Custom dashboards provisioning
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Kolla Ansible sets custom dashboards provisioning using `Dashboard provider <https://grafana.com/docs/grafana/latest/administration/provisioning/#dashboards>`_.
Dashboard JSON files should be placed into the
``{{ node_custom_config }}/grafana/dashboards/`` folder. The use of
sub-folders is also supported when using a custom ``provisioning.yaml``
file. Dashboards will be imported into the Grafana dashboards 'General'
folder by default.
Grafana provisioner config can be altered by placing ``provisioning.yaml`` to
``{{ node_custom_config }}/grafana/`` folder.
For other settings, follow configuration reference:
`Dashboard provider configuration <https://grafana.com/docs/grafana/latest/administration/provisioning/#dashboards>`_.
