Particular VLAN issue connecting Internet

We have a setup with a couple of VLAN's. Recently users on a particular VLAN started complaining that internet connection only drops for about 10 to 20 minutes and will resume. In a day it might happen a couple of time. I thought at first that it is to do with our internet link however users on a different VLAN works fine without and drops

 

From CLI is there a way to monitor to see any thing that is unusual and pinpoint the source (mac-address or port etc)

 

If I have to run wireshark any particular thing that I need to look for ? What I have done so far was removed an unmanaged switch (planet) hooked up to one of the HP switch directly connected to the affected VLAN. Also I notice a new MFP installed and I have disabled all the network services that is not needed

 

Any help rendered will be very much appreciated
