system-state not updated when there is no data
if the server.sh is not running at a server then there is no monitoring-data for this server (this occurs, if the log-file is present (by a killed or hanged server.sh) and so the server.sh is not running).
this is not "found" by the monitor. means, the monitor tells "system ok" but it is NOT.
the monitor has to check if there is any "NEW" data and if not, the system is not o.k.
