Conversation map

The DNA Conversation Map provides a top-level view of the nodes and conversations associated with a captured task activity.

To open a Conversation Map:

  • Double-click a task in Task Hierarchy.

  • Select a task in Task Hierarchy and then select View  ► Conversation Map from the main menu bar.

  • Right-click a task in Task Hierarchy and select Conversation Map from the pop-up menu.

  • Select a task in Task Hierarchy and then press [Ctrl-M] .

  • Select a task in Task Hierarchy and then click Conversation map icon on the toolbar.

  • Save a capture or import a trace file. The Conversation Map is the default view in DNA. When you save a capture or import a trace file, it is automatically displayed in a conversation map.

For an example from the sample database, right-click the task ShoppingCartInStock and select Conversation Map.

The square node icon indicates that WCA1234B is the client node. The only other node in the conversation, CITRIXSERVERADV, is the server. There were 23,886 bytes sent from client to server, 2,888 bytes sent from server to client, and one error detected. To change these measurements to Payload Bytes, Frames, or App. Turns (application turns), right-click the map and select another measurement. To investigate the error, select View  ► Error Analysis or click Error analysis icon on the toolbar.

The task name and display metric are shown in the title. Each line in the ring represents a conversation between the nodes it connects. Each node is named or its address is provided depending upon whether DNA can resolve the address to a name. If the task is unmerged, the square representing the client node is colored yellow and often appears at the bottom of the ellipse in an unadjusted task. It may be placed on the left side in a two node unadjusted trace, or wherever you have specified, if you have saved the node positions.

Note

DNA tries to resolve IP addresses to their domain names. This can take a significant amount of time. Initially, you may see a conversation map with the IP addresses shown and later see that the same map updated to show the domain names.
