[ndnSIM] Question about visualization and output

[李怿曈 Yitong LI]

I’ve configured them in the following steps.
1. ./waf configure -d optimized
2. ./waf
3. NS_LOG=ndn.Producer:ndn.Consumer ./waf --run grid3

Do you think there’s any mistake with them? As according to the documentation, it says using ./waf configure -d optimized can make ndnSIM in debug mode.

Thanks,
Caster

Question 1:
Yes, you don't really need to visualize to get any result. You can obtain metrics using these helper functions.

Question 2:
Seems like the ns-3 or ndnsim is compiled without the debug mode. Can you make sure everything is compiled with debugging enabled?

Hi all,

I’ve sent another question earlier, I just pasted it here with another relevant question regarding ndnSIM’s output.

1. What's the difference between running using "--visualize" or not. As the simulation can be started when activating visualization, what will happen if not using "—visualize”. I think that it should be possible to run the simulation and see the output report even without “—visualize” option?

2. As there’s problem with kiwi, I tried using ndnSim without “—visualize” and added NS_LOG to see outputs on cmd. However, it gave me nothing when using “NS_LOG=ndn.Producer:ndn.Consumer”, I’ve added testing print info in my program, it seems everything is fine. May I ask what’s the potential reason for this? I’ve attached log and source file below. My problem is that I can’t see the log outputs now.
