Hello Farouk,
the best way to achieve what you explained depends on your intention.
One way would be to start the daemon in debug mode with a level of at least 70 and watch out for "MSG_DATA_SEGMENT received". This indicates an ongoing transfer. It does not tell you if the bundle will be accepted by the daemon or if the data is being received by a TCP-CL or the API. If you plan to measure performance this way, you'll have to consider that debug output will slow down the overall performance of the daemon.
If you plan to implement some feature within the daemon, you could integrate some indicator within the function:
void BundleCore::validate(const dtn::data::PrimaryBlock &p)
This function is called on every bundle processed by the daemon as soon as the primary bundle header is available. Be aware that this is not only the case if a bundle is received by the API or a convergence-layer. This function is also called if a bundle is restored from a file within the storage.
I hope this information is useful for you.
Kind regards, Johannes

@Sebastian : When a bundle is received, a BundleReceivedEvent is raised by the TCPConnection (if the two nodes communicate with TCP). Farouk wants to know when a bundle is being received. @Farouk : what do you want to do with this information ?
