An organization with a large distributed network can use a separate InterMapper server within each remote site or region. In essence, each site or region has its own InterMapper ?polling engine?, putting the polling engine as close as possible to the devices being monitored.
This design allows for monitoring of equipment behind corporate firewalls, and provides resiliency in the face of WAN outages. Network managers at the remote sites can continue to monitor their site or region even when WAN connectivity is down.
The Map Status probe can be used to create top-level maps showing the summary status of the networks at all sites or regions. When network managers at the main site see a network problem on a top-level map they can drill down to open the maps on the InterMapper server for the site or region to diagnose the problem.
