Monitor Sites

With full administrator permissions, when you open Director, the Dashboard provides a centralized location to monitor the health and usage of a Site.

localized image

If there are currently no failures and no failures have occurred in the past 60 minutes, panels stay collapsed. When there are failures, the specific failure panel automatically appears.

Note: Depending on your organization's license and your Administrator privileges, some options or features might not be available.
Panel Description

User Connection Failures

Connection failures over the last 60 minutes. Click the categories next to the total number to view metrics for that type of failure. In the adjacent table, that number is broken out by Delivery Groups. Connection failures includes failures caused by application limits being reached. For more information on application limits, see Applications.

Failed Desktop OS Machines or Failed Server OS Machines Total failures in the last 60 minutes broken out by Delivery Groups. Failures broken out by types, including failed to start, stuck on boot, and unregistered. For Server OS machines, failures also include machines reaching maximum load.
Licensing Status
  • License Server alerts display alerts sent by the License Server and the actions required to resolve the alerts.
    Requires License Server Version 11.12.1 or later.
  • Delivery Controller alerts display the details of the licensing state as seen by the Controller and are sent by the Controller.
    Requires Controller for XenApp 7.6 or XenDesktop 7.6 or later.
You can set the threshold for alerts in Studio.
Sessions Connected Connected sessions across all Delivery Groups for the last 60 minutes.
Average Logon Duration Logon data for the last 60 minutes. The large number on the left is the average logon duration across the hour.

Logon data for VDAs earlier than XenDesktop 7.0 is not included in this average.

For more information, see Diagnose user logon issues.

Infrastructure

Lists your Site's infrastructure - hosts and Controllers. 

For infrastructure from XenServer or VMware, you can view performance alerts.

For example, you can configure XenCenter to generate performance alerts when CPU, network I/O, or disk I/O usage go over a specified threshold on a managed server or virtual machine. By default, the alert repeat interval is 60 minutes, but you can configure this as well. For details, in the Citrix XenServer 7.0 Administrator's Guide, see XenCenter Performance Alerts.

Note: If no icon appears for a particular metric, this indicates that this metric is not supported by the type of host you are using. For example, no health information is available for System Center Virtual Machine Manager (SCVMM) hosts, AWS and CloudStack.

Continue to troubleshoot issues using these options (which are documented below):

Monitor sessions

If a session becomes disconnected, it is still active and its applications continue to run, but the user device is no longer communicating with the server.

Action Description

View a user's currently connected machine or session

From the Activity Manager and User Details views, view the user's currently connected machine or session and a list of all machines and sessions to which this user has access. To access this list, click the session switcher icon in the user title bar. For more information, see Restore sessions.

View the total number of connected sessions across all Delivery Groups

From the Dashboard, in the Sessions Connected pane, view the total number of connected sessions across all Delivery Groups for the last 60 minutes. Then click the large total number, which opens the Filters view, where you can display graphical session data based on selected Delivery Groups and ranges and usage across Delivery Groups.

End idle sessions

The Sessions Filters view displays data related to all active sessions. Filter the sessions based on Associated User, Delivery Group, Session State, and Idle Time greater than a threshold time period. From the filtered list, select sessions to log off or disconnect. For more information, see Troubleshoot applications.

View data over a longer period of time

On the Trends view, select the Sessions tab to drill down to more specific usage data for connected and disconnected sessions over a longer period of time (that is, session totals from earlier than the last 60 minutes). To view this information, click View historical trends

Note: If the user device is running a legacy Virtual Delivery Agents (VDA), such as a VDA earlier than version 7, or a Linux VDA, Director cannot display complete information about the session. Instead, it displays a message that the information is not available.

View the transport protocol in use for the HDX connection type for the current session in the Session Details panel. This information is available for sessions launched on VDAs Version 7.13 or later.

localized image
  • For HDX Connection type,
    • The Protocol is displayed as UDP, if EDT is used for the HDX connection.
    • The Protocol is displayed as TCP, if TCP is used for the HDX connection.
  • For RDP Connection type, the Protocol is displayed as n/a.

When adaptive transport is configured, the session transport protocol dynamically switches between EDT (over UDP) and TCP, based on the network conditions. If the HDX session cannot be established using EDT, it falls back to the TCP protocol.

For more information about adaptive transport configuration, see Adaptive Transport.

Filter data to troubleshoot failures

When you click numbers on the Dashboard or select a predefined filter from the Filters menu, the Filters view opens to display the data based on the selected machine or failure type.

Predefined filters cannot be edited, but you can save a predefined filter as a custom filter and then modify it. Additionally, you can create custom filtered views of machines, connections, and sessions across all Delivery Groups.

  1. Select a view:
    • Machines. Select Desktop OS Machines or Server OS Machines. These views show the number of configured machines. The Server OS Machines tab also includes the load evaluator index, which indicates the distribution of performance counters and tool tips of the session count if you hover over the link.
    • Sessions. You can also see the session count from the Sessions view. Use the idle time measurements to identify sessions that are idle beyond a threshold time period.
    • Connections. Filter connections by different time periods, including last 60 minutes, last 24 hours, or last 7 days.
    • Application Instances. This view displays the properties of all application instances on VDAs of Server and Desktop OS. The session idle time measurements are available for Application instances on VDAs of Server OS. 
  2. For Filter by, select the criteria.
  3. Use the additional tabs for each view, as needed, to complete the filter.
  4. Select additional columns, as needed, to troubleshoot further.
  5. Save and name your filter. 
  6. To access filters from multiple Director servers, store the filters on a shared folder accessible from those servers:
    • The shared folder must have modify permissions for accounts on the Director server. 
    • The Director servers must be configured to access the shared folder. To do this, run IIS Manager. In Sites > Default Web Site > Director> Application Settings, modify the Service.UserSettingsPath setting to reflect the UNC path of the shared folder.
  7. To open the filter later, from the Filters menu, select the filter type (Machines, Sessions, Connections, or Application Instances), and then select the saved filter.
  8. If needed, for Machines or Connections views, use power controls for all the machines you select in the filtered list. For the Sessions view, use the session controls or option to send messages.
  9. In the Machines and Connections views, click the Failure Reason of a failed machine or connection to get a detailed description of the failure and actions recommended to troubleshoot the failure. The failure reasons and the recommended actions for Machine and Connection failures are available in the Citrix Director 7.12 Failure Reasons Troubleshooting Guide.
  10. In the Machines view, click on a machine name link to go to the corresponding Machine Details page. This page displays the details of the machine, provides power controls, displays the CPU, memory, disk monitoring, and GPU monitoring graphs. Also, click View Historical Utilization to see the resource utilization trends for the machine. For more information, see Troubleshoot machines.
  11. In the Application Instances view, sort or filter based on Idle Time greater than a threshold time period. Select the idle application instances to end. Log off or Disconnect of an application instance ends all active application instances in the same session. For more information, see Troubleshoot applications.
    Note: The Application Instances filter page and idle time measurements in the Sessions filter pages are available if Director, Delivery Controller(s), and VDAs are version 7.13 or later. 

Monitor historical trends across a Site

The Trends view accesses historical trend information for sessions, connection failures, machine failures, logon performance, load evaluation, capacity management, machine usage and resource utilization for each Site. To locate this information, click Trends Menu.

The zoom-in drill down feature lets you navigate through trend charts by zooming in on a time period (clicking on a data point in the graph) and drilling down to see the details associated with the trend. This feature enables you to better understand the details of who or what has been affected by the trends being displayed.

To change the default scope of each graph, apply a different filter to the data.

Choose a time period for which you require the historical trend information; time period availability depends on your Director deployment as follows: 

  • Trend reports of up to last year (365 days) are available in Platinum licensed Sites. 
  • Trend reports of up to last month (31 days) are available in Enterprise licensed Sites.
  • Trend reports of up to last 7 days in non-Platinum and non-Enterprise licensed Sites.

Note:

  • In all Director deployments, Sessions, failures, and logon performance trend information is available as graphs and tables when the time period is set to Last month or shorter. When the time period is set to Last Year, the trend information is available as graphs but not as tables.
  • The default values of the trends data grooming retention by the Monitoring Service are available in the Data granularity and retention section in Accessing data using the API. Customers on Platinum licensed Sites can change the grooming retention to their desired number of retention days.

You can drill down to the machine, and view data and charts for the top 10 processes consuming CPU. Filter by Delivery Group and Time period. CPU, memory usage, and peak concurrent sessions graphs are available for the last 2 hours, 24 hours, 7 days, month, and year. The average IOPS and disk latency graphs are available for the last 24 hours, month, and year. 
Note:

  • The Monitoring policy setting, Enable Process Monitoring, must be set to "Allowed" to collect and display data in the Top 10 Processes table on the Historic Machine Utilization page. The policy is set to "Prohibited" by default.
  • All resource utilization data is collected by default. This can be disabled using the Enable Resource Monitoring policy setting.  

The table below the graphs shows the resource utilization data per machine. 
Note: Average IOPS shows the daily averages. Peak IOPS is calculated as the highest of the IOPS averages for the selected time range. (An IOPS average is the hourly average of IOPS collected during the hour on the VDA). 

View network analysis data

Note: The availability of this feature depends on your organization's license and your administrator permissions. This feature requires Delivery Controller(s) version 7.11 or later.
From the Network tab, monitor your network analysis, which provides a user, application, and desktop contextual view of the network. With this feature, Director provides advanced analytics of ICA traffic in your deployment through HDX Insight reports from NetScaler Insight Center or NetScaler MAS. For more information, see Configure network analysis.

Create customized reports

The Custom Reports tab provides a user interface for generating Custom Reports containing real-time and historical data from the Monitoring database in tabular format.
Note: This feature requires Delivery Controller(s) version 7.12 or later.
From the list of previously saved Custom Report queries, you can execute to export the report in CSV format, copy and share the corresponding OData query, or edit the query.
You can create a new Custom Report query based on machines, connections, sessions, or application instances. Specify filter conditions based on fields such as machine, delivery group, or time period. Specify additional columns required in your Custom Report. Preview displays a sample of the report data. Saving the Custom Report query adds it to the list of saved queries.
You can create a new Custom Report query based on a copied OData query. To do this, select the OData Query option and paste the copied OData query. You can save the resultant query for execution later.
Note: The column names in Preview and Export report generated using OData queries are not localized, but appear in English.

The flag icons on the graph indicate significant events or actions for that specific time range. Hover the mouse over the flag and click to list events or actions.

Note: HDX connection logon data is not collected for VDAs earlier than 7. For earlier VDAs, the chart data is displayed as 0.

Export reports

You can export trends data to generate regular usage and capacity management reports. Export supports PDF, Excel, and CSV report formats. Reports in PDF and Excel formats contain trends represented as graphs and tables. CSV format reports contain tabular data that can be processed to generate views or can be archived. 

To export a report:

  1. Go to the Trends tab.
  2. Set filter criteria and time period and click Apply. The trend graph and table are populated with data.
  3. Click Export and enter name and format of the report.

Director generates the report based on the filter criteria you select. If you change the filter criteria, click Apply before you click Export.

Note: Export of a large amount of data causes a significant increase in memory and CPU consumption in the Director server, the Delivery Controller, and the SQL servers. The supported number of concurrent export operations and the amount of data that can be exported is set to default limits to achieve optimal Export performance.

To change the limit of the number of records you can export:

  1. Open the IIS Manager console.
  2. Go to the Director website under the Default website.
  3. Double-click Application Settings.
  4. Edit the field or add a new field.

Adding these field values in Application Settings, overrides the default values.

Warning: Setting field values higher than the max number of records supported, can impact the performance of Export and is not supported.

Error Handling

This section gives you information on dealing with errors that you might encounter during Export operation.

  • Director has timed out

This error could occur due to network issues or high resource usage on the Director server or with the Monitor Service.

The default timeout duration is 100 seconds. To increase the timeout duration of the Director Service, set the value of Connector.DataServiceContext.Timeout field in Director Application Settings in Internet Information Services (IIS):

1. Open the IIS Manager console.

2. Go to the Director website under the Default website.

3. Double-click Application Settings.

4. Edit the value Connector.DataServiceContext.Timeout

  • Monitor has timed out

This error could occur due to network issues or high resource usage with the Monitor Service or on the SQL server.

To increase the timeout duration of the Monitor Service, run the following PowerShell commands on the Delivery Controller:

command Copy

asnp Citrix.*

Get-MonitorConfiguration

Set-MonitorConfiguration -MonitorQueryTimeoutSeconds <timeout value>

  • Max concurrent Export or Preview operations ongoing

Director supports one instance of Export or Preview. If you get the Max concurrent Export or Preview operations ongoing error, try the next Export operation again later.

It is possible to increase the number of concurrent Export or Preview operations, however this can impact the performance of Director and is not supported:

1. Open the IIS Manager console.

2. Go to the Director website under the Default website.

3. Double-click Application Settings.

4. Edit the value UI.ConcurrentExportLimit.

  • Insufficient disk space in Director

Each Export operation requires a maximum of 2GB hard disk space in the Windows Temp folder. Retry Export after clearing space or adding more hard disk space on the Director server.

Monitor hotfixes

To view the hotfixes installed on a specific machine VDA (physical or VM), choose the Machine Details view.

Control user machine power states

To control the state of the machines that you select in Director, use the Power Control options. These options are available for Desktop OS machines, but might not be available for Server OS machines.

Note: This functionality is not available for physical machines or machines using Remote PC Access.
Command Function
Restart Performs an orderly (soft) shutdown of the VM and all running processes are halted individually before restarting the VM. For example, select machines that appear in Director as "failed to start," and use this command to restart them.
Force Restart Restarts the VM without first performing any shut-down procedure. This command works in the same way as unplugging a physical server and then plugging it back in and turning it back on.
Shut Down Performs an orderly (soft) shutdown of the VM; all running processes are halted individually.
Force Shutdown Shuts down the VM without first performing any shut-down procedure. This command works in the same way as unplugging a physical server. It might not always shut down all running processes, and you risk losing data if you shut down a VM in this way.
Suspend Suspends a running VM in its current state and stores that state in a file on the default storage repository. This option allows you to shut down the VM's host server and later, after rebooting it, resume the VM, returning it to its original running state.
Resume Resumes a suspended VM and restores its original running state.
Start Starts a VM when it is off (also called a cold start).

If power control actions fail, hover the mouse over the alert, and a pop-up message appears with details about the failure.

Prevent connections to machines

Use maintenance mode to prevent new connections temporarily while the appropriate administrator performs maintenance tasks on the image.

When you enable maintenance mode on machines, no new connections are allowed until you disable it. If users are currently logged on, maintenance mode takes effect as soon as all users are logged off. For users who do not log off, send a message informing them that machines will be shut down at a certain time, and use the power controls to force the machines to shut down.

  1. Select the machine, such as from the User Details view, or a group of machines in the Filters view.
  2. Select Maintenance Mode, and turn on the option.

If a user tries to connect to an assigned desktop while it is in maintenance mode, a message appears indicating that the desktop is currently unavailable. No new connections can be made until you disable maintenance mode.
