Monitoring
----------
Network Interfaces
^^^^^^^^^^^^^^^^^^
It's possible to monitor network traffic, either at the flow level or protocol
level. This can be useful when troubleshooting a variety of protocols and

can be captured (by default, 1,000 packets are captured and you're returned to
the VyOS command prompt).
Interface Bandwith
^^^^^^^^^^^^^^^^^^
to take a quick view on the used bandwith of an interface use the ``monitor bandwith`` command
.. code-block:: sh
vyos@vyos:~$ monitor bandwidth interface eth0
show the following:
.. code-block:: sh
eth0 bmon 3.5
Interfaces │ RX bps pps %│ TX bps pps %

Interface performance
^^^^^^^^^^^^^^^^^^^^^
To take a look on the network bandwith between two nodes, the ``monitor bandwidth-test`` command is used to run iperf.
.. code-block:: sh
vyos@vyos:~$ monitor bandwidth-test
Possible completions:
accept Wait for bandwidth test connections (port TCP/5001)
initiate Initiate a bandwidth test
| The ``accept`` command open a listen iperf server on TCP Port 5001
| The ``initiate`` command conncet to this server.
.. code-block:: sh
vyos@vyos:~$ monitor bandwidth-test initiate
Possible completions:
<hostname> Initiate a bandwidth test to specified host (port TCP/5001)
<x.x.x.x>
<h:h:h:h:h:h:h:h>
