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
If nsd has a new version with new metrics or you want to change the description of the existing metrics, you can make changes to the metrics that nsd_exporter emits by using your own metrics config file.
- Download the metrics config from
config/config.yaml - Make any additions or modifications you want.
- Load it by running
nsd_exporter -metric-config my-custom-config.yaml. This will use your config instead of the internal metrics config file.
This is only needed if you want to modify the embedded metric configuration file.
Install go-bindata.
go install github.com/go-bindata/go-bindata/go-bindata@latest
Make any metric config modifications to config/config.yaml.
Run go generate to generate a new embedded config file. Don't forget to check it in.
