PingView is a simple network monitor that can monitor your local network and Internet connection. After running an initial wizard, it creates a visual tree of important network components. You can then set it to periodically check that all your important network devices are on-line and accessible.
PingView segregates targets into vital and non-vital (default) allowing you to customize the monitoring by marking important nodes as vital, which will cause immediate report actions if they become unavailable. There is also an option to add comments for repair actions to each items properties, allowing you to keep notes for device specific troubleshooting easily accessible.
