Top Level Protocols Message Count
The Top Level Protocols Message Count viewer Layout for Charts illustrates message data in a horizontal Bar element visualizer component that provides an at-a-glance view of the relative volume of the top-level messages from different source modules or protocols in a set of trace results. If you double-click any data bar element representing a message source in this Layout, the details for the top-level messages represented by that particular data bar element are rendered in a new instance of the Analysis Grid viewer for further analysis.
Using the Top Level Protocols Message Count Layout
This Layout can provide an immediate indication of which modules or protocols are the highest bandwidth consumers, based on the associated message count and/or the relative percent volume with respect to total volume of messages. As such, this Layout provides an at-a-glance view of the distribution of message volume per module in a set of trace results.
By double-clicking a bar element in this Layout, all messages in which the module is either a top-level message or part of message origins will display in a separate Analysis Grid viewer tab. Because all messages are displayed in a separate viewer tab as indicated, the message count in that viewer tab will differ from the Total message count specified in the Top Level Protocols Message Count viewer Layout. To see only the top-level messages in the new Analysis Grid viewer tab, you can apply a view Filter that isolates top-level messages by using the backslash symbol (“\”) described in Browsing Message Origins, as follows: “\<modulename>” — where <modulename> is a placeholder for the module or protocol of interest.
The Top Level Protocols Message Count Layout for the Chart viewer is intended to work with the ETW Layout for the Analysis Grid viewer and the ETW Guids and IDs Layout for the Grouping viewer, to create an integrated and interactive analysis environment. You will be able to correlate the data most effectively if you have these viewers and Layouts displayed. Note that these viewers and Layouts are configured in the ETW Analysis Profile and will display after you load data from an event trace log (*.etl) file, provided that you previously enabled this Profile on the Profiles tab of the Options dialog (accessible from the global Message Analyzer Tools menu).
As an example of interactively driving the display of messages, you can double-click any bar element in the Top Level Protocols Message Count Layout to display the messages in a new instance of the Analysis Grid viewer for focused analysis of the messages associated with a particular protocol or module. The ETW Guids and IDs Layout for the Grouping viewer also enables a greater interactive context with additional enhancements to the analysis process.
