Server Reachability Checker description

Check periodically whether specified server addresses are reachable, and receive notifications for unavailable servers.
You can chose from several possibilities how the reachability is checked (e.g. ping or open a socket to a specific port), or use the check type 'Automatic' in order to use the first method which detects that your address is reachable.
The most recent results will be saved, so it is possible to distinguish when and how long which address was (not) reachable in the past.
