Hi Mark,
Thank you very much for the information.
About the documentation, I was unable to find a specific command in
collectl documentation on sockets [1]. So I tried googling and found few
inputs [2] [3] which suggested me different mechanism which did not work
perfectly.
collectl -Aserver:port does what I need.
Thank you for the input on this handy and lightweight tool for monitoring :)
