NetApp and cifs - where is the traffic going

Usually my posts are MySQL related though sometimes I will add something that I find that may not be related to MySQL....  like this. Sorry guys at http://planet.mysql.com :)

Here is a cool little NetApp feature to see where all the lovely windows CIFS traffic is going.

The command is 'cifs top' and it needs to have stats capture enabled on the NetApp for it to work. Here it is in action.

nas01b> cifs top

I hope this is useful in debugging where the lovely NetApp cifs traffic is going :)
