Most servers these days have some sort of out of band management capability. HP has iLo, Dell has DRAC and IBM has IMM.
Most of these out of band management interfaces are ICMP only and do not support any SNMP.
It would be a great feature to have if the IP address and status of the out of band management on the server could be represented with the node in a server specific resource like:
it could be defined within the setup for the node and appear like the node status shown above with browser integration so you could write mouseclick and web browse to the Ativan management on the server.
