Does anyone know a nice easy way to tell where network traffic is coming from? Something like nfssat -l where you can see that x% of your traffic comes from xxx.xxx.xxx.xxx or something like that? I have tons and tons of writes happending on my 740, which is killing the CPU. The problem is it just started the other day and it is killing the overall performance of the filer. nfsstat -l shows me the number of NFS ops, and none of them seem out of line at all.
Ideas?

Try MRTG. Do a google search. It's an SNMP tool that allows you to script "things" reported by SNMP.
At the minimum, run it against the filer and the switch for the office, if it's SNMP'able, and you should be able to see the port it's coming from..at a minimum.
But also, using stats on the filter to track down the file set is useful. I haven't had to do this in awhile, so I can't help you there.

Hi,
Touching on the subject of MRTG, I suggest using it's successor - cricket:

I'll second that comment -- we are using cricket to help manage 28 filers in 3 buildings in 2 states. About 15TB.

We're using FILER-MRTG as distributed by NetApp. Could anyone donate some functional (and hopefully documented) cricket configurations for filers?

If you try the URL "http://sourceforge.net/projects/cricket/", you will get to the project webpage that includes access to a "patches" database. The patches database houses a number of configuration files for various systems. (including NetApp)
