, and Delivery Controllers:
  1. For each License Server, StoreFront Server, Database Server, Domain Controller Server, and Delivery Controller that you want to configure, log in to its machine.
  2. Copy the ZIP file containing the WinRM script to each machine, and extract its contents, consisting of a readme file and a PowerShell script.
  3. Review the instructions in the readme. Run the PowerShell script locally on each machine.

Configuring XenDesktop Master Images for monitoring virtual applications

To collect the performance metrics from a virtual application, Foglight for Citrix XenDesktop and XenApp must connect to the virtual machines providing virtual application instances using a WinRM or DCOM connection in order to collect the virtual application process data.

Note: The configuration described in this step is optional. It is only required if you want to collect the virtual application process data.

To simplify this workflow, it is recommended to enable WinRM or DCOM connectivity on the XenDesktop machine’s master image. A master image is a template that you use to deploy your environment. Creating a master image involves installing and configuring the operating system and any software you want to include on your image.

Start by obtaining the WinRM or DCOM script. The scripts can be downloaded from the Components for Download dashboard. For more information, see Obtaining WinRM (or DCOM) Scripts.

Next, prepare a XenDesktop master image. This procedure must be applied to all master images that are the templates of those machines that you want to monitor (for virtual applications, more specifically).

Finally, update all master images that are the templates of the virtual machines that you want to monitor.

To prepare a new XenDesktop master image for configuration:
  1. Find the virtual machine and snapshot for current master image.
  2. Optional. If you do not need to keep the changes after the last master image, revert the virtual machine to the master image snapshot.
  3. Start the virtual machine using a Remote Desktop Connection or the virtualization platform console, and follow instructions in the WinRM or DCOM script to enable a remote connection.
    Tip: The WinRM and DCOM scripts are available for download from the Components for Download dashboard. For more information, see Obtaining WinRM (or DCOM) scripts.
  4. Create a new snapshot as the new template of the master image.
To update a XenDesktop master image:
  1. Open the XenDesktop Studio.
  2. In the XenDesktop studio, in the left pane, click the Machine Catalogs node. In the right pane, select a machine catalog, and click Update Machine.
  3. On the Master Image page, select the newly prepared master image (a virtual machine snapshot), and click Next.
  4. On the Rollout Strategy page, specify how the new or updated master image is applied to the users' desktops, and click Next.
  5. On the Summary page, click Finish.

If you are using the Foglight Evolve vApp, update the Foglight Management Server SuSE firewall UDP port setting before creating a NetScaler Agent instance.

To update the SuSE firewall UDP port:
  1. In the vCenter, open the Foglight Management Server VM console vApp.
  2. Open the SuSE firewall configuration file for editing by typing the following at the command prompt:
    vi /etc/sysconfig/SuSEfirewall2
  3. In the SuSEfirewall2 file, locate the FW_SERVICES_EXT_UDP parameter and set it to the NetFlow listener port (9995 by default, this should be the same port number as the one you specify in the NetScaler Agent wizard) by typing the following:
    FW_SERVICES_EXT_UDP =”9995”
  4. Save your changes to the SuSEfirewall2 file by pressing ESC and typing the following:
    wq!
  5. Restart the SuSEfirewall service by typing the following:
    rcSuSEfirewall2 restart

From here, you can create a NetScaler Agent instance.

Configuring the Agent Manager Kerberos settings

Foglight for Citrix XenDesktop and XenApp agents use Foglight Agent Manager services to run cmdlets and queries on monitored hosts to collect data. This interface relies on Kerberos authentication. In most cases, the Agent Manager automatically generates required Kerberos configuration files. To ensure these services work as expected, after installing Foglight for Citrix XenDesktop and XenApp on the Management Server, and before running the Discover XenDesktop Infrastructure wizard, verify the Kerberos configuration on the Agent Manager. If you update any settings, restart the Agent Manager in order for these changes to take effect.

To check a Kerberos configuration file:
  1. Open one of these files for editing:

  2. In the fglam.config.xml file, locate the <config:krb5-config-file> element. It should point to the OS krb5.config file, or the Agent Manager's own krb5.config file, if the OS does not include one.

  3. Locate and open the krb5.config file for editing. You can find this file in your Agent Manager installation directory: <fglam_home>/state/default/config.

  4. In the krb5.config file, ensure that the target host’s domain (the XenDesktop Delivery Controller’s domain) is specified as the default realm. For example, if the domain is example.com, look for the following lines in the file.

    Tip
    : The KDC (Key Distribution Center) IP address (or hostname) is usually same as the Active Directory IP address (or host name).

    [libdefaults]
        default_realm = EXAMPLE.COM

    [realms]
        EXAMPLE.COM = {
        kdc = 192.0.2.0
        }

    [domain_realm]
        .example.com = EXAMPLE.COM

  5. If you make any changes to the krb5.config file, restart the Agent Manager.

    1. Log in to the Foglight browser interface.

    2. On the navigation panel, under Dashboards, choose Administration > Agents > Agent Managers.

    3. Select the row containing the Agent Manger host, and click Restart.

    For more information about this dashboard, see the Administration and Configuration Help. For more information about the Agent Manager, see the Agent Manager Guide.

Sizing recommendations

This section presents the sizing formula used to calculate the memory needed for Foglight Agent Manager and Foglight Management Server to run stable.

Sizing formula and examples for Foglight Agent Manager

VMWare® = 512 MB + 0.50 MB * Desktop(VM)#

XenDesktop® and XenApp® = 256 MB +0.25 MB * Session#

Session/Process Collection = 0.5 MB * Desktop(VM)#  

Note: The VMware agent requires a minimum of 2.5 GB of memory.

 

Example: The first line in the following table shows a XenDesktop environment with 200 desktops.

The VMware agent was set up to collect full metrics, and consumes 512 MB + 0.5 MB * 200 = 612 MB for running stable.

XenDesktop consumes 256 MB + 0.25 MB * 200 = 306 MB for running stable. 

The total cost is 612 MB + 306 MB = 918 MB of total memory.

When the Session/Process Collection is enabled, addition memory is consumed for the same environment: 200 * 0.5 = 100 MB. The total cost in this case is 918 + 100 = 1018 MB.

After the total memory (MB) is determined, you have the following two options:

  1. If "Total Memory" is less than or equal to 2560 MB, no changes are required in the Agent Manager, as the default memory of the VMware agent manifest should suffice.
  2. If "Total Memory" is greater than 2560 MB, you must change the default Agent Manager settings. The amount of additional memory required is the total memory (see "Total Memory" column in the table below) minus the default value of 2560 MB.
    In example 5, the additional memory required is: 4518 – 2560 = 1958 MB.
    1. On the agent machine, open the baseline.jvmargs.config file for editing. The file is located in the <Agent_Manager_home>/state/default/config directory.
    2. Add the following lines in the Memory Settings section:
      vmparameter.0 = "-Xms1958m";
      vmparameter.1 = "-Xmx1958m";
      Note: If this file has been previously edited, increment the numeric parameters accordingly.
    3.  Delete the existing deployed negotiation configuration settings directory: <Agent_Manager_home>/state/default/config/deployments.
    4. Restart the Agent Manager for these settings to take effect.
