# Fritz!Box Upnp statistics exporter for prometheus

This exporter exports some variables from an
[AVM Fritzbox](http://avm.de/produkte/fritzbox/) to prometheus.

This exporter is tested with a Fritzbox 7590 software version 07.12, 07.20, 07.21 and 07.25.

The goal of the fork is:
  - [x] allow passing of username / password using evironment variable
  - [x] use https instead of http for communitcation with fritz.box
  - [x] move config of metrics to be exported to config file rather then code
  - [x] add config for additional metrics to collect (especially from TR-064 API)
  - [x] create a grafana dashboard consuming the additional metrics
  - [x] collect metrics from lua APIs not available in UPNP APIs
 
Other changes:
  - replaced digest authentication code with own implementation
  - improved error messages
  - test mode prints details about all SOAP Actions and their parameters
  - collect option to directly test collection of results
  - additional metrics to collect details about connected hosts and DECT devices
  - support to use results like hostname or MAC address as labels to metrics
  - support for metrics from lua APIs (e.g. CPU temperature, utilization, ...)

## Building

```shell script
git clone https://github.com/chr-fritz/fritzbox_exporter.git
cd fritzbox_exporter
go mod download
go build
```

Alternatively there is a [`Dockerfile`](Dockerfile) to build a docker
image.

```shell script
docker build -t fritzbox-exporter .
```

## 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")
  -gateway-luaurl string
    The URL of the FRITZ!Box UI (default "http://fritz.box")
  -metrics-file string
    The JSON file with the metric definitions. (default "metrics.json")
  -lua-metrics-file string
    The JSON file with the lua metric definitions. (default "metrics-lua.json")
  -test
    print all available SOAP calls and their results (if call possible) to stdout
  -json-out string
    store metrics also to JSON file when running test   
  -testLua
    read luaTest.json file make all contained calls and dump results
  -collect
    collect metrics once print to stdout and exit
  -nolua
    disable collecting lua metrics
  -username string
    The user for the FRITZ!Box UPnP service
  -password string
    The password for the FRITZ!Box UPnP service
  -listen-address string
    The address to listen on for HTTP requests. (default "127.0.0.1:9042")
```
    
The password (needed for metrics from TR-064 API) can be passed over environment variables to test in shell:
```shell script
read -rs PASSWORD && export PASSWORD && ./fritzbox_exporter -username <user> -test; unset PASSWORD
```

### Running with docker

The fritzbox-exporter will be built by the Docker Hub Infrastructure
which can be used with:

```shell script
docker run -p 8080:8080 chrfritz/fritzbox-exporter
```

It supports all commandline arguments like the original one:

```shell script
docker run chrfritz/fritzbox-exporter -h
```

See also <https://hub.docker.com/r/chrfritz/fritzbox-exporter>.

## Exported metrics

Start the exporter and run:

```shell script
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. It retrieves these values by parsing all services
from <http://fritz.box:49000/igddesc.xml> and
<http://fritzbox:49000/tr64desc.xml>. To access TR64 the exporter needs
username and password.

## Customizing metrics

The metrics to collect are no longer hard coded, but have been moved to the [metrics.json](metrics.json) and [metrics-lua.json](metrics-lua.json) files, 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 lua metrics open UI in browser and check the json files used for the various screens.

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](all_available_metrics_7590_7.12.json)
- [FritzBox 7590 v7.20](all_available_metrics_7590_7.20.json)
- [FritzBox 7590 v7.25](all_available_metrics_7590_7.25.json)
## Grafana Dashboard

The dashboard is now also published on
[Grafana](https://grafana.com/grafana/dashboards/12579).
