How to find out what kind of traffic an application creates in a communication channel?

Question

Network administration

Good afternoon.
There is a server where the application runs on SQL and there are remote branches that work with this application.
What means can be used to evaluate the load on the communication channel between the branch and the server?
I would like to know what kind of traffic this application creates, so that in the future it would be possible to calculate the load on the communication channel when opening new branches.

Well, figs what you have there for iron, etc. and what he can do from monitoring.
But in a simple and high-quality way - you take any monitoring system (zabbix, nagios, prometheus, etc) and set it on interfaces, you get beautiful graphs with a daily load on interfaces, and accordingly, you immediately understand the amount of traffic.
PS At the same time monitoring will appear :)
