Figure 16-27. Dependencies of monitored hosts shown graphically

How Nagios arranges the hosts in the graphics is defined by the parameter default_statusmap_layout (A.2.1 Authentication parameters) in the configuration file cgi.cfg. The layout can also be changed with a selection window in the Web interface (at the top right in Figure 16-28). The figure shows the demo system of Netways,[155] whose appearance depends on user-specific coordinates, which in this case you have to specify individually for each host (see 16.4.1 Extended host information). The question mark icon supplied by Nagios has been replaced with nicer pictures by the operator of the site. Coordinates and icons are defined with the hostextinfo object, described in more detail in 16.4.1 Extended host information).
