DNA provides several utility applications to help you analyze your networked applications.

Simple capture

The Simple capture application is a standalone Windows utility provided with DNA. Use it to capture traces on Windows computers that do not have the DNA console or its remote agents installed.

This utility enables you to perform the captures without console interaction, and is valuable for cases in which security policies, firewalls, or simple lack of connectivity prevents the DNA console from communicating directly with the end-user PC.

The utility’s captured traces are always encrypted so they can safely be emailed or otherwise sent to computers that have DNA installed.

The executable file (AVSimpleCapture.exe) and associated files are in a ZIP file named AVCaptureUtility.zip available in the console installation directory.

As the name suggests, this application is simple and easy to use right out of the box, but if necessary, you can set special capture options by editing captureconfig.ini with a text editor.

The options give you the ability to:

  • Run in interactive or silent mode. The default is to run in interactive mode.

  • Duration to run in silent mode. The default is 20 seconds.

  • Select the Network Interface Card (NIC) to capture on.

  • Select the capture filter file name.

  • Set the capture buffer size. The default is 16384. The maximum supported capture size is 204800 K (200 MB).

  • Select buffer overwrite. The default is to not overwrite.

  • Enable Active Latency Detection. It is enabled by default.

  • Set ALD port. The default ALD port is 2408. You can specify another port number.

  • Set ALD filter. The default is to filter out ALD. When specified, the ALD ping packets are not filtered out of the captured trace.

  • Set ALD resolver. The default is to not resolve. If specified, ALD nodes are resolved to DNS or NETBIOS names.

  • Select output trace file name

  • Capture in non-promiscuous mode or promiscuous mode. Promiscuous mode is the default.

  • Enable/disable Browser Data Collection. Enabled is the default.

Expert guide editor

The Expert guide editor included in the distribution allows you to modify the standard Expert guide or to create an entirely new guide.

Basic Expert guide editor concepts:

  • A guide is a document that consists of pages links and text.

  • Links are hyperlinks that can either jump to actions (active DNA commands) or to other pages in the guide.

  • Text explains the concepts involved and the function of the links.

Important:

If you are not clear on what an Expert guide does, open a test database and try the default Expert guide. An Expert guide can take real actions such as deleting some or all of the data from the current database. Be careful not to use live data when you experiment.

The Expert guide editor utility, as the editor, provides you the means to create and connect each of these elements to construct or modify an Expert guide.

For further information, open the Expert guide editor and refer to its help system.

Duplicate packet remover utility

Duplicate packet remover works with the Error analysis view. It looks for tasks with errors of type Network: duplicate frame and removes the duplicate frames.

Assigning the error type Network: duplicate frame a category of Warning, Info, or None does not affect this operation.

Perform the following steps to use Duplicate packet remover:

  1. Select a task in Task hierarchy and then select Tools ► Power tools ► Duplicate packet remover.

  2. The Duplicate packet remover window opens with the task's duplicate frames listed in a table.

    Indicate whether you want to remove all duplicate packets in the task or to specify certain packets to remove.

  3. If you accepted the default of removing all duplicate packets in the task, click Remove duplicate packets.

  4. If you indicated that you want to remove specific packets, edit the list to make sure that only the frames you want to delete are selected (you can sort on any column to help you find frames) and then click Remove duplicate packets.

  5. The duplicate frames are removed, the task is re-profiled, and Duplicate packet remover closes, returning you to DNA.
