Maps filter the complexity of your IT system in much the same way that a long exposure can draw attention to one element of a cityscape. Whether you watch traffic patterns at dusk or traffic patterns in a segment of your IT infrastructure, maps help make behavior of interest easier to see.
Today's Lumeta maps are network topology renderings that integrate your institution's understanding of its infrastructure (including its unique IoT and in-house descriptors of networked equipment) with Lumeta-indexed data. Maps make network data visual, facilitating understanding and communication within and across business units.
Maps Depend on Path Discovery
Maps depend on Path Discovery. If Path Discovery is not enabled, Lumeta cannot generate a map.
When Path Discovery is enabled, a select set of information is also gathered via SNMP. This information includes system, interface, route table, and ARP table data. This data enables Lumeta to determine that devices are attached to a particular device.
If a device cannot be traced to from a device that has been input or uploaded to Lumeta's Target List, it will not display on the map.
If you attempt to open a map (by selecting a zone from the Maps dropdown menu) and an empty page comes up, the likely problem is that either Path Discovery was not enabled or there were no forwarding devices present in the discovery space defined for that zone.
