NMServer provides Inventory and alarm information for Configuration Center, Chassis View,
Diagnostic Center or Statistics Report GUIs. The node information is pushed by topod to NMServer. The
initial inventory of card, lines, ports, etc., is read from the database. The dynamic updates are pushed to
NMServer from topod, ooemc and sdbroker.
