Foglight™ for XenDesktop and XenApp 5.6.16 Configuration Prerequisites (4228418)

Configuring  XenDesktop System for Monitoring

To monitor XenDesktop environment, a remote connection to the XenDesktop Delivery Controller must be enabled.

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.

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 to enable a remote connection on the XenDesktop virtual machine’s master image. 

Step# 1:

Instructions:

Configuring a Remote Connection on a XenDesktop Delivery Controller

1. Obtaining a WinRM or DCOM script.

Foglight for XenDesktop and XenApp comes with the following scripts that allows to automatically configure WinRM or DCOM connection:

WinRMConfig.zip
DComConfig.zip

 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 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.

Configuring XenDesktop Master Images for Monitoring Virtual Applications

To collect the performance metrics from a virtual application, Foglight for 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.

To prepare a new XenDesktop master image for configuration:

1. Find the virtual machine and snapshot for current master image.
2. Optional. If 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.
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.

System Permissions

After a successful configuration of XenDesktop system for monitoring, ensure that the following account privileges are granted to the Delivery Controller, NetScaler, and VMware accounts that the monitoring agents will use to connect to these systems.

Performing Network Connectivity Checks

To successfully start monitoring the environment with Foglight for XenDesktop and XenApp, ensure that there are no connectivity issues between the following connection points in the environment:

• Foglight Agent Manager and NetScaler®
• Foglight Agent Manager and XenDesktop Controller

Foglight for XenDesktop and XenApp uses the following ports. Make sure they are not blocked by firewall.

If using the Foglight for Virtualization, Enterprise Edition vApp, update the Foglight Management Server SuSE firewall UDP port setting before creating a NetScaler Agent instance.

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 specify in the NetScaler Agent wizard) by typing the following:
   FW_SERVICES_EXT_UDP =”9995”
4. Save changes to the SuSEfirewall2 file by pressing ESC and typing the following:
   wq!
5. Restart the SuSEfirewall service by typing the following:
   rcSuSEfirewall2 restart
