I wrote something like this in Perl a few years back and it's really
helpful, for switches and routers if Zenoss could poll the devices, get
their forwarding database (mac addys and ports) and their arp tables.
Then allow one to see what devices are attached to a particular port on
a network device.
It was tricky with some layer 2 only devices in that you would have to
look at the macs in their table and try and match it up to arp that may
exist in another layer 3 device's table.
The last thing I did with it was to get not only the ip address and the
resolved hostname of a host attached to a piece of network equipment but
tie into LDAP to get additional info about that host (ie who it belongs
too).
Basicly it allowed me to click on a port and see everything attached to
it down to the user info and also the ability to search on a user, host
or an ip address and to find it's port on whichever network device it
resides. As an added bonus to it, I was able to keep track of static IP
address allocation from the polled arps also.
I doubt tieing into LDAP would be something that could be feaseable in
Zenoss since everyone uses different schemes, other than that part I'd
love to see some of the above functionality in Zenoss.
