The exporter prints all available Variables to stdout when called with the -test option.
These values are determined by parsing all services from http://fritz.box:49000/igddesc.xml and http://fritzbox:49000/tr64desc.xml (for TR64 username and password is needed!!!)
## Customizing metrics
The metrics to collect are no longer hard coded, but have been moved to the metrics.json file, so just adjust to your needs.
For a list of all the available metrics just execute the exporter with -test (username and password are needed for the TR-064 API!)
