Foglight for Citrix XenDesktop and XenApp 5.7.2 - User Guide

Getting started Setting up data collection agents Monitoring the performance of your XenDesktop environment

Monitoring the performance of your XenDesktop environment

When you deploy Foglight™ for Citrix XenDesktop and XenApp and set up the monitoring agents for data collection, the XenDesktop Environment dashboard enables you to review the performance of your environment at a glance. use this dashboard to ensure consistent application performance, by drilling down for details about individual components, to look for the indicators of performance degradation, such as high CPU load or network utilization.
A typical XenDesktop® environment contains a set of servers, delivery groups, desktops, and applications. You can view the overall state of these components on the XenDesktop Environment dashboard. To access this dashboard, under Dashboards, click XenDesktop.

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.
•
StoreFronts represent services that provide users with access to applications and desktops.
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.

Figure 46. Exploring License Servers, Controllers, and Storefronts
The resulting view helps you understand the state of the resources of the host on which the License Server, Controller, or Storefront 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.

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.
Figure 49. Summary - XenDesktop Site view
 
Table 3. Summary - XenDesktop Site view
Properties
Configuration details for the monitored XenDesktop Site: the name of the selected XenDesktop Site, the name of the XenDesktop application running on the monitored Site, the XenDesktop application edition, the XenDesktop version number, the type of the license model implemented at the monitored XenDesktop site, and the number of unregistered desktops. Citrix XenDesktop communicates with the controller in the monitored XenDesktop site using the Virtual Delivery Agent (VDA), and this state is referred to as being registered with the controller. A communication failure prevents XenDesktop to establish connection with the affected virtual desktops, causing them to turn into wasted resources. This information can help you troubleshoot problems related to an unsuccessful VDA registration.
