Dear Jamal,

Trace is actually designed to track packet. It records the detail of
packets which pass through predefined checkpoints in a network.

Monitor is usually use to collect statistic. It consists of snoop queue
which is attached in front of a queue. Every time a packet pass through
a snoop queue, it report to a monitor. Monitor is responsible for
collecting statistic.

Parts of your problem can be solved by using monitor (not by tracing).
However, I suggest you to modify C++ codes in order to collect that
statistics that you need. For example, you may add two
variables--start_time and end_time--to each node. At the end of
simulation, you can just find the difference between start_time and
end_time as connection time.

Good Luck,
Teerawat
