Infrastructure Analytics

Note:

Citrix Analytics for Performance (Performance Analytics) is currently under Limited Technical Preview.

What is Infrastructure Analytics?

The Infrastructure analytics from Citrix Analytics for Performance provides insights into the status of the key components of your Citrix Virtual Apps and Desktops Sites.

  • You can view the health and status of multiple Virtual Delivery Agents (VDAs) on a single dashboard.

  • You can view the analytics of a single Site or get a cohesive view of VDA analytics across all your Sites.

  • You can view VDA usage trends over a period based on its availability, usage, and load.

This data enables you to take better-informed decisions about capacity management, perform analysis and risk assessment of your Sites. Thus, you can proactively take necessary actions to minimize critical failures and optimize the usage and performance of your Sites.

For example, as an administrator, you manage and monitor few Sites for your organization. You want to view the total number of usable VDAs across all Sites and for each Site. Use the Infrastructure dashboard to view data and its trends for the selected time period and Site.

How to access the Infrastructure dashboard

To view the Infrastructure dashboard:

  1. Log on to Citrix Cloud and select your Cloud Customer.

  2. On the Citrix Analytics Service tile, click Manage.

  3. Citrix Analytics Service opens, click the Performance tab.

  4. Click the Infrastructure tab.

How to use the Infrastructure dashboard

The Infrastructure dashboard provides the detailed status of the VDAs deployed across Sites.

The Components section provides a summary of the number and the status of VDAs and its failures across a selected Site during the selected time period. Click one of the following:

  • Multi-session OS VDAs - Get insights of the Multi-session OS VDAs available in your Sites. Multi-session OS VDAs allow multiple users to connect to the server at one time. It includes VDAs running on Windows Server OS and Windows 10 OS.

  • Single-session OS VDAs - Get insights of the Single-session OS VDAs available in your Sites. Single-session OS VDAs allow a single user to connect to the desktop at a time.

For example, in the preceding image, Multi-session OS VDAs displays the total number of VDAs as 149. 3 VDAs are in high load, 6 VDAs are in failed state, and 7 VDAs are in unregistered state. Click Multi-session OS VDAs to view detailed insights.

This section highlights the Multi-session or Single-session OS VDAs having issues, this information helps accurately track and assess health of VDAs in your environment.

The VDAs are monitored based on the following parameters.

VDAs by load

This information is available only for Multi-session OS VDAs. You can view the number of VDAs in usable state and categorized based on the load evaluator index such as high, medium, and low across all Sites or a specific Site consolidated for the selected period.

The graph displays the VDAs plotted based on the load evaluator index categorized as high, medium, and low load over the selected duration.

Monitor the load distribution trends across the VDAs over a time period.

VDAS by load

The load evaluator index for a VDA is the maximum value of the individual indexes that are enabled such as session count, CPU plus five percent of the average of the other enabled indexes. Based on the load evaluator index, you can configure load management between servers delivering Windows Server OS machines. For more information, see Load management policy settings.

The load evaluator index is categorized as follows:

  • High load: Load more than 70%

  • Medium load: Load between 30% to 70%

  • Low load: Load less than 30%

For information about how the load evaluator index is calculated, see Knowledge Center article CTX202150.

Hover over the bar graph to view the detailed status of the usable VDAs at the given time.

VDAS by load tooltip

In use + Available VDAs

This information is available for only for Single-session OS VDAs. You can view the total number of VDAs that are in use and available across all Sites or a specific Site for the selected time period. The VDA in use represents a machine that has an active session whereas available VDA is a machine with no connected sessions.

Monitor the trends for in-use and available VDAs over a time period.

Unusable VDAs

This information is available for Multi-session and Single-session OS VDAs. You can view the number of VDAs that are not in usable state across all Sites or a specific Site for the selected time period. A VDA is unusable when it is in failure state or unregistered state.

Use this information to proactively evaluate the health of the VDAs hosted in the environment and take appropriate action to rectify issues with VDAs.

A VDA can become unusable for following reasons:

  • VDA fails to communicate with Delivery Controller.

  • Broker Service experiences issues while creating a session prepare request.

  • Network issues that resulted in VDA not accepting the session prepare request.

  • A timeout occurs when VDA is attempting to register with Delivery Controller.

  • VDA might not be powered on for session launch.

  • Delivery Controller sends a request to the VDA to prepare for a connection from an end user but VDA actively refuses the request.

  • Delivery Controller does not send the required configuration data, such as policy settings and session information to the VDA during session launch.

  • VDA is removed from the Delivery Group.

  • VDA is not registered.

  • VDA power state is unavailable.

  • VDA is experiencing internal issues.

A VDA goes to unregistered state in the following scenarios:

  • VDA fails to connect and register with Cloud Connector or Delivery Controller.

  • VDA is powered off or shut down.

Monitor the trends for unregistered and failed VDAs over a time period.

VDAs unusable

Hover over the bar graph to view the detailed status of the unusable VDAs at a given time.

VDAs in use and available

Available VDAs

This information is available only for Multi-session OS VDAs. You can view the total number of VDAs that are available for use across all Sites or a specific Site for the selected time period. The available VDAs are the registered VDAs with currently no connected sessions and in idle state.

You can use this information to identify the number of unused VDAs and optimize VDA utilization across your environment.

Monitor the trends for available VDAs over a time period.

VDAs available

Hover over the bar graph to view the number of available VDAs at a given time.

VDAs available

VDAs under maintenance

This information is applicable for Multi-session and Single-session OS VDAs. You can view the number of VDAs that are in maintenance mode across all Sites or a specific Site for the selected time period. When a VDA is in maintenance mode, no new connections are allowed.

Monitor the trends for VDAs under maintenance over a time period.

VDAs maintenance

Hover over the bar graph to view the number of the VDAs in maintenance mode at that instant of time.

View by Delivery Groups

This information is available for Multi-session and Single-session OS VDAs. You can view the number of VDAs grouped by Delivery Groups and their breakup based on the states such as Unusable, Available, and Maintenance.

VDAs maintenance tooltip

This data provides you an overall status of the VDAs under the top 5 Delivery Groups sorted by the number of VDAs. Click See More Delivery Groups to see more data. By default, the table data is sorted based on the Total column that displays the total number of VDAs in the corresponding Delivery Group. You can choose to sort it based on any of the other columns.
