3.3.2.1 Ladder Diagram
The Ladder Diagram shows the TTR events in graphical form, providing an additional form of information shown in the TTR Event panel. Additionally, ProTrace will process and display Client Redirect events when received.
Figure 3-9 Ladder Diagram
The user can hover or click on a bubble of the ladder diagram which may show information about that particular bubble in the Diameter Full Decoding Panel.
The user can also click Toggle Event Table to view events in tabular form, which also allows for a selected row to appear in the Diameter Full Decoding Panel.
Table 3-2 defines how the TTR events are visualized in the ladder diagram:
