The NagVis automap included with op5 Monitor is a great tool for visualizing the parent-child relationship of hosts in the monitoring system.
This map is however configured to a static size and can get a bit unreadable once you have added more hosts with multiple parents and children.
In this how-to we will look at configuring the automap for large environments and replicate some of the functionality from the deprecated Hypermap feature.
The automap in an environment with a lot of host relationships
Open the NagVis map called "Automap", hover over the "Edit map" menu and select "Map options" button
Scroll down the options list to "render_mode" and set it to "unidirect2".
This should render a cleaner and more spread out map with your hosts and their relationships
