How Does NetWatcher Work?
(1). NetWatcher pings the server at a given rate and works the amount of "Hits & Misses" into a "UP-Time & DOWN-Time Percentage"
(2). It keeps track of how long the server takes to respond and keeps a "Shortest-Time & Longest-Time" record.
(3). It changes the tray icon from a "Green-Check" to a "Red-Dash" depending on if the server is responding or not.<<less
