Fritz!Box Upnp statistics exporter for prometheus

This exporter exports some variables from an AVM Fritzbox to prometheus.

This exporter is tested with a Fritzbox 7590 software version 07.12 and 07.20.

The goal of the fork is:

• allow passing of username / password using evironment variable
• use https instead of http for communitcation with fritz.box
• move config of metrics to be exported to config file rather then code
• add config for additional metrics to collect (especially from TR-064 API)
• create a grafana dashboard consuming the additional metrics

Other changes:

• replaced digest authentication code with own implementation
• improved error messages

Building

go get github.com/sberk42/fritzbox_exporter/
cd $GOPATH/src/github.com/sberk42/fritzbox_exporter
go install

Running

In the configuration of the Fritzbox the option "Statusinformationen über UPnP übertragen" in the dialog "Heimnetz > Heimnetzübersicht > Netzwerkeinstellungen" has to be enabled.

Usage:

$GOPATH/bin/fritzbox_exporter -h
Usage of ./fritzbox_exporter:
  -gateway-url string
    The URL of the FRITZ!Box (default "http://fritz.box:49000")
  -listen-address string
    The address to listen on for HTTP requests. (default "127.0.0.1:9042")
  -metrics-file string
    The JSON file with the metric definitions. (default "metrics.json")
  -password string
    The password for the FRITZ!Box UPnP service
  -test
    print all available metrics to stdout
  -json-out string
    store metrics also to JSON file when running test   
  -username string
    The user for the FRITZ!Box UPnP service

The password (needed for metrics from TR-064 API) can be passed over environment variables to test in shell:
read -rs PASSWORD && ./fritzbox_exporter -username <user> -test; unset PASSWORD

Exported metrics

start exporter and run curl -s http://127.0.0.1:9042/metrics

Output of -test

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!)

For a list of all available metrics, see the dumps below (the format is the same as in the metrics.json file, so it can be used to easily add further metrics to retrieve):

• FritzBox 7590 v7.12
• FritzBox 7590 v7.20

Grafana Dashboard

The dashboard is now also published on Grafana.
