Clear network metrics
=====================

Important: By following this guide you will clear all the network metrics for all your clients. THIS IS NOT REVERSIBLE.

Currently, the metrics are calculated by aggregating two factors:

- metrics collected by Fleio
- metrics collected by Gnocchi

In order to clear all the network metrics you will have to clear the metrics collected by Fleio in the Fleio database,
and the metrics collected by Gnocchi.

To clear the metrics collected by Fleio you will have to run ``fleio mysql`` command and clear the information
gathered in the following two tables:

.. code-block:: python

    DELETE FROM openstack_networkportresource;
    DELETE FROM openstack_networkporttraffic;

After that, you will have to clear all the information gathered by Gnocchi in all the regions that you have configured
(you will have to run the following for loop in each region).

.. code-block:: bash

    for f in `openstack metric resource list --type instance_network_interface -f value -c id`;do openstack metric resource delete $f;done

After that, just run the ``collect_traffic_data`` script on your Fleio installation:

.. code-block:: bash

    fleio bash
    sh /var/webapps/fleio/scripts/collect_traffic_data
