A very simple method was devised to watch a program to make sure it is still executing. This only works if the program was coded with this scheme in mind. It is not currently possible to watch any or all programs. Periodically, NTpage Watcher Service looks for a certain file on the disk. If it finds it, it renames that file to another name. Your program must periodically rename that file back to the original name that the Watcher is looking for. If the watcher program fails to see the file for a period of time, it will send out an alarm. |
