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

Identifying top consumers

Your monitored XenDesktop environment delivers applications to end users on demand. The Summary - All Users view identifies the users with the highest applications and desktop usage, longest logon times, and highest network latencies. This view appears in the Quick View when you select All Users in the Users view on the left. Use it to look for potential bottlenecks in your system in order to prevent potential service disruptions by reallocating system resources where they are most needed.

Investigating the levels of resource consumption

Your monitored XenDesktop® environment delivers virtual desktops and applications are delivered to end users on demand. You can review the levels of CPU and memory resources consumed by these elements, along with session-related metrics in the Summary - User view. Use it to identify the applications and desktops that consume the highest amounts of CPU and memory resources, and to look more closely at session latency and transfer rates. An application or desktop with consistently low CPU or memory utilization rates, for example, often calls for re-allocating these under used resources where they are more needed.

Monitoring Delivery Groups

A Delivery Group specifies which users can access desktops or applications based on their user type. You can monitor the performance of Delivery Groups when you select the Delivery Groups tile on the XenDesktop Environment dashboard. The information appearing in the XenDesktop DeliveryGroup Quick View can help you discover sources of performance degradation such as high number of sessions or machine failures, and to reallocate resources where they are most needed.
Figure 181. XenDesktop DeliveryGroup Quick View
To explore Delivery Groups:
1
On the navigation panel, under Dashboards, click XenDesktop Environment.
2
On the XenDesktop Environment dashboard, on the Monitoring tab, click the Delivery Groups tile.
3
In the XenDesktop DeliveryGroup Quick View, in the Delivery Groups view on the left, click a delivery group node.
The XenDesktop DeliveryGroup Quick View refreshes, showing the Summary - Application view on the right.
Figure 182. Summary - Application view
This view displays general information about the selected delivery group and shows the high-level performance trends in session counts, logon duration, machine and connection failures, and so on. For more information, see Investigating Delivery Group details.

If you want to view the relationship the selected Delivery Group has with other components in your integrated environment, in the top-right corner, click View Dependency.
The display area refreshes, showing a dependency map.

Investigating Delivery Group details

In your monitored environment, a Delivery Group is a collection of desktops and applications that can be accessed by specific end users. You can review the performance of individual Delivery Groups in the Summary - Delivery Group view. This view allows you to review general information about a selected delivery group along with performance trends in session counts, connected users, machine and connection failures. Use this view to review the general trends in the overall performance of monitored Delivery Groups and to look for any indicators that suggest potential bottlenecks. For example, an unusually high number of connection failures can affect the end-user experience and should be investigated.
