is there a better place to post this? I still cant figure this out

i am working with tshark, tcpdump, and ssldump but im not sure if i can get it to work right

I have a server with a bitcoin wallet and bitcoin.conf for me to use. There are automated json rpc requests going through it, and id like to know if there is a way to log the requests made to it somehow. The server runs on linux, and I had someone set it up for me, so I'm a bit rusty on figuring this out. I dont see anywhere the .conf is able to keep history or logs. Maybe there is a way to log anything being sent to the server, surely that can be done right? I already searched through the var/logs and searched for strings but didnt see anything.

EDIT: oh and also the requesting json cant be edited at the moment, id like to see if i can do it server side. also -debug=rpc doesnt spit out exactly the message recieved
