This is NOT recommended, as it makes it impossible to differentiate
between multiple metrics.
Example
=======
An example of a configuration that sends ``telegraf`` metrics to remote
``InfluxDB 2``
.. code-block:: none
set service monitoring telegraf influxdb authentication organization 'vyos'
set service monitoring telegraf influxdb authentication token 'ZAml9Uy5wrhA...=='
set service monitoring telegraf influxdb bucket 'bucket_vyos'
set service monitoring telegraf influxdb port '8086'
