Sensors

Depending on the method of data acquisition one “sensor” can be:

·      For SNMP traffic sensors: One sensor monitors the in- and out-going traffic of one port of a device (e.g. a port of a switch or a network card of a PC).

·      For other SNMP Sensors: A sensor monitors one single parameter (e.g. the CPU usage or room temperature)

·      For Packet Sniffing: One sensor monitors all traffic going through one or more network cards. Several sensors can monitor the same network card using different filter settings (e.g. to monitor only specific IPs or protocols)

·      For NetFlow monitoring: One sensor monitors all NetFlow data packets arriving at one NetFlow Collector. Usually one Network Collector is installed per switch. Several sensors can monitor the same NetFlow Collector using different filter settings (e.g. to monitor only specific IPs or protocols)

In the main window the list of all sensors can be seen on the left side. The colors show the states of the sensors.

Sensors are organized in collapsible groups. Groups are shown in red or yellow if one or more of the group’s sensors are not OK (i.e. not green).
