Hi Bill, setting the log level on the Agent category is sufficient for having the log output of the simulation agent. That you do not see any log output is quite unusual and I do not have any idea how this could happen.
If you use the start parameters as follows:
udp:0.0.0.0/4700
You should get the following log output (at the end):
