Additionally, +if you want to take advantage of the autodetection this plugin offers, +you will need to make sure your `unbound.conf` file only uses spaces for +indentation (the default config shipped by most distributions uses tabs +instead of spaces). + +Once you have the Unbound control protocol enabled, you need to make sure +that either the certificate and key are readable by Netdata (if you're +using the regular control interface), or that the socket is accessible +to Netdata (if you're using a UNIX socket for the contorl interface). + +By default, for the local system, everything can be auto-detected +assuming Unbound is configured correctly and has been told to listen +on the loopback interface or a UNIX socket. This is done by looking +up info in the Unbound config file specified by the `ubconf` key. + +To enable extended stats for a given job, add `extended: yes` to the +definition. + +You can also enable per-thread charts for a given job by adding +`per_thread: yes` to the definition.
