With IPHost Network Monitor you can run simple snmp requests against a Cisco device in your network.
appnNnTopoCurNumNodes
appn Network Node Topology Current Number Nodes
1.3.6.1.2.1.34.4.1.2.1.2
Current number of node entries in this node's topology database. It is an implementation choice whether to count only network-node entries, or to count all node entries, but an implementation must make the same choice here that it makes for the appnNnTopoMaxNodes object. If this value exceeds the maximum number of nodes allowed (appnNnTopoMaxNodes, if that field in not 0), APPN Alert CPDB002 is issued.
