Using Nagios to monitor Cisco MDS 9509 switch?

Has anyone set up Nagios to monitor a Cisco MDS 9509 SAN switch?

Any tips/recomendations?

You'll need to use SNMP.

I haven't specifically used Nagios with this SAN Switch, but a good starting point is to look at the SNMP MIB files for the switch to see what stats/counters are supported. The MIBs define what counters are available. Nagios comes with it's own set of SNMP tools, but there also a few good windows based ones that you can use to browse the switch with the MIBs. http://www.wtcs.org/snmp4tpc/getif.htm. Also my favourite STG http://www.wtcs.org/informant/stg.htm which is good for verifying the counters work as expected.

Cisco MIB can be found here
http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml

The ones that I can see that are relevant to your switch.
CISCO-SVC-INTERFACE-MIB
CISCO-FICON-MIB
CISCO-FCSP-MIB
CISCO-FEATURE_CONTROL-MIB
CISCO-IVR-MIB
CISCO-FDMI-MIB
CISCO-SECURE_SHELL-MIB
CISCO-FC-ROUTE-MIB

Also rather than reiterate the finer points of inserting custom Cisco  counters into Nagios, here a link with some good detail. It's for Ethernet Switches, but the same principles apply to all cisco products with SNMP support.
