Unfortunately this only works if you have the entire network topology on a map and it doesn't have dual uplinks. If you have a "services" map that has a bunch of hosts but no interconnections, it doesn't work. If you have a map that had 2 different paths back to the intermapper server, it doesn't work. The inability to fine tune notifications for dependent services when the network was redundant (or not drawn) led our unit to recently standardize on Nagios for monitoring going forward instead of InterMapper (which we have used for years). Once the transition is complete, Networking will continue to use Intermapper for our detailed maps, and some monitoring, but the majority of our monitoring needs will be switched over to Nagios, since servers and services monitoring have become as critical as Network monitoring, and the ability to script additions to monitoring and to provide detailed dependency info for notifications was deemed more critical than excellent graphical maps for systems and services. Networking's need for excellent maps was recognized, so we're making a dual-product system. > Please get back to me if you have further questions.
