NS_LOG export

[Mikael Priamuda]

Hi all. i would like to calculate convergence time in OLSR. And i need to know how does OLSR works using NS_LOG. But, i want to export the NS_LOG to be txt file. Can anyone help me?

Hi,

How to use NS_LOS is explained in the tutorial.

http://www.nsnam.org/docs/tutorial/html/tweaking.html

You can select to log only the OLSR component. 

Also, to print this output to a file, you just re-direct it (also mentioned in the tutorial, same section)

$ ./waf --run scratch/myfirst > log.out 2>&1

Having answered your questions, I would recommend NOT to use it to calculate convergence and generally do not use NS_LOG for analysis.

Study the documentation regarding tracing. It should be more efficient.

Thanks  Konstantinos for the answer. I will try your suggestion.

Is there a way to turn on NS_LOG for a specific node rather than logging information for every node?

[pdbarnes]

No. Logging is controlled at the source code file level, so typically you turn on logging for the protocol implemented in the file, independent I any nodes.

For a specific node use Tracing, as Konstantinos suggested.
