TTR Events Panel

The TTR Event Panel displays a list of all TTR events associated with the selected transaction (TDR). Whenever the user selects a TDR in the TDR Panel, the TTR Event Panel is refreshed with the corresponding TTR events. The Event table has a number of columns:

The user can also click Toggle Ladder Diagram to view events in an Event Diagram.

• Time (the column is populated for payload events only. It contains the time when the message was received or sent)
• Event Type and Event Scope

• Transport Type (TCP or SCTP for payload events only)
• Connection Id (The name of the connection defined in DSR)
• Source Node (<Node name> - <IP address> for payload events; IP is translated and node name is displayed if there is a record in Local Node or Peer Node reference data at DSR for the given IP address)
• Source Port (TCP/STCP IP port number for payload events)
• Destination Node (<Node name> - <IP address> for payload events; IP is translated and node name is displayed if there is a record in Local Node or Peer Node reference data at DSR for the given IP address)
• Destination Port (TCP/STCP IP port number for payload events)
• Event Data (Event data from TTR event; Event Data for Answer payload events contains the result code from ResultCode AVP (code 268) or ExperimentalResultCode AVP (code 298) in the form of <Error Code> - <Error description>)
• Application (Diameter Application for payload events, empty for the rest)
• Command Code (Message command code in form of <Short name> - <Long name> for payload events)
• Message Priority (The numeric priority value from the priority services field in the diameter message)
• DSR-DSR (If the message transpired between two DSR nodes, then the column shows a YES value. If the message transpired between one DSR node and either a client (such as MME) or server (such as HSS), then the column shows a NO value. This value is required for N-IDIH to create a correct ladder diagram from the event list)
