2.5 An Example of Trace Output
This section presents an example of trace output.
Although the exact contents of trace output are protocol-specific, there are some
general features common to all kinds of trace output.
One common feature is the trace output header, which shows:
• When the trace was started
• When the trace was analyzed
All trace output is divided into columns containing the following types of
information for each trace record:
• The time at which the trace record was generated.
• The event code of the event that caused the trace record to be generated.
• The size of the protocol message associated with the trace record.
• The contents of the protocol message associated with the trace record.
The following example consists of trace records collected from a tracepoint at a
ROUTING CIRCUIT entity. These trace records represent the PDUs that are
transmitted and received on that circuit by the DNA Routing module.
