There are cases where you may require nProbe to act as a sort of “hub” for collection, such as behind a NAT. Once this configuration is saved and the services started, you are ready to start viewing flow data in ntopng. Here we select the NetFlow version, as well as any fields we want to decode from the flow. The final step, is to configure the “Flow Export Format”. We will now instruct nProbe to create this socket by setting the “ZeroMQ Endpoint” to “tcp://127.0.0.1:5556”. In the previous step, we configured ntop to connect to a ZMQ socket on localhost. The listening port is where the NetFlow exporter should send to.

Here we configure our “Listening Port”, and “ZMQ Endpoint”, and “Flow Export Format”. In the nBox UI, navigate to “Appplication > nProbe”, and select the “Proxy” tab. We must now configure nProbe to listen for incoming NetFlow traffic, decode it, and publish it to ntopng. Once the changes are saved, we will see this in the list of Interfaces in ntop. In our case, we have nProbe running on the same machine, so we will be connecting to a socket on localhost. We then specify our address for the “Collector Endpoints”. Under Interfaces, we will select “Collector Only” In this example, we are going to use ntopng only as a NetFlow collector.

This will be a connection to a ZeroMQ socket that we will configure nProbe to create in the next step.įrom the nBox UI, navigate to “Applications > ntopng”, and select the configuration tab. While we generally have overarching performance issues with our VM host, this should not be occurring at all. Our first task is to configure an interface for ntopng to listen on. NTOPNG spontaneously stops exporting flows 2298 Closed CDawson1 opened this issue on 44 comments CDawson1 commented on I've had this issue pop up a few times now and I'm not sure what the trigger is. Ntopng and nProbe utilize ZeroMQ. This gives us greater control over how our flow data can be distributed to collectors. In this article we will cover two ways to configure nProbe using proxy mode using the nBox graphical interface, so that we may forward flows to either ntopng or another collector such as SolarWinds NTA.

The full version can be purchased at the official site of are numerous ways to configure nProbe to work with NetFlow. NOTE: This is a DEMO version limited to 25000 flows export. NOTE: This is a DEMO version limited to 25000 flows export. To receive NetFlow data and transfer it to ntopng, create a file (in the nano editor, press CTRL+X to exit, y/x to save or discard changes).

In the free version of nprobe, I had a message: Therefore, if necessary, you can stop it like this: sudo killall nprobe For this reason n2disk has been extended to be able to export statistics and flows metadata to other analysis tools through ZMQ. I noticed that nprobe does not always shut down after the command: sudo /etc/init.d/nprobe stop Flows Export Using n2disk with other tools like ntopng is often convenient for for extending continuous traffic recording with traffic analysis/visualization. It remains to restart ntopng to apply the changes: sudo service ntopng restartĬheck whether everything works: sudo netstat -tulpen | grep 2055 Now it remains to open the ntopng configuration in a text editor: sudo nano /etc/ntopng/nfĪnd add a line at the end (thereby adding the nprobe interface to collect statistics): -interface='tcp://127.0.0.1:5556' Setting up and using Traffic Flow in Mikrotik See my articles on configuring NetFlow on switches: To receive NetFlow data and transfer it to ntopng, create a file (in the nano editor, press CTRL+X to exit, y/x to save or discard changes): sudo nano /etc/nprobe/nfĢ055 is the port on which you want to receive NetFlow data, and port 5556 is used to transmit it to ntopng.
