Hello Buchan -
Have you made any progress at supporting the Cisco WLC with devmon? I have written a perl script to poll the required SNMP mibs, and combine the results, but I'm running into a wall trying to learn how Xymon expects to see "devmon-like data" submitted. I like how you are sending an entire repeater-mib worth of results, and I want to accomplish the same thing.
So - IF you have not been able to get devmon working for the above request, can you send me a pointer about how to send data like devmon? I'm hoping to use the "auto-rrd" tools that devmon/xymon seem to provide, rather than being forced into another NCV script.
Thanks for anything you can pass along.
