anything is possible with a custom SQL alert on an interface
something like this
where interfaceid in (SELECTinterfaceid
FROM (SELECTSum(in_totalbytes)TB,
interfaceid
FROM [dbo].[interfacetraffic_detail]
WHERE in_totalbytesISNOTNULL
GROUP BYinterfaceid
HAVING(Sum(in_totalbytes)>2e12))X )
2e12 ~= 2TB chnage this to 190e9 if to mean 190Gigabytes.
