Figure 7-18. Nagios home page
For my example, I can click the Map option on the left of the home page to see the Nagios cluster map showing
the server objects that were created under /etc/nagios/conf.d on hc1nn (bottom right of Figure 7-19 ). I select a server
icon (such as for hc1nn) in the Nagios map to display the details for that server, as shown on the left of Figure 7-19 .
