How to troubleshoot Complex Heavy Forwarder Flows

Path Finder

Hey Splunkers! i've inherited a Splunk deployment that utilizes multiple heavy forwarders that uses TCP Routing and several tcpout groups to send data to different locations. One of the issues i'm running into is most of the orginal team that deployed has left and there is little documentation. What is the best way to troubleshoot some of these flows? 


Right now i'm using tcpdump on the specific inputs/outputs ports and using that to built myself a visio diagram of the flows. Is this the best approach or are there other utilities I could use? I'm currently running 7.3.3
