myNMS could/should report when a switch port serving a shared segment (determined by seeing multiple host MAC addresses on it) or an inter-switch link goes down. It could also have a configurable (according to site policy/practice) option to report on, say, router ports which are administratively up but operatinally down.
However NOCOL, Big Brother etc can also check other services on other devices (e.g. disk space on hosts) so if these functions are required a decision would have to be made whether to integrate such checking functions into myNMS (maybe using monitors from NOCOL/BB etc) or to make myNMS look like another monitor reporting into NOCOL/BB etc.
It might be possible to link into an existing cable-management system: at the author's site we were looking at the Caplum c-m system with an eye to this possibility.
dhcpd.hosts table showing which host MACs are allowed to use DHCP and what hostnames (and therefore IP addresses) they map into
dhcpd log file, from which we can extract which MACs are requesting addresses via DHCP on which subnets
check counting of hosts in pre-cooked hosts queries: numbers don't look right
flagging of status and counting of 'active' 'recent' 'unreg' etc needs to be improved - make status flags orthogonal i.e. can be 'unreg' AND 'recent' (or not so)
add count of nMACs (or colour text) to Switch:Port field
show last username + no of users as per dot1d listing
use HTML::Table throughout for table generation

change DB structure to store netgroups in same way as in NIS maps, but still sanity check them as at present.
