Configuration File
------------------

As in some case it is convenient to have a configuration file to be used in 
place of command line options (this is mandatory when running the application 
as a service with systemd for instance), it is possible to start nProbe Agent 
providing a configuration file path as follows:

.. code:: bash

   nprobe-agent <configuration file path>

where the configuration file contains the same options otherwise specified in 
the command line. The only difference between the command line and the configuration 
file is that different options need to be specified on different lines. For instance:

.. code:: bash

   nprobe-agent --zmq tcp://127.0.0.1:1234c -l

is the same as:

.. code:: bash
   
   nprobe-agent /etc/nprobe-agent/nprobe-agent.conf

where */etc/nprobe-agent/nprobe-agent.conf* contains the following lines:

.. code:: bash

   # cat /etc/nprobe-agent/nprobe-agent.conf
   --zmq=tcp://127.0.0.1:1234c
   -l
