Citrix Scout 编辑

Introduction

Citrix Scout collects diagnostics and runs health checks. You can use the results for proactive maintenance in your Citrix Virtual Apps and Desktops deployment. Citrix offers comprehensive, automated analysis of diagnostics collections through Citrix Insight Services. You can also use Scout to troubleshoot issues, on your own or with Citrix Support guidance.

You can upload collection files to Citrix for analysis and guidance from Citrix Support. Or, you can save a collection locally for your own review, and then later upload the collection file to Citrix for analysis.

Scout offers the following procedures:

• Collect: Runs a one-time diagnostics collection on machines you select in a site. You can then either upload the file to Citrix or save it locally.
• Trace & Reproduce: Starts a manual trace on machines you select. Then you re-create issues on those machines. After re-creating the issue, the trace is stopped. Scout then collects other diagnostics and uploads the file to Citrix, or saves the file locally.
• Schedule: Schedules diagnostics collections to occur daily or weekly at a specified time on machines you select. The file is automatically uploaded to Citrix.
• Health Check: Runs checks that gauge the health and availability of the site and its components. You can run health checks for Delivery Controllers, VDAs, StoreFront servers, and Citrix License Servers. If issues are found during the checks, Scout provides a detailed report. Each time Scout starts, it checks for updated health check scripts. If new versions are available, Scout downloads them automatically, for use the next time health checks are run.

The graphical interface described in this article is the primary way to use Scout. Alternatively, you can use PowerShell to configure one-time or scheduled diagnostic collections and uploads. See Call Home.

Where to run Scout:

• In an on-premises deployment, run Scout from a Delivery Controller to capture diagnostics or run checks on one or more Virtual Delivery Agents (VDAs), Delivery Controllers, StoreFront servers, and License Servers. You can also run Scout from a VDA to collect local diagnostics.
• In a Citrix Cloud environment that uses the Citrix Virtual Apps and Desktops service, run Scout from a VDA to collect local diagnostics.

The log for the Scout application is stored in C:\ProgramData\Citrix\TelemetryService\ScoutUI.log. This file can be used for troubleshooting.

What is collected

The diagnostics collected by Scout include Citrix Diagnostic Facility (CDF) trace log files. A subset of CDF traces called Always-on Tracing (AOT) is also included. AOT information can be helpful when troubleshooting common issues such as VDA registrations and application/desktop launches. No other Event Tracing for Windows (ETW) information is collected.

The collection includes:

• Registry entries created by Citrix Virtual Apps and Desktops under HKEY\_LOCAL\_MACHINE\\SOFTWARE\\CITRIX.
• Windows Management Instrumentation (WMI) information under the Citrix namespace.
• Processes that are running.
• Crash dumps of Citrix processes that are stored in %PROGRAM DATA%\Citrix\CDF.
• Citrix policy information, in CSV format.
• Installation and upgrade information. The collection can include the full product metainstaller log, failing MSI logs, output from the MSI log analyzer, StoreFront logs, Licensing compatibility check logs, and results from preliminary site upgrade tests.

About trace information:

• The trace information is compressed as it is collected, keeping a small footprint on the machine.
• On each machine, the Citrix Telemetry Service keeps compressed recent trace information for a maximum of eight days.
• Beginning with Citrix Virtual Apps and Desktops 7 1808, AOT traces are saved to the local disk by default. (In earlier versions, traces were held in memory.) Default path = C:\Users\CitrixTelemetryService\AppData\Local\CitrixAOT.
• Beginning with Citrix Virtual Apps and Desktops 7 1811, AOT traces saved to network shares are collected with other diagnostics.
• You can modify the maximum size (default = 10 MB) and slice duration, using the Enable-CitrixTrace cmdlet or the HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Telemetry DefaultListen registry string.
• Traces append to the file until the file reaches 10% of MaxSize.

For a list of the datapoints that Scout collects, see Call Home key datapoints.

About health checks

Health check data is stored in folders under C:\ProgramData\Citrix\TelemetryService\.

Site health checks

Site health checks are included in the Environment Test Service, which provides a comprehensive evaluation of the FlexCast Management Architecture (FMA) services. In addition to checking for service availability, these checks look for other health indicators such as database connections.

Site health checks run on Delivery Controllers. Depending on your site’s size, these checks can take up to an hour to complete.

Delivery Controller configuration checks

As part of the site health checks. Delivery Controller configuration checks verify whether the following issues exist, based on Citrix recommendations for Virtual Apps and Desktops sites:

• One or more Delivery Controllers are in a failed state.
• There is only one Delivery Controller in the site.
• Delivery Controllers are of different versions.

In addition to meeting the permissions and requirements for health checks, Delivery Controller configuration checks require:

• At least one Controller powered on.
• The Broker Service running on a Controller.
• A working connection from the Controller to the site database.

VDA health checks

VDA health checks identify possible causes for common VDA registration, session launch, and time zone redirection issues.

For registration on the VDA, Scout checks:

• VDA software installation
• VDA machine domain membership
• VDA communication port availability
• VDA service status
• Windows firewall configuration
• Communication with Controller
• Time sync with Controller
• VDA registration status

For session launch on VDAs, Scout checks:

• Session launch communication port availability
• Session launch services status
• Session launch Windows firewall configuration
• VDA Remote Desktop Services Client Access Licenses
• VDA application launch path

For time zone redirection on VDAs, Scout checks:

• Windows hotfix installation
• Citrix hotfix installation
• Microsoft group policy settings
• Citrix group policy settings

StoreFront health checks

StoreFront checks verify:

• Citrix Default Domain service is running
• Citrix Credential Wallet service is running
• Connection from the StoreFront server to Active Directory port 88
• Connection from the StoreFront server to Active Directory port 389
• Base URL has a valid FQDN
• Correct IP address from the base URL can be retrieved
• IIS application pool is using .NET 4.0
• Whether the certificate is bound to the SSL port for the host URL
• Whether the certificate chain is complete
• Whether certificates have expired
• Whether a certificate is expiring soon (within 30 days)

License Server checks

License Server checks verify:

• License Server connection from the Delivery Controller
• License Server firewall remote access status
• Citrix Licensing service status
• License Server grace period state
• License Server ports connection
• Whether the Citrix vendor daemon (CITRIX) is running
• Whether system clocks are synchronized
• Whether the Citrix Licensing service is running under the Local Service account
• Presence of the CITRIX.opt file
• Customer Success Services eligibility date
• Citrix License Server Update
• Whether the License Server certificate is in the Delivery Controller’s trusted root store

In addition to meeting the permissions and requirements for health checks, the License Server must be joined to a domain. Otherwise, the License Server won’t be discovered.

Permissions and requirements

Permissions:

• To collect diagnostics:

  • You must be a local administrator and domain user for each machine from which you’re collecting diagnostics.
  • You must have permission to write to the LocalAppData directory on each machine.

• To run health checks:

  • You must be a member of the domain users group.
  • You must be either a full administrator or have a custom role with read-only and Run Environment Tests permissions for the site.

• Use Run as administrator when launching Scout.

For each machine from which you collect diagnostics or run health checks:

• Scout must be able to communicate with the machine.
• File and printer sharing must be turned on.
• PSRemoting and WinRM must be enabled. The machine must also be running PowerShell 3.0 or later.
• The Citrix Telemetry Service must be running on the machine.
• Windows Management Infrastructure (WMI) access must be enabled on the machine.
• To set a schedule for diagnostic collection, the machine must be running a compatible Scout version.

Do not use the dollar sign ($) in user names specified in pathnames. It prevents the collection of diagnostic information.

Scout runs verification tests on the machines you select, to make sure these requirements are met.

Verification tests

Before a diagnostic collection or health check starts, verification tests run automatically for each selected machine. These tests make sure that the requirements are met. If a test fails for a machine, Scout displays a message, with suggested corrective actions.

• Scout cannot reach this machine: Ensure that:

  • The machine is powered-on.
  • The network connection is working properly. (This can include verifying that your firewall is properly configured.)
  • File and printer sharing is turned on. See the Microsoft documentation for instructions.
• Enable PSRemoting and WinRM: You can enable PowerShell remoting and WinRM at the same time. Using Run as administrator, run the Enable-PSRemoting cmdlet. For details, see the Microsoft help for the cmdlet.
• Scout requires PowerShell 3.0 (minimum): Install PowerShell 3.0 (or later) on the machine, and then enable PowerShell remoting.
• Unable to access LocalAppData directory on this machine: Ensure that account has permission to write to the LocalAppData directory on the machine.
• Cannot locate Citrix Telemetry Service: Ensure that the Citrix Telemetry Service is installed and started on the machine.
• Cannot get schedule: Upgrade the machine to (minimum) XenApp and XenDesktop 7.14.
• WMI is not running on the machine: Ensure that Windows Management Instrumentation (WMI) access is enabled.
• WMI connections blocked: Enable WMI in the Windows Firewall service.
• Newer version of Citrix Telemetry Service required: (Version is checked only for Collect and Trace & Reproduce.) Upgrade the Telemetry Service version on the machine (see Install and upgrade). If you do not upgrade the service, that machine won’t be included in the Collect or Trace & Reproduce actions.

Version compatibility

This version of Scout (3.x) is intended to be run on Citrix Virtual Apps and Desktops (or minimum XenApp and XenDesktop 7.14) Controllers and VDAs.

An earlier version of Scout is provided with XenApp and XenDesktop versions earlier than 7.14. For information about that earlier version, see CTX130147.

If you upgrade a Controller or VDA earlier than 7.14 to version 7.14 (or a later supported version), the earlier version of Scout is replaced with the current version.

Install and upgrade

By default, Scout is installed or upgraded automatically as part of the Citrix Telemetry Service when you install or upgrade a VDA or a Controller.

If you omit the Citrix Telemetry Service when you install a VDA, or remove the service later, run TelemetryServiceInstaller_xx.msi from the x64\Virtual Desktop Components or x86\Virtual Desktop Components folder on the Citrix Virtual Apps and Desktops installation media.

When you select the Collect or Trace & Reproduce action, you’re notified if a machine is running an older version of the Citrix Telemetry Service. Citrix recommends using the latest supported version. If you don’t upgrade the Telemetry Service on that machine, it won’t participate in the Collect or Trace & Reproduce actions. To upgrade the Telemetry Service, use the same procedure as installing it.

Upload authorization

If you plan to upload diagnostic collections to Citrix, you must have a Citrix or Citrix Cloud account. (These are the credentials you use to access Citrix downloads or access the Citrix Cloud Control Center.) After your account credentials are validated, a token is issued.

• If you authenticate with a Citrix account, the token-issuing process isn’t visible. You simply enter your account credentials. After Citrix validates the credentials, you can then continue in the Scout wizard.
• If you authenticate with a Citrix Cloud account, you click a link to access Citrix Cloud using HTTPS with your default browser. After you enter your Citrix Cloud credentials, the token is displayed. Copy the token and then paste it into Scout. You can then continue in the Scout wizard.

The token is stored locally on the machine where you’re running Scout. To enable use of that token the next time you run Collect or Trace & Reproduce, select the Store token and skip this step in the future check box.

You must reauthorize each time you select Schedule on the Scout opening page. You cannot use a stored token when creating or changing a schedule.

Use a proxy for uploads

If you want to use a proxy server to upload collections to Citrix, you can instruct Scout to use the proxy settings configured for your browser’s Internet Properties. Alternatively, you can specify the proxy server’s IP address and port number.

Add machines manually

After Scout lists the Controllers and VDAs it discovers, you can manually add other machines in the deployment, such as StoreFront servers, License Servers, and Citrix Provisioning servers.

When running health checks:

• Citrix License Servers in the domain are discovered automatically. You cannot add License Servers manually.
• Health checks do not currently support Citrix Provisioning servers.

On any Scout page that lists the discovered machines, click + Add machine. Type the FQDN of the machine you want to add, and then click Continue. Repeat to add other machines, as needed. (Although entering a DNS alias instead of an FQDN can appear valid, the health checks might fail.)

Manually added machines always appear at the top of the machines list, above the discovered machines.

An easy way to identify a manually added machine is the red delete button on the right end of the row. Only manually added machines have that button. Discovered machines don’t.

To remove a manually added machine, click the red button on the right end of the row. Confirm the deletion. Repeat to delete other manually added machines.

Scout remembers manually added machines until you remove them. When you close and then reopen Scout, the manually added machines are still listed at the top of the list.

CDF traces are not collected when using Trace & Reproduce on StoreFront servers. However, all other trace information is collected.

Collect diagnostics

The Collect procedure comprises selecting machines, starting the diagnostics collection, and then uploading the file containing the collection to Citrix or saving it locally.

1. Launch Scout. From the machine’s Start menu, select Citrix > Citrix Scout. On the opening page, click Collect.

2. Select machines. The Select machines page lists all the VDAs and Controllers in the site. You can filter the display by machine name. Select the check box next to each machine you want to collect diagnostics from, and then click Continue.

   To add other machines manually (such as StoreFront or Citrix Provisioning servers), see Add machines manually.

   Scout automatically launches verification tests on each selected machine, ensuring it meets the criteria listed in Verification tests. If verification fails, a message is posted in the Status column, and that machine’s check box is unselected. You can either:

   • Resolve the issue and then select the machine’s check box again. This triggers a retry of the verification tests.
   • Skip that machine (leave its check box unselected). Diagnostics won’t be collected from that machine.

   When the verification tests complete, click Continue.

3. Collect diagnostics. The summary lists all the machines from which diagnostics will be collected (the machines you selected that passed the verification tests). Click Start Collecting.

   During collection:

   • The Status column indicates the current collection state for a machine.
   • To stop an in-progress collection on a single machine, click Cancel in the Action column for that machine.
   • To stop all in-progress collections, click Stop Collection in the lower right corner of the page. Diagnostics from machines that have completed collection are kept. To resume the collection, click Retry in the Action column for each machine.
   • When the collection completes for all selected machines, the Stop Collection button in the lower right corner changes to Continue.
   • To collect diagnostics again, click Collect Again in that machine’s Action column. The newer collection overwrites the earlier.
   • If a collection fails, you can click Retry in the Action column. Only successful collections are uploaded or saved.
   • After the collection completes for all selected machines, don’t click Back. (If you click it, the collection is lost.)

   When the collection completes, click Continue.

4. Save or upload the collection. Choose whether to upload the file to Citrix, or save it on the local machine.

   If you choose to upload the file now, continue with Step 5.

   If you choose to save the file locally:

   • A Windows Save dialog box appears. Navigate to the desired location.
   • When the local save completes, the pathname of the file is displayed and linked. You can view the file. You can upload the file later to Citrix. See CTX136396.

   Click Done to return to the Scout opening page. You don’t need to complete any further steps in this procedure.

5. Authenticate for uploads and optionally specify a proxy. For details, see Upload authorization.

   • If you haven’t authenticated through Scout, continue with this step.
   • If you have authenticated through Scout, the stored authorization token is used by default. If this is what you want to do, select this option and click Continue. You aren’t prompted for credentials for this collection. Continue with Step 6.
   • If you authenticated previously, but want to reauthorize and get a new token, click Change/Reauthorize and continue with this step.

   Choose whether you want to use Citrix credentials or Citrix Cloud credentials to authenticate the upload. Click Continue. The credentials page appears only if you’re not using a stored token.

   On the credentials page:

   • If you want to use a proxy server for the file upload, click Configure proxy. You can instruct Scout to use the proxy settings configured for your browser’s internet properties. Or, you can enter the proxy server’s IP address and port number. Close the proxy dialog box.
   • For a Citrix Cloud account, click Generate token. Your default browser launches to a Citrix Cloud page where a token is displayed. Copy the token, and then paste it on the Scout page.
   • For a Citrix account, enter your credentials.

   When you’re done, click Continue.

6. Enter information about the upload.

   • The name field contains the default name for the file for the collected diagnostics. This suffices for most collections, although you can change the name. (If you delete the default name and leave the name field empty, the default name is used.)
   • Optionally, specify an 8-digit Citrix Support case number.
   • In the optional Description field, describe the issue and indicate when the issue occurred, if applicable.

   When you’re done, click Start Upload.

   During the upload, the lower left portion of the page approximates the percentage of the upload that has completed. To cancel an in-progress upload, click Stop Upload.

   When the upload completes, the URL of its location is displayed and linked. You can follow the link to the Citrix location to view the analysis of the upload, or you can copy the link.

   Click Done to return to the Scout opening page.

Trace and reproduce

The Trace and Reproduce procedure comprises selecting machines, starting a trace, reproducing issues, completing the diagnostics collection, and then uploading the file to Citrix, or saving it locally.

This procedure is similar to the standard Collect procedure. However, it allows you to start a trace on machines and then re-create issues on those machines. All diagnostics collections include AOT trace information. This procedure adds CDF traces to help troubleshooting.

1. Launch Scout. From the machine’s Start menu, select Citrix > Citrix Scout. On the opening page, click Trace & Reproduce.

2. Select machines. The Select machines page lists all the VDAs and Controllers in the site. You can filter the display by machine name. Select the check box next to each machine you want to collect traces and diagnostics from. Then click Continue.

   To add other machines manually (such as StoreFront or Citrix Provisioning servers), see Add machines manually.

   Scout automatically launches verification tests on each selected machine, making sure it meets the criteria listed in Verification tests. If verification fails for a machine, a message is posted in the Status column, and that machine’s check box is unselected. You can either:

   • Resolve the issue and then select the machine’s check box again. This triggers a retry of the verification tests.
   • Skip that machine (leave its check box unselected). Diagnostics and traces won’t be collected from that machine.

   When the verification tests complete, click Continue.

3. Start the trace. The summary lists all the machines from which traces will be collected. Click Start Tracing.

   On one or more of the selected machines, reproduce the issues you experienced. Trace collection continues while you’re doing that. When you’re done reproducing the issue, click Continue in Scout. That stops the trace.

   After you stop the trace, indicate whether you reproduced the issue during the trace.

4. Collect diagnostics from machines. Click Start Collecting. During collection:

   • The Status column indicates the current collection state for a machine.
   • To stop an in-progress collection on a single machine, click Cancel in the Action column for that machine.
   • To stop all in-progress collections, click Stop Collection in the lower right corner of the page. Diagnostics from machines that have completed collection are kept. To resume the collection, click Retry in the Action column for each machine.
   • When the collection completes for all selected machines, the Stop Collection button in the lower right corner changes to Continue.
   • To collect diagnostics again from a machine, click Collect Again in that machine’s Action column. The newer collection overwrites the earlier.
   • If a collection fails, you can click Retry in the Action column. Only successful collections are uploaded or saved.
   • After the collection completes for all selected machines, don’t click Back. (If you do, the collection is lost.)

   When the collection completes, click Continue.

5. Save or upload the collection. Choose whether to upload the file to Citrix or save it locally.

   If you choose to upload the file now, continue with Step 6.

   If you choose to save the file locally:

   • A Windows Save dialog box appears. Select the desired location.
   • When the local save completes, the pathname of the file is displayed and linked. You can view the file. Remember: You can upload the file later from Citrix; see CTX136396 for Citrix Insight Services.

   Click Done to return to the Scout opening page. You don’t need to complete any further steps in this procedure.

6. Authenticate for uploads and optionally specify proxy. Review Upload authorization for details of this process.

   • If you haven’t authenticated through Scout, continue with this step.
   • If you authenticated through Scout, the stored authorization token is used by default. If this what you want to do, choose this option and click Continue. You aren’t prompted for credentials for this collection. Continue with Step 7.
   • If you previously authenticated, but want to reauthorize and get a new token, click Change/Reauthorize and continue with this step.

   Choose whether you want to use Citrix credentials or Citrix Cloud credentials to authenticate the upload. Click Continue. The credentials page appears only if you’re not using a stored token.

   On the credentials page:

   • If you want to use a proxy server for the file upload, click Configure proxy. You can instruct Scout to use the proxy settings configured for your browser’s Internet Properties. Or, you can enter the proxy server’s IP address and port number. Close the proxy dialog box.
   • For a Citrix Cloud account, click Generate token. Your default browser launch to a Citrix Cloud page where a token is displayed. Copy the token, and then paste it on the Scout page.
   • For a Citrix account, enter your credentials.

   When you’re done, click Continue.

7. Provide information about the upload.

   Enter upload details:

   • The name field contains the default name for the file for the collected diagnostics. This suffices for most collections, although you can change the name. (If you delete the default name and leave the name field empty, the default name is used.)
   • Optionally, specify an 8-digit Citrix Support case number.
   • In the optional Description field, describe the issue and indicate when the issue occurred, if applicable.

   When you’re done, click Start Upload.

   During the upload, the lower left portion of the page approximates what percentage of the upload has completed. To cancel an in-progress upload, click Stop Upload.

   When the upload completes, the URL of its location is displayed and linked. You can follow the link to the Citrix location to view the analysis of the upload, or you can copy the link.

   Click Done to return to the Scout opening page.

Schedule collections

Note:

You can currently schedule collections, but not health checks.

The Schedule procedure comprises selecting machines and then setting or canceling the schedule. Scheduled collections are automatically uploaded to Citrix. (You can save scheduled collections locally using the PowerShell interface. See Citrix Call Home.)

1. Launch Scout. From the machine’s Start menu, select Citrix > Citrix Scout. On the opening page, click Schedule.

2. Select machines. All the VDAs and Controllers in the site are listed. You can filter the display by machine name.

   When you installed VDAs and Controllers using the graphical interface, if you set a Call Home schedule (see Citrix Call Home), Scout displays those settings, by default. You can use this version of Scout to start scheduled collections for the first time, or change a previously configured schedule.

   Although you enabled/disabled Call Home on a per-machine basis during component installation, a schedule configured in Scout affects all the machines you select.

   Select the check box next to each machine you want to collect diagnostics from, and then click Continue.

   To add other machines manually (such as StoreFront or Citrix Provisioning servers), see Add machines manually.

   Scout automatically launches verification tests on each of the selected machines, making sure it meets the criteria in Verification tests. If verification fails for a machine, a message is posted in the Status column, and that machine’s check box is unselected. You can either:

   • Resolve the issue and then select the machine’s check box again. This triggers a retry of the verification tests.
   • Skip that machine (leave its check box unselected). Diagnostics (or traces) won’t be collected from that machine.

   When the verification tests complete, click Continue.

   The summary page lists the machines to which schedules will be applied. Click Continue.

3. Set the schedule. Indicate when you want diagnostics to be collected. Remember: The schedule affects all selected machines.

   • To configure a weekly schedule for the selected machines, click Weekly. Choose the day of the week. Enter the time of day (24-hour clock) for the collection to begin.
   • To configure a daily schedule for the selected machines, click Daily. Enter the time of day (24-hour clock) for the collection to begin.
   • To cancel an existing schedule for the selected machines (and not replace it with another), click Off. This cancels any schedule that was previously configured for those machines.

   Click Continue.

4. Authenticate for uploads and optionally specify a proxy. Review Upload authorization for details of this process. Remember: You cannot use a stored token to authenticate when working with a Scout schedule.

   Choose whether you want to use Citrix credentials or Citrix Cloud credentials to authenticate the upload. Click Continue.

   On the credentials page:

   • If you want to use a proxy server for the file upload, click Configure proxy. You can instruct Scout to use the proxy settings configured for your browser’s Internet Properties. Or, you can enter the proxy server’s IP address and port number. Close the proxy dialog box.
   • For a Citrix Cloud account, click Generate token. Your default browser launches to a Citrix Cloud page where a token is displayed. Copy the token, and then paste it on the Scout page.
   • For a Citrix account, enter your credentials.

   When you’re done, click Continue.

   Review the configured schedule. Click Done to return to the Scout opening page.

   During a collection, each selected machine’s Windows application log contains entries about the collection and upload.

Run health checks

The Health Check procedure comprises selecting machines, starting the checking, and then reviewing the results report.

1. Launch Scout. From the machine’s Start menu, select Citrix > Citrix Scout. On the opening page, click Health Check.

2. Select machines. The Select machines page lists all the VDAs, Delivery Controllers, and License Servers discovered in the site. You can filter the display by machine name. Select the check box next to each machine you want to collect diagnostics from, and then click Continue.

   To add other component types (such as StoreFront servers), see Add machines manually. You cannot manually add Citrix Provisioning Servers or License Servers.

   Scout automatically launches verification tests on each selected machine, making sure it meets the criteria listed in Verification tests. If verification fails, a message is posted in the Status column, and that machine’s check box is cleared. You can either:

   • Resolve the issue and then select the machine’s check box again. This triggers a retry of the verification tests.
   • Skip that machine (leave its check box unselected). Health checks won’t be run for that machine.

   When the verification tests complete, click Continue.

3. Run the health checks on the selected machines. The summary lists the machines where the tests will run (the machines you selected that passed the verification tests). Click Start Checking.

   During and after checking:

   • The Status column indicates the current checking state for a machine.
   • To stop all in-progress checks, click Stop Checking in the lower right corner of the page. (You can’t cancel a single machine’s health check, only all selected machines. Information from machines that have completed the checks is kept.
   • When the checks complete for all selected machines, the Stop Checking button in the lower right corner changes to Done.
   • If a check fails, you can click Retry in the Action column.
   • If a check completes with no issues found, the Action column is empty.
   • If a check finds issues, click View Details to show the results.
   • After the check completes for all selected machines, don’t click Back. (If you do, the check results are lost.)
4. When the checks complete, click Done to return to the Scout opening page.

Heath check results

For report-generating Citrix checks, the reports contain:

• Time and date when the results report was generated
• Machines that were checked
• Conditions that the check looked for on the targeted machines
