This document summarizes Marcel Hecko's open source NagMap add-on for visualizing monitoring data on maps. NagMap takes data from Nagios and plots it on Google Maps, allowing users to geographically view the status of monitored systems. The add-on has gained popularity due to its simplicity while still supporting diverse environments. Common user questions involve installation and configuration issues that are often solved by adding or correcting location coordinates in the Nagios configuration file.
