PingGraph helps find and diagnose network problems by graphing ping times and and estimated bandwidth available on multiple connections. Email alerts inform you of networking trouble. Data is saved in an easy-to-use XML format. Graphs are configurable to show a wide range of time scales from 10 minutes to a year, allowing you to quickly identify short and long term trends, connectivity problems and packet loss. The XML log file size is automatically managed so you don't have to worry so much about disk space.
