Foglight for Citrix XenDesktop and XenApp 6.0.0 - User Guide

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

Managing Certificates for NetScaler Agent

When upgrading external Agent Manager, if the new Agent Manager uses a higher version JRE than the old Agent Manager, the JRE TrustStore (caserts) in the old Agent Manager will be replaced by the new TrustStore from the higher version JRE. This will cause all the custom certificates imported to the old JRE TrustStore by customers get lost after the Agent Manager upgrade.

2
If yes, copy the file <fglam_home>/jre/<current_jre_version>/jre/lib/security/cacerts to a local directory before upgrading Agent Manager.

As for the embedded Agent Manager, it uses the same JRE as the Management Server. If there are custom JRE certificates stored in JRE TrustStore and a higher JRE version is used, back up the JRE cacert TrustStore used by the Management Server before upgrading Management Server.

Below is a list of JRE versions used by Agent Manager on various platforms in this release.

 

NOTE: If the certificate is not Base64 format, use openssl command to convert the certificate file into a Base64 file. Use either of the following commands depending on the source form:
openssl x509 -inform DER -in xxx.cer -out xxx.crt
or
openssl x509 -inform PEM -in xxx.cer -out xxx.crt
The alias is required and is used in the list and delete operations to refer to the certificate. It can be anything.

Print out a list of certificates and the aliases that refer to them.

Refer to the example output below:

Remove a certificate referred to by an alias.

 

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.

The XenDesktop Environment dashboard provides a set of tabs, each displaying a different aspect of your monitored system.

Monitoring: Use this tab to review data specific to the main components of your monitored environment such as servers, delivery groups, desktops, applications, sessions, or vSphere resources. When you navigate to the XenDesktop Environment dashboard for the first time, the Monitoring tab appears open. This tab provides an overall summary of your monitored environment. It is described in this section.
Reports: Use this tab to run and schedule Foglight for Citrix XenDesktop and XenApp reports. For more information, see Generating reports.
FAQts: Use this tab to review the answers to common questions about your monitored systems. For more information, see Reviewing Frequently Asked Questions.
Administration: Use this tab to discover XenDesktop® hosts, and to manage XenDesktop Agent instances. For more information, see Setting up data collection agents .
Getting Started: Use this tab to activate, purchase, or renew your Foglight license. For more information, see Activating Foglight for Citrix XenDesktop and XenApp licenses.

A set of tiles along the top of the Monitoring tab gives you a quick overview of the monitored objects: servers, delivery groups, desktops, applications, sessions, and vSphere® resources. Each tile represents a collection of a specific object type, shows the object count, and the count of objects in each alarm state (Normal, Warning, Critical, and Fatal).

The Quick View appearing immediately below the tiles allows you to select a specific instance of the tile selection. From here, you can drill down on a desired object instance, and review the related monitoring metrics.

If any alarms are generated against certain types of monitored objects, they appear on the Monitoring tab, along the bottom of the summary view on the right. Drill down on an alarm to find out what triggered it, and to take steps to investigate further.

For complete information about alarms in Foglight for Citrix XenDesktop and XenApp, see the Foglight for Citrix XenDesktop and XenApp User Guide.

Activating Foglight for Citrix XenDesktop and XenApp licenses

Foglight for Citrix 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 Citrix XenDesktop and XenApp license when your existing trial or commercial license expires. For more information, see the Foglight for Citrix 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.
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.

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.
The XenDesktop Infrastructure Quick View refreshes, showing the summary information about the selected component on the right.
When the Application tile on left is selected this view shows the list of services running on the selected License Server or Delivery Controller, and displays any alarms associated with it.
When you select Guest, the view shows the usage of system resources on the machine on which the selected License Server or Delivery Controller is running.
Delivery Group View: A Delivery Group specifies which users can access Desktops or Applications based on their user type. This tab illustrates the relationships between main components associated with the Delivery Groups that belong to the selected XenDesktop site, including any Delivery Groups, Desktops, and Applications provided by the Delivery Groups.
Infrastructure View: This tab illustrates the relationships between main infrastructure elements components associated with the Delivery Groups that belong to the selected XenDesktop site, such as the NetScaler Gateway, StoreFront Server, Delivery Controller, Domain Controller Database, and the License Server.
