AnimationInterface.EnablePacketMetaData not working

[subhrendu chattopadhyay]

Hi All,

I am having problem in utilizing AnimationInterface.EnablePacketMetaData. When I am using this method with true argument it is showing the following message

"assert failed. cond="!m_metadataSkipped", msg="Error: attempting to enable the packet metadata subsystem too late in the simulation, which is not allowed."

However putting this function in the beginning of the run method results in build failure. I need to trace the packet meta data in animation.

If somebody can tell me how to do this I will be in debt to him. Please help me.

Thanks you.

Subhrendu.

That's the correct way I think to implement EnablePacketMetadata.
   
    Simulator::Stop(Seconds(10.0));
    AnimationInterface anim ("example.xml");
    anim.AnimationInterface::EnablePacketMetadata(true);
    Simulator::Run();
    Simulator::Destroy();

Hi,
Thanks for your help. Following is the code I have implemented. But it is giving an error which I have mentioned in my previous post. Please let me know what's wrong in the code.

int MeshTest::Run (){
  std::string animFile = "reports/mesh_animation.xml" ;  // Name of file for animation output
  std::string routeTrackFile = "reports/mesh_track_route.xml" ;  // Name of file for animation output
  CreateNodes ();
  InstallInternetStack ();
  InstallApplication ();
  //Simulator::Schedule (Seconds (m_totalTime), &MeshTest::Report, this);
  Simulator::Stop (Seconds (m_totalTime));
  // Create the animation object and configure for specified output
  AnimationInterface anim (animFile);
  //anim.EnableIpv4RouteTracking(routeTrackFile,Seconds(0.0),Seconds())
  //anim.EnableIpv4RouteTracking(routeTrackFile,Seconds(0.0),Seconds(m_totalTime),Seconds(5));
  anim.AnimationInterface::EnablePacketMetadata(true);
  Simulator::Run ();
  std::cout << "Animation Trace file created:" << animFile.c_str ()<< std::endl;
  Simulator::Destroy ();
  return 0;

Yes, that is an old issue with the mesh-module. You will most likely see the same issue, when you enable Ascii tracing with packet printing.

There is no fix for this yet

Hi John,

Thanks for your help anyway. I hope this method works in rest of the system other than mesh. Am I correct?

Use patch bug1363.patch ,it may work... but you should remove or comment some assert statements which u will get as errors
