PingerThinger is a ping-based network monitoring tool that tracks which IPs on your LAN / WAN are not responding. PingerThinger provides at-a-glance network status and a window listing all down IPs. Small enough to fit on a floppy or USB flash drive, its compact executable size allows it to be used in disaster recovery. PingerThinger offers scalability; you can monitor any sized network from 1 IP to over 1,000. Besides logging to a file, PingerThinger allows logging to the serial port for monitoring by signboard software. It is enterprise ready and currently in use monitoring a large LAN.
