In our house, I dropped MRTG last year, and I'm using Cacti instead (http://www.cacti.net) It works the same as MRTG under the wire, but is much easier to configure and manage.
Let me guess, your network stats aren't correct on your GigE interfaces? Last time I looked, NetApp insists that SNMP v2c and v3 aren't mature enough for them to bother with. SNMP v1 only supports 32 bit variables, which overflow at about 115 Mbps. To get around that, NetApp provides high and low order 32 bit values for the network counters. You get to do the math yourself. Personally, I've found it much easier to just graph the switch port, which does support v2c. I've not seen any problems with the FE interfaces.

People,
I've used the filer-mrtg scripts from Now in the past, but I'd prefer to go down the SNMP route, as I suspect the network stats are not working well on the later releases of ONTAP ... Has anyone got some mrtg config files they can share with me?
I've tried using the search archive facility on the mathworks site but It's not much use as it does not sort in date order and you cannot see the whole of the subject!
Any advice welcome...
Cheers

This is sort of off-topic, but is there any known roadmap for an SNMP v2c or V3 implementation from NetApp? Just curious, since I'm also using cacti and am kind of sick of having to poll NetApp's "all interfaces" traffic OIDs.
