Protocol Dashboard

  • 發行項

The Protocol Dashboard is a Chart-style data viewer that enables you to obtain a quick assessment of trace performance from graphic visualizer components that provide top-level summary information. It exists in the Dashboards category of your local Charts asset collection Library, which is accessible from the locations described in Chart Viewer Layouts. A description of the visualizer components that are contained in the Protocol Dashboard follows.

Using the Protocol Dashboard

The Protocol Dashboard contains the following visualizer components:

  • Top Level Protocol Summary grid — consists of a table that provides a summary of the top-level messages retrieved by various modules in a trace, along with the number of top-level messages received from each module.

Note

If you double-click a table row, 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 top-level message count specified in the Top Level Protocol Summary table. 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.

  • Top Level Protocol Summary bar Chart — this visualizer component illustrates message data in a linear graphic format that provides an at-a-glance view of the relative volume of the top-level messages received from different source modules over the trace timeline. If you double-click any data bar representing a message source in this Chart, the details for the top-level messages represented by that particular data bar are rendered in a separate Analysis Grid viewer tab for further analysis.

Note

If you double-click a bar in the bar Chart visualizer component, you will see the same message count disparity as described in the previous note. Similar to the table grid, you can see the top-level messages by applying a view Filter with the backslash symbol (“\”), as previously indicated.

  • Top Level Protocol Summary pie Chart — similar to the Top Level Protocol Summary bar Chart, this visualizer component also illustrates the relative volume of top-level messages received from different source modules; however, the data is presented in a pie chart configuration instead. In this Chart, message volume for source modules is delineated as a percentage of the whole so you can quickly obtain the top protocol usage-percentage in the trace. You can also double-click any source module in the Top Level Protocol Summary pie Chart to present the associated top-level message details in the Message Analyzer Analysis Grid viewer.

Note

Both the bar and pie Chart visualizer components can provide an at-a-glance indication of the top bandwidth consumers in a trace.

  • Top Level Protocols Over Time timeline Chart — this visualizer component provides a graphic, X-Y axis formatted chart. This component depicts message count as X-axis module lines that indicate the number of messages that were captured for a particular module across the entire trace timeline, with individual message nodes indicating the points in time when messages were captured. You can view the message count at any node for any module by hovering over one with your mouse and also in the legend to the right of the graphic viewer surface. In addition, the Y-axis is calibrated to provide an indication of relative message count for any node.

    In addition, if you double-click a node or a module line, all the top-level messages and origins associated with that module will display in a separate Analysis Grid viewer tab for further analysis. You can also focus on the messages from a particular module by selecting them in a legend to the right of the timeline, and clearing selections of the message types you do not want to display. Lastly, this visualizer component enables you to adjust selectable time-window slider controls so that you can do the following:

    • Visually assess the times at which protocol communications occurred within the time range of a trace.

    • Use manual adjustments to drill down into specific time slots for a more granular view of the message activity that transpired there.

    • Use Zoom presets to automatically create time windows that enable you to drill down into message activity in various time slots, starting from the beginning of a trace.

      These preset values create time windows that are 100 ms, 1s, or 5s in length. After you specify one of these presets, you can return to the full trace time boundaries by clicking the All preset, or you can manually expand the trace boundaries with the time window slider controls.

Tip

If you apply a view Filter or a Time Filter to the Protocol Dashboard viewer in a particular session, messages will be appropriately filtered in this viewer only, while the message data in any other viewer opened in the same session remains unaffected.
