TCP Rate and Diagnosis

The TCP Rate and Diagnoses view Layout for Charts enables you to obtain a focused view of specific TCP data from a set of trace results that tells you the ratio of Diagnoses messages to all messages in each IP conversation in which Diagnoses errors occurred. This Layout uses a Table grid visualizer component that is driven by a data formula that automatically calculates a Rate value that exposes this message ratio. This Layout also has a TCP Viewpoint applied in the background, which isolates TCP messages to create a focused analysis context.

Using the TCP Rate and Diagnoses Layout

Because Message Analyzer automatically calculates the indicated Rate value, you can quickly narrow down the IP conversations where the highest Rate values exist, which in turn can provide a focus point for further investigation of TCP issues. For example, if you have a Rate value of .50, this means that half of the messages in a particular IP conversation contain underlying TCP Diagnoses messages. A Rate at this level could be significant, especially if the conversation also contains a high message count. To proceed with analysis, you might double-click the table grid row containing the Rate of interest to drive the display of conversation messages into a new instance of the Analysis Grid viewer for further analysis of the TCP Diagnoses messages and other message Details. From the Analysis Grid viewer, you can click a Diagnoses message icon in the DiagnosisTypes column to display the inline details for the Diagnoses message. In addition, given that the Diagnostics Tool Window data is driven by the content of the current in-focus data viewer, you can conveniently review the details of all Diagnoses messages in the IP conversation with which you are working from this Tool Window.


If the Diagnostics Tool Window is not displayed, you will need to enable it on the Features tab of the Options dialog in the global Message Analyzer Tools menu, and then restart Message Analyzer. Thereafter, you will need to select the Diagnostics window from the Windows submenu of the global Tools menu to launch it.
