Prometheus exporter for NSD (Name Server Daemon)
nsd_exporter will try to autodetect configuration on most Linux distros by reading /etc/nsd/nsd.conf.
You will need to launch the process as a user that has permissions to the NSD control certificate and private key (default /etc/nsd/nsd_control.key, /etc/nsd/nsd_control.pem)
# Defaults listening to 127.0.0.1:8080/metrics
% nsd_exporter
# Specify a different port to listen on
% nsd_exporter -listen-address :9167
# Specify an alternate configuration location to autodetect from
% nsd_exporter -config-file /opt/nsd/nsd.conf
# Manually specify NSD socket and certificates
% nsd_exporter -ca /etc/nsd/nsd_server.pem -key /etc/nsd/nsd_control.key -cert /etc/nsd/nsd_control.pem -nsd-address 127.0.0.1:8952
