The probes (for example in [[:en:documentation:pandorafms:monitoring:15_raspberry_monitoring|Raspberry]]) are generally routers with NetFlow enabled, configured, and sending information to the NetFlow collector (which in this case will be Pandora FMS server with the nfcapd daemon enabled).

The probes (for example in [[:en:documentation:pandorafms:technical_annexes:15_raspberry_monitoring|Raspberry]]) are generally routers with NetFlow enabled, configured, and sending information to the NetFlow collector (which in this case will be Pandora FMS server with the nfcapd daemon enabled).
**fprobe** captures traffic and sends it to a NetFlow Server. You may generate NetFlow traffic with it, among all the traffic that goes through its interfaces.
+
The **fprobe** software captures traffic and forwards it to a NetFlow® server. Through that you may generate NetFlow traffic from all network traffic going through your interfaces.
For instance, executing this command, all ''eth0'' interface traffic will be sent to the NetFlow collector listening on port ''9995'' of the IP address ''192.168.70.185'':
+
The installation offers ''eth0'' as default interface, it must be configured with a valid network interface; in recent distros the Ethernet interface is named ''enp1s0'' and the wireless network interface ''wlp2s0'', **depending on the hardware these names may vary**.
It will then query for the IP address and listening port of the device that will collect the data (in this case the **PFMS server**), e.g. ''192.168.70.185:9995''.
-
/usr/sbin/fprobe -i eth0 192.168.70.185:9995

次に、データを収集するデバイス (この場合は **PFMS サーバ**) の IP アドレスと待ち受けポート (例: ''192.168.70.185:9995'') を確認します。

Once the traffic has been generated, you may see its statistics in the NetFlow collector by entering this command:

Once the installation has been completed, the operation can be tested:
-
トラフィックが生成されたら、次のコマンドでトラフィックの状態を見る事ができます。

It is possible to locate the Pandora FMS node that collects NetFlow data in a host independent from the Console. In environments with a lot of NetFlow data, it is more than recommended to locate it in a server with fast disks and a fast CPU with two cores or more. For the Pandora FMS Console to be able to extract NetFlow data, it will be necessary to modify the default configuration of the system:
