High Receive Utilization on my Cisco 3560 V2

I use a Cisco 3560 V2 switch that is managed.  This switch connects our entire company network together (16 sites).  I monitored all our of network devices using Solar Winds.  I noticed that I got an alert that my switch had a high received utilization of 98%.  This started this morning at 6:21 am.  The average is around 53%.  I have logged into my switch, but I can't seem to figure out what is putting out this traffic.  This port is the port that connects my location to the network - approximately 50 computers and voip phones.  How do I find out where this issue is coming from?  SolarWinds shows me the port on the switch, but since so many devices are connect to that port via 3 other switches, I have no idea how to find this out.  Any suggestions?

use a traffic sniffer. btw i though solarthing had a builtin feature to show you which ip and/or port is cluttering the most bandwidth... check into that first

The problem was with a process running on my cloud backup that had hung up and causing the high utilization on my switch.  I killed the job and everything worked fine.

i honestly do not care about points but this is your question

How do I find out where this issue is coming from?  SolarWinds shows me the port on the switch, but since so many devices are connect to that port via 3 other switches, I have no idea how to find this out.  Any suggestions?
