I've searched the forum and library for clues to this question, but didn't see anything specifically addressing it:
I maintain several N-R instances with many flows each. With something like nethogs, I can see network traffic volume to and from a N-R instance in general , but not to see which flows / nodes / etc are sending or receiving that traffic.
Is there a way for me to see this Tx / Rx information in a more fine-grained way, broken down at the flow or node level?
Thanks and happy New Year,
Viewed from the outside, there is little information that relates traffic to a specific node though if you are monitoring msg's via MQTT, websocket or another network transmission method, then you will have the
HTTP traffic from one of the UI's (the Editor for administration, or /ui for Dashboard, etc) again will not be easily relatable though in the Editor, I think that most nodes will have an ID that should be relatable.
Probably the easiest (and it isn't that easy - at least for a non-pro developer like me) method is to start up Node-RED with node.js's
--inspect parameter. Then you can use something like VScode or one of the Chromium-based browsers (Vivaldi is good for example) to monitor the code as it executes.
