I have a 3750 running 12.2.52 and all the gigabit interfaces that have
the GLC-GE-100FX SFP modules inserted never show any traffic stats
the 5min input and output rate is always zero, but everything works fine
and I can poll traffic via SNMP. So aren't the stats displayed on the interface.
GigabitEthernet1/0/7 is up, line protocol is up (connected)

Try this:
GigabitEthernet1/0/7
load-interval 30
This will allow you to view at 30 seconds interval. Take note that this can jack up the "cost" of your CPU.

No luck, even though the snmp shows utilization
nothing appears on the switch counters:

Try copy large files back and forth. If you really want per second statistics, try using 3rd party softwares like SolarWinds software.

That is not the issue, the interface is not showing any stats
regardless of how much data is sent over the line, the counters always register zero
