From the developer: "Monitors your switches (and optionally routers) for network performance. Uses web-based reporting to show you utilization and errors on each interface on your network. SwitchMonitor sends a daily emailed Network 'Weather Report'(TM) so you can keep a daily tab of the health and performance of your network. View daily, weekly, monthly, and yearly historical utilization information on each interface. Collects network device information to help document your network. Setup and auto-configuration can be accomplished in under 10 minutes for virtually any sized network."
