Both a host name and IP address can be monitored should you want to bypass DNS look-ups or your CDN. It features monitor one host and/or one IPV4 address, logging of individual ping stats, file download stats and file download time stats, as well as totals and averages, settings for delay times, ping threshold, notification level, and notification type , set a custom user agent for HTTP requests, and quick access to all functions through a tray icon.
