+#Monitoring services
+The monitoring services build in real time an archive of observations obtained from the analisys of the communication flows of the CELL application services.
+The observations could be checked in real time (directly in memory) against attacks, anomalies or errors.
+The observations, once processed in real time, are stored into a persistent archive for statistic analisys and reports generation.
+
+### Config the port to be monitored
+Admin can configure the tcp ports to be monitored by the monitoring services, by adding the following two lines:
+* # the monitoring services will have to monitor the following ports
+* PORTS_TO_BE_MONITORED = list(PEER_SERVICE_PORTS.items()) + list(CA_SERVICE_PORTS.items())
+to the configuration file: /src/common/utils.py
+
+### Config the monitoring level
+Admin can add to the file /src/monitoring/config.py the following flags:
+* MONITOR_DB=<file name or network path where to store the persistent archive>
+* MONITOR_LEVEL=FULL | SIMPLE | NONE
