knot_exporter is a Prometheus exporter for Knot DNS's server and query statistics.
knot_exporter uses Python libknot wrapper to communicate with the Knot DNS server via a control unix socket, so Knot has to be installed on the same machine as knot_exporter, and knot_exporter must be executed by a user with access to Knot's socket path.
The Knot instance also needs to be configured to collect per-zone query statistic. This can be done by enabling and configuring the stats module.
Once everything is in place, knot_exporter can be started like so:
$ ./knot_exporter --knot-library-path /path/to/libknot.so
To get a complete list of the available options, run:
$ ./knot_exporter --help
