`respond-collector` is a respondd client that fetches, stores and publishes information about a Freifunk network. The goals:
* Generating JSON for [MeshViewer](https://github.com/ffnord/meshviewer) (Works with branch [JSONv2](https://github.com/FreifunkBremen/meshviewer/tree/JSONv2))
* Storing statistics in [InfluxDB](https://influxdata.com/) to be analyzed by [Grafana](http://grafana.org/)
* Provide information via JSON-APIs
## Usage
```
Usage of ./respond-collector:
-config path/to/config.yml
```
## Development
### respond
It sends the `gluon-neighbour-info` request and collects the answers.
It will send UDP packets with multicast group `ff02:0:0:0:0:0:2:1001` and port `1001`.
### nodes.Nodes
It caches the information of the nodes and will save them periodical to a JSON file.
The current nodes are saved default under `nodes.json`.
