Program NetMap watches hosts to be accessible via protocol ICMP.

For this purpose the program periodically sends requests, completely similar to requests of program ping and checks for replies, which indicates activity of hosts and proper functioning of network connections. By default, program waits for response within 4 seconds.

Program looks for hosts to which the requests are sent, within a given list in a cyclic order. Minimal interval between consecutive requests is adjusted in the range from 100 mls to 10 min.

The list can contain a plenty of hosts (more than one hundred), whereas the main window of the program allows to select for observation up to seventy of them to one's liking. Received replies are accumulated in the daily protocol, which can be viewed as either graphic or text report, printed and kept in a file for the archiving purposes.

The graphic protocol has per minute resolution.

NetMap can save detailed logs and send mail. Functions of program can be extended thereby external batch files (plugins).

If necessary, one can adjust NetMap to load at startup and to work in automatic mode as system service. For minimal loading of CPU the program can be minimized to a tray icon. Tray icon indicates state of the most problem host, determined thereby analysis of its latest replies.
