  • the database is access in read only mode from Grafana
• add MaxMind license for the API server: the license should be configurable using the UI
• apply retention also to Timescale database

Test case 1

• Make sure to install on NS8 with core 3.1.0-dev.3or greater
• Register the NS8 with a valid subscription: the historical monitoring requires a subscription both on the NethSecurity and NethServer 8
• Install a new instance of the controller: add-module ghcr.io/nethserver/nethsecurity-controller:1.1.0-dev.3
• Access the module UI and configure it , including the new Max Mind license field
• Save the configuration
• Verify the controller is accessible and units with a subscription can be registered
• Follow the unit test case

Test case 2

• Make sure to install on NS8 with core 3.1.0-dev.3 or greater
• Update an existing instance where there is at least one unit connected: api-cli run update-module --data '{"module_url":"ghcr.io/nethserver/nethsecurity-controller:1.1.0-dev.3","instances":["nethsecurity-controller1"]}'
• Verify the units still reconnect after the upgrade
• Check the timescale database is running: runagent -m nethsecurity-controller8 podman ps

test 1 verified

once the controller up and the nethsecurity unit up with registration on the both side, the data is visible in grafana without action of the sysadmin after few minutes
the page of the controller in the nethsecurity web page show us that the data is well sent to grafana
