Configure Control Socket

The exporter uses Kea’s control socket and the statistic-get-all request. Consult the documentation on how to set up the control socket:

• http://kea.isc.org/docs/kea-guide.html#dhcp4-ctrl-channel

• http://kea.isc.org/docs/kea-guide.html#dhcp6-ctrl-channel

Permissions

Kea Exporter needs to be able to read and write on the socket, hence it’s permissions might need to be modified accordingly.
