We use What's Up Gold to monitor our Cisco devices.  On the area where it finds the Interfaces, it used to just list the two that were in use (i'm sure it is the inside and outside, Eth0/0 and 0/1).  This was when the IOS was version 7.x.   Now we have some 8.x IOS out there, and What's Up Gold discovers 14 Interfaces and I have no idea what they are.  Does anyone know why this might be happening?

Not sure why it shows 14 interfaces unless you've defined additional VLANs... it is showing all interfaces rather than those that are in use. The 5505 has a minimum of eight interfaces, Ethernet 0/0 through 0/7 and generally two or three VLANs (for inside, outside, and possibly DMZ).

Yes, there are 8 physical interfaces and then 2 vlans, one for inside and one for outside.

I'm not sure why this changed, but for simplicity I just let them all be discovered and then I delete all of them other than the inside and outside interface, which is what we used to monitor.

Wasn't able to come up with a good explanation of why this changed with the newer IOS.  So my solution is acutally more of a workaround so to speak.
