How to check the socket communication log

[SAPSupport]

Hi Team,

Check the connection status between SAP and external devices at the socket communication handshake level.
Could you tell me how to check the logs (transactions)?
For example:
socket->bind()->listen()->connect()->accept()
at the log level.
If available, the transaction code and the log name to be referenced
I would appreciate it if you could tell me.

In the SAP system, communication with external devices and systems often occurs through various interfaces like IDoc, RFC, or web services. However, checking the socket level communication details directly from the SAP system is not straightforward. SAP typically abstracts these lower-level details.

If you suspect that there are issues at the socket level, you may need to use network monitoring or diagnostic tools outside of SAP. You can use packet capturing tools like Wireshark or tcpdump, or network monitoring software to inspect the details of network packets at the socket level.
