running rmon against dockerised rrcpd, ads, adh - which NIC and rrcpd ports should I use?

hi I am trying to run rmon to understand some packet congestion we see on TREP network. All 4 infra processes are running in docker using "host" networking. I have extracted the rrcp ports from the process config files which gave me :

-r is from *RRCP*ports : 0x4e20 0x4e21 0x4e30 0x4e31

-R is from *sink*RRCP*recvMultAddress

-W is from *source*RRCP*recvMultAddress

./rmon -S -i bond0 -p 1 -R *.*.*.2 -W *.*.*.3 -k 4 -r 20000 -w 20001 2> err.log

this gives me the following output:

I have a few questions:

Does this output look reasonable?
However if I run using the other two rrcp ports 20016/20017 the RRMP6 section at the bottom disappears - why is that?
Can you advise if I am running the right rmon parameters to investigate congestion on the TREP network?

Also can you point out which stats are important regarding congestion messages (which lead to dropped ticks)?

Do I need to run rmon in each of the 4 TREP containers to fully analyse the TREP infrastructure (ie rrcpd, rrcpd, ads, adh)

How do I check which NIC TREP is using for each container?

any other comments? Sorry the question is a bit nebulous, but I couldnt find much documentation on this.
