NagiosVMA - VMTN Virtual Appliances

NagiosVMA is virtual machine appliance that runs Nagios, a powerful, open-source application which performs host, service and network monitoring. Additionally, the appliance was enhanced with Groundwork Monitor Architect, an open-source, web-based, configuration tool for Nagios. It is intended to offer the end-user sophisticated network monitoring in minutes, instead of hours, (or even days) as is typical with building and configuring a Linux/Nagios host. Using Nagios combined with Monarch and Monarch's automatic host discovery feature, this virtual machine appliance can be booted, configured, and ready to monitor your network in as little as 10 minutes. (in fact, as soon as it boots, its already monitoring this virtual machine appliance!)
