Foglight for Citrix XenDesktop and XenApp 7.3.0 - User Guide

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

Exploring and managing monitoring agents

The Agents area contains several tabs that allow you to explore and manage the agent instances that monitor your integrated XenDesktop® environment. Each tab provides information about the agents of a specific type.

Figure 5. Agents tabs

•
XenDesktop Agents and NetScaler Agents tabs: These tabs list the existing instances of the XenDesktop and NetScaler type, and allow you to manage them. These agents are provided with Foglight™ for Citrix XenDesktop and XenApp. For more information, see Managing XenDesktop and NetScaler Agent instances.
•
VMware Performance Agents tab: This tab lists any existing VMware Performance Agent instances, provided with Foglight® for VMware, if you have Foglight for VMware installed and deployed.
 
* 
TIP: Foglight for VMware allows you to monitor VMware virtual centers by tracking resource consumption of individual physical and virtual elements in your integrated environment, and alerts you of issues that are likely to compromise your system stability. For more information, see your Foglight for VMware documentation.
For each VMware Performance Agent instance, the list displays its name, the address of the monitored virtual center, and the monitored XenDesktop site name.
•
Host Agents tab: If you have Foglight for Infrastructure installed and deployed, this tab lists any existing Host Agent instances.
 
* 
TIP: Foglight for Infrastructure monitors physical hosts and helps you analyze and prevent potential performance bottlenecks. Use it to understand the state of your system health, and to track the levels of resource utilization such as CPU, network, and memory consumption for individual objects in your integrated environment. For more information, see your Foglight for Infrastructure documentation.
The list displays the hosts in your XenDesktop environment, and for each monitored host it shows the name of the Host agent, the host name, and its type. If a host is not monitored, a link is provided to launch the Add Monitored Host wizard and create a Host Agent instance. For more information about this wizard, see your Foglight for Infrastructure documentation.
•
Multi-Desktop Process/Session Collection tab: This tab lists XenDesktop sites.
For each XenDesktop site, the list displays its name, the site name, indicates if the XenDesktop Agent monitors processes and sessions, the number of desktops, when it was last updated, and the duration of the most recent collection.
•
To enable or disable the collection of process or session metrics for a site, click the Process Collection or Session Collection column, as required.
•
To see which desktops are associated with a site, click the Desktops column.

Managing XenDesktop and NetScaler Agent instances

The XenDesktop Agents and NetScaler Agents tabs list the existing agent instances of these agents and allow you to manage them. Each tab contains a set of columns that indicate various states of individual agent instances, along with several commands that you can issue to manage them. For example, to see if an agent instance is collecting data, look at the agent’s Data Collection column. A green check mark a green check mark in this column indicates that the agent is collecting data.

With the exception of the Alarms column that only appears on the XenDesktop Agents tab, the type of information appearing on these two tabs is identical.

Configuring agent properties

Foglight® uses the following agents to collect information from monitored environments:

•
XenDesktop Agent collects information about your integrated XenDesktop® environment. For information about the XenDesktop Agent properties, see the following topics:
•
Configuring XenDesktop Agent Base and OData Configuration properties
•
Configuring XenDesktop and NetScaler Agent Data Collection Scheduler properties
•
NetScaler Agent collects information about user experience data from monitored desktops, using AppFlow extensions. For information about the XenDesktopSession Agent properties, see the following topics:
•
Configuring NetScaler Agent Configuration properties
•
Configuring XenDesktop and NetScaler Agent Data Collection Scheduler properties

These agents collect data from the XenDesktop infrastructure and send it to the Management Server. They keep track of resource utilization metrics and alerts you when certain pre-defined thresholds are reached.

When an agent connects to vFoglight, it is provided with sets of properties that it uses to configure its correct running state. Each agent is provided with a combination of two types of properties: agent properties and shareable properties.

Default versions of these properties are installed with Foglight for Citrix XenDesktop and XenApp. However, you can edit the default shareable and agent properties, configure agent properties that apply only to a specific agent instance, and create edited clones of shareable properties that are used by a subset of agents of a certain type.

For detailed information about working with agent properties, see the Administration and Configuration Help.

To modify agent properties:
1
Log in to the Foglight browser interface.
2
Open the Agent Status dashboard and navigate to the agent properties.
a
On the navigation panel, under Dashboards, choose Administration > Agents > Agent Status.
b
On the Agent Status dashboard, select a XenDesktop or XenDesktop Session agent instance whose properties you want to modify, and click Edit Properties.
c
Click Modify the private properties for this agent.
The agent properties appears in the display area.
