Monitoring server access ports:
There was some debate here at first regarding whether to do so or not.
All the pros of doing so could equally be applied to any resource anywhere in the environment if a department/group admin wished to do so.
Ultimately we took the stance of the network group will monitor the network hardware and the ports that are required for network connectivity. Server admins can worry about their NIC - we (network admin group) are not really concerned at that level of granularity. If there's an issue with a switchport it'll probably show up in the myriad of logical adapters (usually all) the server owner chooses for monitoring at the node level.
