In our production we have network with ~100 nodes. Each node have some equipment(switches, ups, DSLAM. etc.) and geographically located in one place.One node correspond one group in zabbix and have one map with all items of node. For viewing all nodes we have one global map with "network group" items corresponding network nodes. Now we manually adding link on global map for going from global map to network node map after adding new node of network. It will be nice if in zabbix we have instrument for automatic linking between maps and tool for navigation.
