Getting Started Setting Up Data Collection Agents Monitoring the Performance of your XenDesktop Environment

Activating Foglight for XenDesktop and XenApp Licenses

Foglight for XenDesktop and XenApp is license-protected. When you install it for the first time, it comes with a 40-day trial license. You can activate it using the Getting Started tab. You can also use this tab to purchase or renew your Foglight for XenDesktop and XenApp license when your existing trial or commercial license expires. For more information, see the Foglight for XenDesktop and XenApp Release Notes.

Investigating the Performance of XenDesktop Infrastructure Components

A typical XenDesktop® infrastructure consists the following high-level components:
•
XenDesktop Site represents your monitored XenDesktop environment, consisting of Delivery Controllers, virtual desktops that they distribute to end-users, and other associated components.
•
Delivery Controllers distribute virtual desktops to end-users, manage user access, and optimize connections.
•
License servers allow Citrix® licenses to be shared among application components.
You can monitor the performance of these components when you select the XenDesktop Infrastructure tile on the XenDesktop Environment dashboard.
The information appearing in the XenDesktop Infrastructure Quick View can help you discover potential resource-level issues such as spikes in session trends, and to reallocate resources where they are most needed.

To explore XenDesktop Sites, Delivery Controllers, and License Servers:
1
On the navigation panel, under Dashboards, click XenDesktop Environment.
2
On the XenDesktop Environment dashboard, on the Monitoring tab, click the XenDesktop Infrastructure tile.
3
In the XenDesktop Infrastructure Quick View, in the XenDesktop Infrastructure view on the left, click Site Overview.
The XenDesktop Infrastructure Quick View refreshes, showing the Summary - XenDesktop Site view on the right.
Figure 37. XenDesktop Infrastructure Quick View
This view displays general information about the monitored XenDesktop site and shows the high-level performance trends in session counts, logon duration, machine and connection failures, and so on. For more information, see Exploring XenDesktop Sites.
4
In the left pane, select a License Server or a Delivery Controller.
The XenDesktop Infrastructure Quick View refreshes, showing a summary view on the right (Summary - License Server or Summary - Delivery Controller).

For more information, see Investigating the Use of License Server and Delivery Controller Resources.
5
Explore a License Server or Controller in more detail. In the top-right corner of the view, click Explore.
The display area refreshes.
Figure 41. Exploring License Servers
The resulting view helps you understand the state of the resources of the host on which the License Server or Controller is running, if that host is already monitored with Foglight™ for Infrastructure. You can observe how the existing resource levels affect your monitored system as a whole. Along with displaying the system, network, CPU, memory, disk usage metrics, and any related alarms, this intuitive dashboard connects these visual elements with a series of graphical flows that illustrate how quickly the hosts transmits and processes data in real time. For example, you can review the rates of incoming and outgoing data and how they affect your network resources.
For more information, see Exploring Individual License Servers and Controllers.

TIP: To return to the XenDesktop Environment dashboard, use the bread crumb trail in the top-left corner.

Exploring XenDesktop Sites

A XenDesktop Site represents your monitored XenDesktop® environment, consisting of Delivery Controllers, virtual desktops, and other associated components. The Summary - XenDesktop Site view allows you to review general information about the monitored XenDesktop site along with performance trends in session counts, logon duration, machine and connection failures. Use this view to review the general trends in the overall performance of your monitored XenDesktop site and to look for any indicators that suggest potential bottlenecks. For example, an unusually high number of connection errors can affect the end-user experience and should be investigated.

Investigating the Use of License Server and Delivery Controller Resources

In your monitored environment, a Citrix License Server allows Citrix® licenses, including XenDesktop® licenses, to be shared among application components. Delivery Controllers distribute virtual desktops to end-users, manage user access, and optimize connections. You can review the performance of these components in the Summary - License Server and Summary - Delivery Controller views.
These views have two different layouts, depending on the tile selected on the left:
•
Application view
•
Guest view
