+The systems that are being monitored in <strong>gnucomo</strong> are called
+<emph>Object</emph>.
+These may be computers, routers, switches or other active components that
+are capable of sending reports about their internal workings
+to the <strong>gnucomo</strong> server.
+An <emph>Object</emph> plays a central role in the <strong>gnucomo</strong> system.
+Two separate aspects of an <emph>Object</emph> are monitored: the static state and the
+dynamic behaviour.
+The static state of an <emph>Object</emph> is represented by a set of paremeters
+and the values of these parameter's attributes.
+The dynamic behaviour of an <emph>Object</emph> is characterized by events that
+happen on an <emph>Object</emph>.
+One obvious way to collect a report of these events is to scan the log files of the
+system and its processes.
+<emph>Objects</emph> run services and these services are configured with a set
+of parameters. Also, services produce entries in log files.
