Is there any way, we can monitor different subflows, interface used by them and subflow specific congestion window, RTT without dumping PCAP

you can use the linux utility called ss or inject some eBFP code that will push this in userspace.

Also, if you have the source of your application, you can use socket-option MPTCP_INFO: https://multipath-tcp.org/pmwiki.php/Users/ConfigureMPTCP
