How to enable AppDNA verbose logging
Note: For more information on all types of logging in AppDNA, see CTX219766.
If you are having issues installing Citrix AppDNA, these steps show you how to enable the collection of detailed installation log files on the AppDNA server.
Caution: Editing the registry incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.
To enable verbose logging on the AppDNA server, complete the following procedure:
When AppDNA detects that this registry value has been set, it writes the verbose logs to %temp%\AppDNAVerboseLog.log.
Note that for the server processes this will be the temp directory for the identity that the AppDNAAppPool is running under in IIS. By default this will be the build in "ApplicationPoolIdentity" and the temporary directory will be C:\windows\temp.
Logs are captured separately for the client and server processes (unless they are running as the same user).
Use a text editor to read the contents of the AppDNAVerboseLog.log file.
To disable the verbose logging, change the VerboseLogging registry value to 0.
A similar process can be followed to turn on verbose logging for the Citrix AppDNA Service, QueueProcessor. To enable verbose logging for the QueueProcessor service, follow steps 1-4 above. In step 5, find or create the registry value QueueProcessorVerboseLogging. Messages are written to the windows event log (rather than a file) in:
EventViewer > Application and Service Logs > AppDNA > Source = AppDNA Service
This error might mean that the password that the AppDNA web site uses to connect to the AppDNA database has expired or has been changed. To correct this issue, see Web site.
This error sometimes occurs because one of the AppDNA services or another service that AppDNA relies on is not running.
Check the IIS services
To do this, in the Actions panel on the right side of the window, under Manage Server, click Start. The Start link is disabled if the server is running.
To do this, expand the tree on the left side of the IIS Manager window and click Application Pools. Click AppDNAAppPool in the middle panel and then click Start in the panel on the right. The Start link is disabled if the AppDNAAppPool is running.
To do this, expand the Sites node in the tree view on the left side of the IIS Manager window and click the AppDNA web site (by default, this is called AppDNA). Then click Start in the panel on the right. The Start link is disabled if the AppDNA web site is running.
If you restarted any of the IIS services, try logging on to AppDNA again. Otherwise, check that the SQL Server Instance service is running and if necessary start it, as follows:
This error occurs if Internet Explorer is configured to use a proxy server for your LAN. You can work around this issue as follows:
This section provides information to help you troubleshoot licensing problems, including those that cause the AppDNA banner to go red. When this happens, look at the explanatory message in the Module license summary section of the Dashboard. This generally makes it clear whether the problem is caused by AppDNA not being able to contact the AppDNA license server or by a problem with the actual licensing of the database itself. Information follows for each of these root causes under separate headings.
You can continue to use AppDNA with the licensing problem and the red banner. However, the functionality is very restricted - you can import applications, but most other features are blocked. Once the licensing issue is resolved, the blocked features will be available again.
If AppDNA displays a message that it cannot contact the license server, it may mean that the AppDNA license server is not running. You can check this and if necessary restart it as follows:
AppDNA licenses are tied to both the database and the machine on which the AppDNA license server is running when the license is activated. Problems can arise when the link between the license in the database and the license server location is broken – for example, because you have moved your AppDNA server from one machine to another, or you have started, but not completed, the two-stage procedure for transferring a license.
For more information, refer to Transfer Licenses.
By default the AppDNA license server uses port 8079. If that port is not available, change it as follows.
The default location is C:\Program Files[ (x86)]\Citrix\AppDNA\License Server.
<channel ref="tcp" port="8079" bindTo="0.0.0.0">
This error message can occur during analysis or any type of import. It is generally caused by the database not having enough disk space to expand.
To do this, in the tree view on the left side, open thefolder. View the recent logs and look for text that says that there is not enough space on disk. If disk space is the issue, follow the steps below.
In the tree view on the left side, open the Databases folder. Then right-click the AppDNA database and from the shortcut menu, choose Properties. This opens the Database Properties dialog box. Click Files in the side bar and ensure that both the data file and the log file are configured to grow in small chunks (for example, by 10%) and that there is no maximum size set.
In the Database Properties dialog box, click Options in the side bar, and ensure that the Recovery model is set to Simple.
When you import .sft or .appv packages, AppDNA automatically unpacks their contents into an intermediate folder, preserving the original directory structure. This fails if the total number of characters in the resulting file path exceeds the Windows limit (typically 256 characters). When this happens, the import log file contains the text: create_deep_dir.
By default, AppDNA unpacks .sft and .appv files into the temporary folder specified in File settings. However, you can specify a separate intermediate folder for .sft and .appv files in the SFT intermediate folder box in Import and analyze settings.
To resolve this issue, set a very short file path for the SFT intermediate folder. AppDNA does not automatically clear this folder. If necessary, you can delete the unpacked files manually after the import has finished.
This occasionally occurs with applications that have been imported through Install Capture or Self-Provisioning when the installation fails but the installer does not follow the convention of returning zero for success and a non-zero value for a failure. When this happens, by default AppDNA assumes that the capture has succeeded, imports the DNA captured, and marks the import as successful – although in fact no real application DNA was captured at all. In this situation, the captured DNA consists of any minor changes that the failed attempt to install the application made to the underlying operating system.
If you ran the capture using auto-clicker, the installation may have failed because it was waiting for user input. Therefore, run the capture again without auto-clicker. This may enable the installation, and therefore the capture, to complete successfully.
Alternatively, if you know that an installer does not follow the convention of returning a zero exit code on success, you can specify the success exit code in the execution profile for that application. See Edit an execution profile for information about how to do this.
When the import of an OS image fails with a "404: File Not Found" error, it generally means that limits on the size of the maximum content length has been exceeded in IIS. To increase the maximum allowed content length, refer to the instructions under "Optimize IIS" in Optimize AppDNA.
This problem sometimes occurs when the number of records per page has inadvertently been set to a very large value. If the page is so slow that it is unusable, navigate away from the report view and change the number of records per page, as follows.
To change the number of records per page in the web client:
Where n is the required default page size, as shown in the following example. For clarity, this URL is shown on multiple lines. In practice the URL must be entered as one unbroken string.

This problem has been encountered when first viewing reports after installing AppDNA on Windows 8. The problem was caused by an incomplete configuration of Internet Information Services (IIS).
To resolve this problem:
The main Effort Calculator screen is not readable when the "Make it easier to read what's on your screen" display option in Control Panel is used to increase the size of the text and other items on your screen by, for example, 125%. This option is sometimes on by default on Windows 8.
When this option is in use, Effort Calculator increases the size of the text. This causes the text to be truncated or to run over other items making them unreadable. Some other reports are affected in a similar way.
The solution is to reset the display size to the 100% setting in.
If you attempt to perform a PDF export after installing Adobe Reader but before you have actually run Adobe Reader or opened a PDF file, the PDF export fails with an error ("This app can't be activated when UAC is disabled"). This is because the AppDNA PDF export does not work until you have accepted the Adobe Reader license agreement.
To resolve this issue, open a PDF file on the machine on which you are running AppDNA and accept the Adobe Reader license agreement.
When a report has a large number of algorithm groups, the columns in the Report Data section of the PDF exports may overlap and become unreadable. To resolve this issue, clear the Show counts in PDF exports check box in Reporting settings and then run the PDF export again.
