Some people asked me at NETWAYS Nagios Konferenz if my check_netappfiler plugin is dead.
No, it's not!
With ONTAP 7.3 NetApp added support for SNMP v2c and v3! W00t!
Get the plugin (and some minimal documenation - you have been warned! ;) on http://people.teamix.net/~svelt/check_netappfiler/!
And PLEASE send me feedback (yes, "it's wonderful!" IS feedback ;) if you're using it!
