The autodetection is nice, but think there should be a failsafe to
override the autodetection by having the option to hardcode. I thouhgt
hardcoding with the bbtag like "DEVMON:cisco-2920".

I have a lot of templates to make now ;) Anyone have suggestions on the
best/eaiest method ?  I would assume I need to grab the SNMP MIB from
the device vendor, and then use that info to make the template.
Currently I have been reading the raw text MIB, and it barely makes
sense ;)  Any tool you know of to assist ?

Again, thanks for your hard work on this. Happy to help however I can.
