|
|
`yanic` is a respondd client that fetches, stores and publishes information about a Freifunk network. The goals:
|
|
* Generating JSON for [Meshviewer](https://github.com/ffrgb/meshviewer)
|
|
* Storing statistics in [InfluxDB](https://influxdata.com/) or [Graphite](https://graphiteapp.org/) to be analyzed by [Grafana](http://grafana.org/)
|
|
* Provide a little webserver for a standalone installation with a meshviewer
|
|
|
|
## How it works
|
|
In the first step Yanic sends a multicast message to the group `ff05::2:1001` and port `1001`.
|
|
Recently seen nodes that does not reply are requested via a unicast message.
|
